Calendar, diary, appointments stuff. ;; See doc strings of functions `calendar-mode' and `calendar'. ;; ;; ;; Main new functions defined here: ;; ;; `calendar-count-weekdays-region', `calendar-local-holiday-list', ;; `calendar-mouse-3-menu', `calendar-mouse-drag-region', ;; `mark-local-holidays', `monday-after-easter', ;; `set-calendar-region-from-region', `show-calendar'. ;; ;; New user options defined here: ;; ;; `cal-mode-line-key-help', `calendar-local-holiday-marker', ;; `calendar-region-marker', `weekend-face'. ;; ;; ;; ***** NOTE: The following functions defined in `calendar.el' have ;; been REDEFINED HERE: ;; ;; `calendar-basic-setup' - ;; 1) `list-calendar-holidays' is now called by `calendar' on the ;; 3-month period starting with the current month, not with the ;; previous month. The rationale is that you want to be ;; informed of future, not past, holidays. This means that the ;; holidays listed by `calendar', when ;; `view-calendar-holidays-initially', are one month later than ;; those listed by `list-calendar-holidays'. ;; 2) Fixed bug: ARG's value & sign was not being taken into ;; account previously. Now, distinguish between the case where ;; ARG is explicitly numeric (in which case, use its value as ;; is), and the C-u-only case (in which case, prompt for month ;; and year). ;; `calendar-count-days-region' - Marks days in region if visible. ;; `calendar-mode' - New doc string. ;; `generate-calendar-month' - Puts weekend days in `weekend-face'. ;; `mark-visible-calendar-date' - ;; Doesn't add a new overlay if one is already present with face ;; MARK. (To allow for overlapping overlays.) Arg PRIORITY is new. ;; ;; ;; ***** NOTE: The following function defined in `solar.el' ;; has been REDEFINED HERE: ;; ;; `solar-sunrise-sunset-string' - Avoid being seen as appt time. ;; ;; ;; ***** NOTE: The following function defined in `diary-lib.el' ;; has been REDEFINED HERE: ;; ;; `insert-diary-entry' - ;; When `european-calendar-style', this inserts `26 Jan 1995 :' ;; instead of `26 Jan 1995'. NOTE: This definition is coupled ;; with that of `european-date-diary-pattern' (which also has " :" ;; at the end of a diary entry). ;; ;; ;; The following binding is made here for mode `calendar-mode'. ;; ;; `=' `calendar-count-days-region' ;; ;; ;; This file redefines a few standard calendar functions. It should ;; be loaded after loading any of the GNU files `calendar.el', ;; `cal-french.el', or `diary-lib.el'.

DAYNAME The remainder of a diary entry line is the entry string proper for the given date. - MONTH and DAY are one or two digit numbers. - YEAR is a number and may be written in full or abbreviated to the final two digits. If the date does not explicitly contain a YEAR, it is generic and applies to any year. - DAYNAME entries apply to any date which is on that day of the week. - MONTHNAME and DAYNAME can be spelled in full, abbreviated to three characters (with or without a period), capitalized or not. - Any of DAY, MONTH, or MONTHNAME, YEAR can be `*' which matches any day, month, or year, respectively. The European style (in which the day precedes the month) can be used instead, if you execute `european-calendar' when in the calendar, or set `european-calendar-style' to t in your ~/.emacs file. The European forms are: DAY/MONTH DAY/MONTH/YEAR DAY MONTHNAME DAY MONTHNAME YEAR : (Note the `:' in this form.) DAYNAME To revert to the default American style from the European style, execute `american-calendar' in the calendar. A diary entry can be preceded by the character `diary-nonmarking-symbol' (ordinarily `&') to make that entry nonmarking--that is, it will not be marked on dates in the calendar window but will appear in a diary window. Multiline diary entries are made by indenting lines after the first with either a TAB or one or more spaces. Lines not in one the above formats are ignored. Here are some sample diary entries (in the default American style): 12/22/1988 Twentieth wedding anniversary!! &1/1. Happy New Year! 10/22 Ruth's birthday. 21: Payday Tuesday--weekly meeting with grad students at 10am Supowit, Shen, Bitner, and Kapoor to attend. 