DAYEXPR(1)

     NAME
          dayexpr - Do ClearDDTS date arithmetic

     SYNOPSIS
          dayexpr yymmdd - yymmdd
          dayexpr yymmdd + n
          dayexpr yymmdd - n

     DESCRIPTION
          Use dayexpr to do date arithmetic in ClearDDTS format.

          ClearDDTS records dates as yymmdd where yy is the last two
          digits of the year, mm is a two-digit month number (1-12),
          and dd is a two-digit day of the month.

          The first parameter must be a date in ClearDDTS format.  The
          second parameter must be a `+' or a `-'.  The last parameter
          can be either another date to be subtracted from the first
          date, or a number (of fewer than six digits) specifying the
          number of days to add or subtract from the first date.
