18
19       -h, --help
20              Print help and exit
21
22       -V, --version
23              Print version and exit

30
31       -f, --format=STRING
32              Output  format.   This can either be a specifier string (similar
33              to strftime()'s FMT) or the name of a calendar.
34
35       -i, --input-format=STRING...
36              Input format, can be used multiple times.  Each  date/time  will
37              be  passed  to  the  input  format parsers in the order they are
38              given, if a date/time can be read successfully with a given  in‐
39              put format specifier string, that value will be used.

44
45       -l, --locale
46              Make internal strptime(3) and strftime(3) behave in a locale de‐
47              pendent way, default is to pretend LC_ALL=C is in place.

FORMAT SPECS

50       Format specs in dateutils are similar to posix' strftime().
51
52       However,  due  to a broader range of supported calendars dateutils must
53       employ different rules.

59         %b  The abbreviated month name
60         %B  The full month name
61         %_b The month name shortened to a single character (FGHJKMNQUVXZ)
62         %c  The count of the weekday within the month (range 00 to 05)
63         %C  The count of the weekday within the year (range 00 to 53)

126       By design dates before 1601-01-01 are not supported.
127
128       For conformity here is a list of calendar designators and their  corre‐
129       sponding format string:
130         ymd     %Y-%m-%d
131         ymcw    %Y-%m-%c-%w
132         ywd     %rY-W%V-%u
133         bizda   %Y-%m-%db
134         lilian     n/a
135         ldn        n/a
136         julian     n/a
137         jdn        n/a
138         matlab     n/a
139         mdn        n/a
140
141       These  designators  can  be  used  as  output  format string, moreover,
142       @code{lilian}/@code{ldn} and @code{julian}/@code{jdn} can also be  used
143       as input format string.
