219 and each included file. Usually used for Hebrew or Islamic
220 diary entries in files. Applied to *each* file.
222 `list-diary-entries-hook' adds or manipulates diary entries from
223 external sources. Used, for example, to include diary entries
224 from other files or to sort the diary entries. Invoked *once* only,
225 before the display hook is run.
227 `diary-display-hook' does the actual display of information. If this is
228 nil, simple-diary-display will be used. Use add-hook to set this to
229 fancy-diary-display, if desired. If you want no diary display, use
230 add-hook to set this to ignore.
232 `diary-hook' is run last. This can be used for an appointment

1014 `european-calendar-style' is t. DAY, MONTH, and YEAR
1015 can be lists of integers, the constant t, or an integer.
1016 The constant t means all values.
1018 %%(diary-float MONTH DAYNAME N &optional DAY) text
1019 Entry will appear on the Nth DAYNAME of MONTH.
1020 (DAYNAME=0 means Sunday, 1 means Monday, and so on;
1021 if N is negative it counts backward from the end of
1022 the month. MONTH can be a list of months, a single
1023 month, or t to specify all months. Optional DAY means
1024 Nth DAYNAME of MONTH on or after/before DAY. DAY defaults
1025 to 1 if N>0 and the last day of the month if N<0.
1027 %%(diary-block M1 D1 Y1 M2 D2 Y2) text
1028 Entry will appear on dates between M1/D1/Y1 and M2/D2/Y2,
1029 inclusive. (If `european-calendar-style' is t, the
1030 order of the parameters should be changed to D1, M1, Y1,

1035 (If `european-calendar-style' is t, the order of the

1037 can contain %d or %d%s; %d will be replaced by the number

1040 `rd' or `th', as appropriate. The anniversary of February
1041 29 is considered to be March 1 in a non-leap year.

1044 Entry will appear every N days, starting MONTH DAY, YEAR.
1045 (If `european-calendar-style' is t, the order of the
1046 parameters should be changed to N, DAY, MONTH, YEAR.) Text

1050 `st', `nd', `rd' or `th', as appropriate.
1052 %%(diary-remind SEXP DAYS &optional MARKING) text
1053 Entry is a reminder for diary sexp SEXP. DAYS is either a
1054 single number or a list of numbers indicating the number(s)
1055 of days before the event that the warning(s) should occur.
1056 If the current date is (one of) DAYS before the event
1057 indicated by EXPR, then a suitable message (as specified
1058 by `diary-remind-message') appears. In addition to the
1059 reminders beforehand, the diary entry also appears on
1060 the date itself. If optional MARKING is non-nil then the
1061 *reminders* are marked on the calendar. Marking of
1062 reminders is independent of whether the entry *itself* is
1063 a marking or nonmarking one.
1065 %%(diary-day-of-year)

1067 days remaining in the year will be made every day. Note

1115 the date of death on the *civil* calendar. The diary entry
1116 will appear on the proper Hebrew-date anniversary and on the
1117 day before. (If `european-calendar-style' is t, the order