1/13/89 Friday the thirteenth!! &thu 4pm squash game with Lloyd. mar 16 Dad's birthday April 15, 1989 Income tax due. &* 15 time cards due. If the first line of a diary entry consists only of the date or day name, with no trailing blanks or punctuation, then that line is not displayed in the diary window; only the continuation lines are shown. For example, the following (single) diary entry will appear in the diary window without the date line at the beginning: 02/11/1989 Bill Blattner visits Princeton today 2pm Cognitive Studies Committee meeting 2:30-5:30 Lizzie at Lawrenceville for `Group Initiative' 4:00pm Jamie Tappenden 7:30pm Dinner at George and Ed's for Alan Ryan 7:30-10:00pm dance at Stewart Country Day School This can allow the diary window to look neater, but it can also cause confusion when more than one day's entries are displayed. Diary entries can be based on Lisp sexps. For example, this diary entry causes \"Vacation\" to appear from Nov 1 through Nov 10, 2002: %%(diary-block 11 1 2002 11 10 2002) Vacation Other functions available are `diary-float', `diary-anniversary', `diary-cyclic', `diary-day-of-year', `diary-iso-date', `diary-french-date', `diary-hebrew-date', `diary-islamic-date', `diary-mayan-date', `diary-chinese-date', `diary-coptic-date', `diary-ethiopic-date', `diary-persian-date', `diary-yahrzeit', `diary-sunrise-sunset', `diary-phases-of-moon', `diary-parasha', `diary-omer', `diary-rosh-hodesh', and `diary-sabbath-candles'. See the doc for the function `list-sexp-diary-entries' for more details. Diary entries based on the Hebrew and/or the Islamic calendar are also possible, but because these are somewhat slow, they are ignored unless you set the hooks `nongregorian-diary-listing-hook' and `nongregorian-diary-marking-hook' appropriately. See the doc for these functions for details. Diary files can contain directives to include the contents of other files. For details, see the documentation for the variable `list-diary-entries-hook'.")

Whenever it makes sense, calendar commands take prefix arguments that multiply their effect. The digit keys (0-9) and the minus sign (-) are bound to `digit-argument', so they need not be prefixed with `M-'. For example, `2 \\[calendar-forward-week]' provides prefix argument 2 to \ command `\\[calendar-forward-week]'. Mouse Menus ----------- The mouse provides two popup menus in Calendar Mode (provided your Emacs has a mouse): [mouse-2] provides a menu specific to the date under the mouse [mouse-3] provides a more general menu Calendar Movement, Display -------------------------- The calendar window can be refreshed at any time with `\\[redraw-calendar]'. The commands for calendar movement are: `\\[scroll-calendar-right]' scroll one month right \ `\\[scroll-calendar-left]' scroll one month left `\\[scroll-calendar-right-three-months]' scroll 3 months right \ `\\[scroll-calendar-left-three-months]' scroll 3 months left `\\[calendar-goto-today]' display current month \ `\\[calendar-other-month]' display another month Cursor Movement --------------- Cursor movement in Calendar mode is a bit special. It is as if the only possible places for the cursor (point) and the mark were on dates, and buffer positions were ordered chronologically rather than from the top left of the buffer to the bottom right. Thus, if the cursor is at the end of a week and is then moved forward, it does not move to the right, but rather to the next day. The commands for cursor movement are:\\ `\\[calendar-forward-day]' one day forward \ `\\[calendar-backward-day]' one day backward `\\[calendar-forward-week]' one week forward \ `\\[calendar-backward-week]' one week backward `\\[calendar-forward-month]' one month forward \ `\\[calendar-backward-month]' one month backward `\\[calendar-forward-year]' one year forward \ `\\[calendar-backward-year]' one year backward `\\[calendar-beginning-of-week]' beginning of week \ `\\[calendar-end-of-week]' end of week `\\[calendar-beginning-of-month]' beginning of month \ `\\[calendar-end-of-month]' end of month `\\[calendar-beginning-of-year]' beginning of year \ `\\[calendar-end-of-year]' end of year `\\[calendar-goto-date]' go to date `\\[calendar-goto-julian-date]' go to Julian date \ `\\[calendar-goto-astro-day-number]' go to astro. (Julian) day `\\[calendar-goto-hebrew-date]' go