623 using selective display. If NUMBER is less than 1, this function does nothing.
625 Returns a list of all relevant diary entries found, if any, in order by date.
626 The list entries have the form ((MONTH DAY YEAR) STRING SPECIFIER) where
627 \(MONTH DAY YEAR) is the date of the entry, STRING is the entry text, and
628 SPECIFIER is the applicability. If the variable `diary-list-include-blanks'
629 is t, this list includes a dummy diary entry consisting of the empty string
630 for a date with no diary entries.
632 After the list is prepared, the hooks `nongregorian-diary-listing-hook',
633 `list-diary-entries-hook', `diary-display-hook', and `diary-hook' are run.
634 These hooks have the following distinct roles:
636 `nongregorian-diary-listing-hook' can cull dates from the diary
637 and each included file. Usually used for Hebrew or Islamic
638 diary entries in files. Applied to *each* file.
640 `list-diary-entries-hook' adds or manipulates diary entries from
641 external sources. Used, for example, to include diary entries
642 from other files or to sort the diary entries. Invoked *once* only,
643 before the display hook is run.
645 `diary-display-hook' does the actual display of information. If this is
646 nil, simple-diary-display will be used. Use add-hook to set this to
647 fancy-diary-display, if desired. If you want no diary display, use
648 add-hook to set this to ignore.
650 `diary-hook' is run last. This can be used for an appointment
651 notification function.

1484 `european-calendar-style' is t. DAY, MONTH, and YEAR
1485 can be lists of integers, the constant t, or an integer.
1486 The constant t means all values. An optional parameter
1487 MARK specifies a face or single-character string to use
1488 when highlighting the day in the calendar.
1490 %%(diary-float MONTH DAYNAME N &optional DAY MARK) text
1491 Entry will appear on the Nth DAYNAME of MONTH.
1492 (DAYNAME=0 means Sunday, 1 means Monday, and so on;
1493 if N is negative it counts backward from the end of
1494 the month. MONTH can be a list of months, a single
1495 month, or t to specify all months. Optional DAY means
1496 Nth DAYNAME of MONTH on or after/before DAY. DAY defaults
1497 to 1 if N>0 and the last day of the month if N<0. An
1498 optional parameter MARK specifies a face or single-character
1499 string to use when highlighting the day in the calendar.
1501 %%(diary-block M1 D1 Y1 M2 D2 Y2 &optional MARK) text
1502 Entry will appear on dates between M1/D1/Y1 and M2/D2/Y2,
1503 inclusive. (If `european-calendar-style' is t, the
1504 order of the parameters should be changed to D1, M1, Y1,
1505 D2, M2, Y2.) An optional parameter MARK specifies a face
1506 or single-character string to use when highlighting the
1507 day in the calendar.
1509 %%(diary-anniversary MONTH DAY YEAR &optional MARK) text
1510 Entry will appear on anniversary dates of MONTH DAY, YEAR.
1511 (If `european-calendar-style' is t, the order of the
1512 parameters should be changed to DAY, MONTH, YEAR.) Text
1513 can contain %d or %d%s; %d will be replaced by the number
1514 of years since the MONTH DAY, YEAR and %s will be replaced
1515 by the ordinal ending of that number (that is, `st', `nd',
1516 `rd' or `th', as appropriate. The anniversary of February
1517 29 is considered to be March 1 in a non-leap year. An
1518 optional parameter MARK specifies a face or single-character
1519 string to use when highlighting the day in the calendar.
1521 %%(diary-cyclic N MONTH DAY YEAR &optional MARK) text
1522 Entry will appear every N days, starting MONTH DAY, YEAR.
1523 (If `european-calendar-style' is t, the order of the
1524 parameters should be changed to N, DAY, MONTH, YEAR.) Text
1525 can contain %d or %d%s; %d will be replaced by the number
1526 of repetitions since the MONTH DAY, YEAR and %s will
1527 be replaced by the ordinal ending of that number (that is,
1528 `st', `nd', `rd' or `th', as appropriate. An optional
1529 parameter MARK specifies a face or single-character string
1530 to use when highlighting the day in the calendar.
1532 %%(diary-remind SEXP DAYS &optional MARKING) text
1533 Entry is a reminder for diary sexp SEXP. DAYS is either a
1534 single number or a list of numbers indicating the number(s)
1535 of days before the event that the warning(s) should occur.
1536 If the current date is (one of) DAYS before the event
1537 indicated by EXPR, then a suitable message (as specified
1538 by `diary-remind-message') appears. In addition to the
1539 reminders beforehand, the diary entry also appears on
1540 the date itself. If optional MARKING is non-nil then the
1541 *reminders* are marked on the calendar. Marking of
1542 reminders is independent of whether the entry *itself* is
1543 a marking or nonmarking one.
1545 %%(diary-day-of-year)
1546 Diary entries giving the day of the year and the number of
1547 days remaining in the year will be made every day. Note

1595 the date of death on the *civil* calendar. The diary entry
1596 will appear on the proper Hebrew-date anniversary and on the
1597 day before. (If `european-calendar-style' is t, the order
1598 of the parameters should be changed to DAY, MONTH, YEAR.)

1601 Diary entries will be made on the dates of Rosh Hodesh on
1602 the Hebrew calendar. Note that since there is no text, it
1603 makes sense only if the fancy diary display is used.

1607 every Saturday. Note that since there is no text, it
1608 makes sense only if the fancy diary display is used.
