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.
