The list entries have the form ((month day year) string). If the variable

\(consisting of the empty string\) for a date with no diary entries.
After the list is prepared, the hooks `nongregorian-diary-listing-hook',
`list-diary-entries-hook', and `diary-display-hook' are run. These hooks
have the following distinct roles:
`nongregorian-diary-listing-hook' can cull dates from the diary
and each included file. Usually used for Hebrew or Islamic
diary entries in files. Applied to *each* file.
`list-diary-entries-hook' adds or manipulates diary entries from
external sources. Used, for example, to include diary entries
from other files or to sort the diary entries. Invoked *once* only.
`diary-display-hook' does the actual display of information. Could be
used also for an appointment notification function."

Sexp diary entries must be prefaced by a sexp-diary-entry-symbol (normally

%%(SEXP) ENTRY
Both ENTRY and DATE are globally available when the SEXP is evaluated. If the
SEXP yields the value nil, the diary entry does not apply. If it yields a
non-nil value, ENTRY will be taken to apply to DATE; if the non-nil value is a
string, that string will be the diary entry in the fancy diary display.

if it is a weekday and the Friday before if the 21st is on a weekend:

if N is negative it counts backward from the end of
the month. MONTH can be a list of months, a single
month, or t to specify all months.
%%(diary-block M1 D1 Y1 M2 D2 Y2) text
Entry will appear on dates between M1/D1/Y1 and M2/D2/Y2,
inclusive. (If `european-calendar-style' is t, the
order of the parameters should be changed to D1, M1, Y1,
D2, M2, Y2.)
%%(diary-anniversary MONTH DAY YEAR) text
Entry will appear on anniversary dates of MONTH DAY, YEAR.
(If `european-calendar-style' is t, the order of the
parameters should be changed to DAY, MONTH, YEAR.) Text
can contain %d or %d%s; %d will be replaced by the number
of years since the MONTH DAY, YEAR and %s will be replaced
by the ordinal ending of that number (that is, `st', `nd',
`rd' or `th', as appropriate. The anniversary of February
29 is considered to be March 1 in a non-leap year.
%%(diary-cyclic N MONTH DAY YEAR) text
Entry will appear every N days, starting MONTH DAY, YEAR.
(If `european-calendar-style' is t, the order of the
parameters should be changed to N, DAY, MONTH, YEAR.) Text
can contain %d or %d%s; %d will be replaced by the number
of repetitions since the MONTH DAY, YEAR and %s will
be replaced by the ordinal ending of that number (that is,
`st', `nd', `rd' or `th', as appropriate.
%%(diary-day-of-year)
Diary entries giving the day of the year and the number of
days remaining in the year will be made every day. Note
that since there is no text, it makes sense only if the
fancy diary display is used.
%%(diary-iso-date)
Diary entries giving the corresponding ISO commercial date
will be made every day. Note that since there is no text,
it makes sense only if the fancy diary display is used.
%%(diary-french-date)
Diary entries giving the corresponding French Revolutionary
date will be made every day. Note that since there is no
text, it makes sense only if the fancy diary display is used.
%%(diary-islamic-date)
Diary entries giving the corresponding Islamic date will be
made every day. Note that since there is no text, it
makes sense only if the fancy diary display is used.
%%(diary-hebrew-date)
Diary entries giving the corresponding Hebrew date will be
made every day. Note that since there is no text, it
makes sense only if the fancy diary display is used.
%%(diary-yahrzeit MONTH DAY YEAR) text
Text is assumed to be the name of the person; the date is
the date of death on the *civil* calendar. The diary entry
will appear on the proper Hebrew-date anniversary and on the
day before. (If `european-calendar-style' is t, the order
of the parameters should be changed to DAY, MONTH, YEAR.)
%%(diary-rosh-hodesh)
Diary entries will be made on the dates of Rosh Hodesh on
the Hebrew calendar. Note that since there is no text, it
makes sense only if the fancy diary display is used.
%%(diary-parasha)
Diary entries giving the weekly parasha will be made on
every Saturday. Note that since there is no text, it
makes sense only if the fancy diary display is used.
%%(diary-omer)
Diary entries giving the omer count will be made every day
from Passover to Shavuoth. Note that since there is no text,
it makes sense only if the fancy diary display is used.
