If called with no arguments, ddate will get the current system date, convert this to the Discordian date format and print this on the standard output. Alternatively, a Gregorian date may be specified on the command line, in the form of a numerical day, month and year.
If a format string is specified, the Discordian date will be printed in a format specified by the string. This mechanism works similarly to the format string mechanism of date(1), only almost completely differently. The fields are:
% ddate
Sweetmorn, Bureaucracy 42, 3161 YOLD % ddate +'Today is %{%A, the %e of %B%}, %Y. %N%nCelebrate %H'
Today is Sweetmorn, the 42nd of Bureaucracy, 3161. % ddate +"It's %{%A, the %e of %B%}, %Y. %N%nCelebrate %H" 26 9 1995
It's Prickle-Prickle, the 50th of Bureaucracy, 3161.
Celebrate Bureflux % ddate +"Today's %{%A, the %e of %B%}, %Y. %N%nCelebrate %H" 29 2 1996
Today's St. Tib's Day, 3162.
ddate(1) will produce undefined behaviour if asked to produce the date for St. Tib's day and its format string does not contain the St. Tib's Day delimiters %{ and %}.
After `X-Day' passed without incident, the Church of the SubGenius declared that it had got the year upside down - X-Day is actually in 8661 AD rather than 1998 AD. Thus, the True X-Day is Cfn 40, 9827.
