diary-cyclic

diary-cyclic is a compiled Lisp function in `diary-lib.el'.

(diary-cyclic N MONTH DAY YEAR &optional MARK)

Cycle diary entry--entry applies every N days starting at MONTH, DAY, YEAR.
The order of the input parameters changes according to
`calendar-date-style' (e.g. to N DAY MONTH YEAR in the European
style). The entry can contain `%d' or `%d%s'; the %d will be
replaced by the number of repetitions since the MONTH DAY YEAR,
and %s by the ordinal ending of that number (that is, `st', `nd',
`rd' or `th', as appropriate).

An optional parameter MARK specifies a face or single-character
string to use when highlighting the day in the calendar.
