FORMAT SPECS


Format specs in dateutils are similar to posix' strftime().

However, due to a broader range of supported calendars dateutils must employ different
rules.

Date specs:
%a The abbreviated weekday name
%A The full weekday name
%_a The weekday name shortened to a single character (MTWRFAS)
%b The abbreviated month name
%B The full month name
%_b The month name shortened to a single character (FGHJKMNQUVXZ)
%c The count of the weekday within the month (range 00 to 05)
%C The count of the weekday within the year (range 00 to 53)
%d The day of the month, 2 digits (range 00 to 31)
%D The day of the year, 3 digits (range 000 to 366)
%F Equivalent to %Y-%m-%d (ymd's canonical format)
%j Equivalent to %D
%m The month in the current calendar (range 00 to 19)
%Q The quarter of the year (range Q1 to Q4)
%q The number of the quarter (range 01 to 04)
%s The number of seconds since the Epoch.
%u The weekday as number (range 01 to 07, Sunday being 07)
%U The week count, day of week is Sun (range 00 to 53)
%V The ISO week count, day of week is Mon (range 01 to 53)
%w The weekday as number (range 00 to 06, Sunday being 00)
%W The week count, day of week is Mon (range 00 to 53)
%y The year without a century (range 00 to 99)
%Y The year including the century
%Z The zone offset in hours and minutes (HH:MM) with
a preceding sign (+ for offsets east of UTC, - for offsets
west of UTC)

%Od The day as roman numerals
%Om The month as roman numerals
%Oy The two digit year as roman numerals
%OY The year including the century as roman numerals

%rs In time systems whose Epoch is different from the unix Epoch, this
selects the number of seconds since then.
%rY In calendars with years that don't coincide with the Gregorian
years, this selects the calendar's year.

%dth The day of the month as an ordinal number, 1st, 2nd, 3rd, etc.
%mth The month of the year as an ordinal number, 1st, 2nd, 3rd, etc.

%db The business day of the month (since last month's ultimo)
%dB Number of business days until this month's ultimo

Time specs:
%H The hour of the day using a 24h clock, 2 digits (range 00 to 23)
%I The hour of the day using a 12h clock, 2 digits (range 01 to 12)
%M The minute (range 00 to 59)
%N The nanoseconds (range 000000000 to 999999999)
%p The string AM or PM, noon is PM and midnight is AM.
%P Like %p but in lowercase
%S The (range 00 to 60, 60 is for leap seconds)
%T Equivalent to %H:%M:%S

General specs:
%n A newline character
%t A tab character
%% A literal % character

Modifiers:
%O Modifier to turn decimal numbers into Roman numerals
%r Modifier to turn units into real units
th Suffix, read and print ordinal numbers
b Suffix, treat days as business days

By design dates before 1601-01-01 are not supported.

For conformity here is a list of calendar designators and their corresponding format
string:
ymd %Y-%m-%d
ymcw %Y-%m-%c-%w
ywd %rY-W%V-%u
bizda %Y-%m-%db
lilian n/a
ldn n/a
julian n/a
jdn n/a

These designators can be used as output format string, moreover, @code{lilian}/@code{ldn}
and @code{julian}/@code{jdn} can also be used as input format string.
