+.TH DDATE 1 "Bureaucracy 3161" "ddate" "Emperor Norton User Command"
+.SH NAME
+ddate \- convert Gregorian dates to Discordian dates
+.SH SYNOPSIS
+.B ddate
+.RI [ \fB+\fPformat]
+.RI [ date ]
+.SH DESCRIPTION
+.B ddate
+prints the date in Discordian date format.
+.PP
+If called with no arguments,
+.B 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.
+.PP
+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
+.B date(1),
+only almost completely differently. The fields are:
+.IP %A
+Full name of the day of the week (i.e., Sweetmorn)
+.IP %a
+Abbreviated name of the day of the week (i.e., SM)
+.IP %B
+Full name of the season (i.e., Chaos)
+.IP %b
+Abbreviated name of the season (i.e., Chs)
+.IP %d
+Cardinal number of day in season (i.e., 23)
+.IP %e
+Ordinal number of day in season (i.e., 23rd)
+.IP %H
+Name of current Holyday, if any
+.IP %N
+Magic code to prevent rest of format from being printed unless today is
+a Holyday.
+.IP %n
+Newline
+.IP %t
+Tab
+.IP %X
+Number of days remaining until X-Day. (Not valid if the SubGenius options
+are not compiled in.)
+.IP %Y
+The year of our Lady Discord (i.e., 3182)
+.IP %{
+.IP %}
+Used to enclose the part of the string which is to be replaced with the
+words "St. Tib's Day" if the current day is St. Tib's Day.
+.IP %\.
+Try it and see.

+% ddate
+.br
+Sweetmorn, Bureaucracy 42, 3161 YOLD
+.PP
+% ddate +'Today is %{%A, the %e of %B%}, %Y. %N%nCelebrate %H'
+.br
+Today is Sweetmorn, the 42nd of Bureaucracy, 3161.
+.PP
+% ddate +"It's %{%A, the %e of %B%}, %Y. %N%nCelebrate %H" 26 9 1995
+.br
+It's Prickle-Prickle, the 50th of Bureaucracy, 3161.
+.br
+Celebrate Bureflux
+.PP
+% ddate +"Today's %{%A, the %e of %B%}, %Y. %N%nCelebrate %H" 29 2 1996
+.br
+Today's St. Tib's Day, 3162.
+.br
+
+.SH BUGS
+
+.B ddate(1)
+will produce undefined behavior 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 %}.
+
+.SH NOTE
+
+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.
