PARAMETERS         top

       Single digits-only parameter (e.g. 'cal 2020')
              Specifies the year to be displayed; note the year must be
              fully specified: cal 89 will not display a calendar for 1989.

       Single string parameter (e.g. 'cal tomorrow' or 'cal August')
              Specifies timestamp or a month name (or abbreviated name)
              according to the current locales.

              The special placeholders are accepted when parsing timestamp,
              "now" may be used to refer to the current time, "today",
              "yesterday", "tomorrow" refer to of the current day, the day
              before or the next day, respectively.

              The relative date specifications are also accepted, in this
              case "+" is evaluated to the current time plus the specified
              time span. Correspondingly, a time span that is prefixed with
              "-" is evaluated to the current time minus the specified time
              span, for example '+2days'. Instead of prefixing the time span
              with "+" or "-", it may also be suffixed with a space and the
              word "left" or "ago" (for example '1 week ago').

       Two parameters (e.g. 'cal 11 2020')
              Denote the month (1 - 12) and year.

       Three parameters (e.g. 'cal 25 11 2020')
              Denote the day (1-31), month and year, and the day will be
              highlighted if the calendar is displayed on a terminal.  If no
              parameters are specified, the current month's calendar is

NOTES         top

       A year starts on January 1.  The first day of the week is determined
       by the locale.

       The week numbering depends on the choice of the first day of the
       week.  If Sunday (the default) is used for the first day of the week,
       then the customary North American numbering will be used, i.e. the
       first Sunday of the year starts the first week.  If Monday is
       selected, then the ISO-8601 standard week numbering is used, where
       the first Thursday of the year is in week number 1.

COLORS         top

       Implicit coloring can be disabled as follows:

              touch /etc/terminal-colors.d/cal.disable

       See terminal-colors.d(5) for more details about colorization

BUGS         top

       The cal program uses the 3rd of September 1752 as the date of the
       Gregorian calendar reformation -- that is when it happened in Great
       Britain and its colonies (including what is now the USA).  Starting
       at that date, eleven days were eliminated by this reformation, so the
       calendar for that month is rather unusual.  The actual historical
       dates at which the calendar reform happened in all the different
       countries (locales) are ignored.

       Alternative calendars, such as the Umm al-Qura, the Solar Hijri, the
       Ge'ez, or the lunisolar Hindu, are not supported.