to Hebrew date \ `\\[calendar-goto-islamic-date]' go to Islamic date `\\[calendar-goto-iso-date]' go to ISO date \ `\\[calendar-goto-french-date]' go to French Revol'y date `\\[calendar-goto-mayan-long-count-date]' go to Mayan Long Count date `\\[calendar-next-haab-date]' go to next occurrence of Mayan Haab date `\\[calendar-previous-haab-date]' go to previous occurrence of Mayan \ Haab date `\\[calendar-next-tzolkin-date]' go to next occurrence of Mayan Tzolkin \ date `\\[calendar-previous-tzolkin-date]' go to previous occurrence of Mayan \ Tzolkin date `\\[calendar-next-calendar-round-date]' go to next occurrence of Mayan \ Calendar Round date `\\[calendar-previous-calendar-round-date]' go to previous occurrence \ of Mayan Calendar Round date The \"one\" in some of these descriptions is the default. A prefix arg serves as a multiplier, as described above. Thus, e.g. \ `2 \\[calendar-forward-year]' moves the cursor forward two years. The Region ---------- You can set the mark at a date in the calendar. After moving the cursor, a calendar region is defined between the cursor date and the mark date. You can then exchange the cursor and the mark positions. `\\[calendar-set-mark]' mark date \ `\\[calendar-exchange-point-and-mark]' exchange point and mark The region may also be defined as usual via the mouse (if your Emacs has a mouse). In addition, double clicking [mouse-1] on a date selects that date as the region, and highlights it. Triple clicking \[mouse-1] on a date selects that date's week as the region, and highlights it. You can determine the number of days in the calendar region (including the cursor date and the marked date) by: `\\[calendar-count-days-region]' count days in calendar region With a prefix argument (C-u), only weekdays (Mon-Fri) in the region are counted. If the entire region is visible, then \ `\\[calendar-count-days-region]' highlights it. Holidays -------- The following commands deal with holidays: `\\[calendar-cursor-holidays]' give holidays for the date specified by \ the cursor `\\[mark-calendar-holidays]' mark holidays in the calendar `\\[list-calendar-holidays]' display holidays `\\[calendar-unmark]' unmark all dates (not just holidays) The command `\\[mark-calendar-holidays]' causes holidays to be \"marked\" \ \(visually highlighted). `\\[mark-local-holidays]' does the same thing for local holidays. The variable `local-holidays' determines which dates are thus highlighted. Set `view-calendar-holidays-initially' to a non-nil value to display holidays for the current three month period on entry to the calendar. Independently of the calendar, the command `\\[holidays]' displays the holidays for the current, previous, and following month. Solar & Lunar Information ------------------------- To find the times of sunrise and sunset and the dates and times of lunar phases: `\\[calendar-sunrise-sunset]' show times of sunrise and sunset `\\[calendar-phases-of-moon]' show times of quarters of the moon The times given apply to location `calendar-location-name' at latitude `calendar-latitude', and longitude `calendar-longitude'. Set these variables for your location. The following variables are also consulted, and you must set them if your system does not initialize them properly: `calendar-time-zone', `calendar-daylight-time-offset', `calendar-standard-time-zone-name', `calendar-daylight-time-zone-name', `calendar-daylight-savings-starts', `calendar-daylight-savings-ends', `calendar-daylight-savings-starts-time', `calendar-daylight-savings-ends-time'. Equivalent Dates ---------------- These commands express the cursor's date in other ways: `\\[calendar-print-day-of-year]' show day number and number of days \ remaining in year `\\[calendar-print-iso-date]' show equivalent date on the ISO \ commercial calendar `\\[calendar-print-julian-date]' show equivalent date on the Julian \ calendar `\\[calendar-print-astro-day-number]' show equivalent astronomical \ \(Julian) day number `\\[calendar-print-hebrew-date]' show equivalent date on the Hebrew \ calendar `\\[calendar-print-islamic-date]' show equivalent date on the Islamic \ calendar `\\[calendar-print-french-date]' show equivalent date on the French \ Revolutionary