4 .SH NAME
5 ddate \- converts Gregorian dates to Discordian dates
6 .SH SYNOPSIS
7 .B ddate [+format] [date]
8 .SH DESCRIPTION
9 .B ddate
10 prints the date in Discordian date format.
11 .PP
12 If called with no arguments,
13 .B ddate
14 will get the current system date, convert this to the Discordian
15 date format and print this on the standard output. Alternatively, a
16 Gregorian date may be specified on the command line, in the form of a numerical
17 day, month and year.
18 .PP
19 If a format string is specified, the Discordian date will be printed in
20 a format specified by the string. This mechanism works similarly to the
21 format string mechanism of
22 .B date(1),
23 only almost completely differently. The fields are:
24 .IP %A
25 Full name of the day of the week (i.e., Sweetmorn)
26 .IP %a
27 Abbreviated name of the day of the week (i.e., SM)
28 .IP %B
29 Full name of the season (i.e., Chaos)
30 .IP %b
31 Abbreviated name of the season (i.e., Chs)
32 .IP %d
33 Ordinal number of day in season (i.e., 23)
34 .IP %e
35 Cardinal number of day in season (i.e., 23rd)
36 .IP %H
37 Name of current Holyday, if any
38 .IP %N
39 Magic code to prevent rest of format from being printed unless today is
40 a Holyday.
41 .IP %n
42 Newline
43 .IP %t
44 Tab
45 .IP %X
46 Number of days remaining until X-Day. (Not valid if the SubGenius options
47 are not compiled in.)
48 .IP %{
49 .IP %}
50 Used to enclose the part of the string which is to be replaced with the
51 words "St. Tib's Day" if the current day is St. Tib's Day.
52 .IP %\.
53 Try it and see.

75
76 .SH BUGS
77
78 .B ddate(1)
79 will produce undefined behaviour if asked to produce the date for St. Tib's
80 day and its format string does not contain the St. Tib's Day delimiters
81 %{ and %}.
82
83 .SH NOTE
84
85 After `X-Day' passed without incident, the Church of the SubGenius
86 declared that it had got the year upside down - X-Day is actually in 8661 AD
87 rather than 1998 AD. Thus, the True X-Day is Cfn 40, 9827.