calendar `\\[calendar-print-mayan-date]' show equivalent date on the Mayan \ calendar The day number in the year and the number of days remaining in the year can be determined by: Your Diary ---------- The following calendar mode commands control your diary: `\\[mark-diary-entries]' mark diary entries \ `\\[calendar-unmark]' unmark all dates `\\[view-diary-entries]' display diary entries \ `\\[show-all-diary-entries]' show all diary entries `\\[print-diary-entries]' print diary entries The command `\\[mark-diary-entries]' causes diary entries to be \"marked\", \ that is, visually highlighted. `\\[calendar-unmark]' removes all such calendar highlighting, \ not just diary entry marks. The command `\\[print-diary-entries]' prints the diary entries that are shown by `\\[diary]'. The command `\\[diary]' causes the diary entries for the cursor's date to be displayed, independently of the calendar. The number of days of entries is governed by `number-of-diary-entries', but this is overridden by a prefix argument. Unless the variable `diary-display-hook' causes another sort of display (see below), `\\[diary]' displays your diary file itself. You can then edit the diary entries there. (The format of the entries is described in the documentation for variable `diary-file'.) \\BE CAREFUL WHEN EDITING DIARY ENTRIES VIA `\\[diary]': The buffer displayed by `\\[diary]' contains your *entire* diary file, even though you can only see part of it. This means, for instance, that the command `\\[forward-char]' can put the cursor at what appears to be \ the end of the line, but is in reality the middle of some concealed line. \(Inserting additional lines or adding/ deleting characters in the middle of a visible line will not cause problems. Watch out for \ `\\[end-of-line]', however--it may put you at the end of a concealed line far from where the cursor appears to be.) \\Because of this potential for confusion, if you do not use `diary-display-hook', then before editing your diary it is best to display the entire file with `\\[show-all-diary-entries]'. (Be sure to save \ any changes you make to the file.) The following calendar mode commands assist in making diary entries: `\\[insert-diary-entry]' insert a diary entry for the selected date `\\[insert-weekly-diary-entry]' insert a diary entry for the selected \ day of the week `\\[insert-monthly-diary-entry]' insert a diary entry for the selected \ day of the month `\\[insert-yearly-diary-entry]' insert a diary entry for the selected \ day of the year `\\[insert-block-diary-entry]' insert a diary entry for the days \ between point and mark `\\[insert-anniversary-diary-entry]' insert an anniversary diary entry \ for the selected date `\\[insert-cyclic-diary-entry]' insert a cyclic diary entry There are corresponding commands to assist in making Hebrew or Islamic date diary entries: `\\[insert-hebrew-diary-entry]' insert a diary entry for the Hebrew \ date corresponding to the selected date `\\[insert-monthly-hebrew-diary-entry]' insert a diary entry for the \ day of the Hebrew month corresponding to the selected day `\\[insert-yearly-hebrew-diary-entry]' insert a diary entry for the day \ of the Hebrew year corresponding to the selected day `\\[insert-islamic-diary-entry]' insert a diary entry for the Islamic \ date corresponding to the selected date `\\[insert-monthly-islamic-diary-entry]' insert a diary entry for the \ day of the Islamic month corresponding to the selected day `\\[insert-yearly-islamic-diary-entry]' insert a diary entry for the \ day of the Islamic year corresponding to the selected day All of the diary entry commands make nonmarking (i.e. nonhighlighting) entries when given a prefix argument. With no prefix arg, the diary entries are marking. Set variable `view-diary-entries-initially' to a non-nil value to display today's diary entries in another window when the calendar is first displayed, if today's date is visible. The variable `number-of-diary-entries' controls the number of days of diary entries to display initially or with the command `\\[diary]'. E.g., the default value 1 means display only today's diary entries. The value 2 means display both today's and tomorrow's entries. The value of `number-of-diary-entries' can also be a vector such as \[0 2 2 2 2 4 1]. This value means: display no diary entries on Sunday, display the entries for the current day and the following day on Monday through Thursday, display Friday through Monday's entries on Friday, and display only Saturday's entries on Saturday. Set `mark-diary-entries-in-calendar' to a non-nil value to mark \(highlight), in the calendar, all the dates that have diary entries. The variable `diary-entry-marker' determines how to mark them. The variable `diary-display-hook' is the list of functions called after the diary buffer is prepared. The default value simply displays the diary file using selective-display to conceal irrelevant diary entries. An alternative function `fancy-diary-display' is provided that, when used as the `diary-display-hook', causes a noneditable buffer to be prepared with a neatly organized day-by-day listing of relevant diary entries, together with any known holidays. The inclusion of the holidays slows this fancy display of the diary. To speed it up, set the variable `holidays-in-diary-buffer' to nil. The variable `print-diary-entries-hook' is the list of functions called after a temporary buffer is prepared with the diary entries currently visible in the diary buffer. The default value of this hook adds a heading (composed from the diary buffer's mode line), does the printing with the command lpr-buffer, and kills the temporary buffer. Other uses might include, for example, rearranging the lines into order by day and time. Appointment Reminding --------------------- For information on making appointment reminders, and interfacing these with your diary, see the documentation in file `appt.el' for functions `appt-make-list', `appt-add', `appt-remind', `reminders-mode', and variables `appt-checking-p' and `view-appointments-initially'. Miscellaneous Calendar Variables and Hooks ------------------------------------------ The variable `calendar-load-hook', whose default value is nil, is a list of functions to be called when the calendar is first loaded. The variable `initial-calendar-window-hook', whose default value is nil, is list of functions to be called when the calendar window is first opened. The functions invoked are called after the calendar window is opened, but once opened is never called again. Leaving the calendar with the `q' command and reentering it will cause these functions to be called again. The variable `today-visible-calendar-hook', whose default value is nil, is the list of functions called after the \"*Calendar*\" buffer has been prepared with the calendar when today's date is visible in the window. This can be used, for example, to replace today's date with asterisks. The function `calendar-star-date' is included for this purpose: (setq today-visible-calendar-hook 'calendar-star-date) It could also be used to mark (highlight) today's date. The function `calendar-mark-today' is provided for this: (setq today-visible-calendar-hook 'calendar-mark-today) The variable `today-invisible-calendar-hook', whose default value is nil, is the list of functions called after the calendar buffer has been prepared with the calendar when doday's date is not visible in the window.

Whenever a different month is used in place of the current, the cursor is placed on the first day of that month.

Appropriate setting of the variable `view-diary-entries-initially' causes the diary entries for today's date to be displayed in another window. The value of the variable `number-of-diary-entries' controls the number of days of diary entries displayed upon initial display of the calendar. Once in the calendar window, future or past months can be moved into view. Arbitrary months can be displayed, or the calendar can be scrolled forward or backward. The cursor can be moved forward or backward by a day, a week, a month, or a year. All such commands take prefix arguments which, when negative, cause movement in the opposite direction. The digit keys \(0-9) and the minus sign (-) are automatically prefixes. The window is redisplayed as necessary to show the desired date.

If it is not visible, the hooks given by the variable `today-invisible-calendar-hook' are run instead.
