coreutils: Date conversion specifiers

 
 21.1.2 Date conversion specifiers
 ---------------------------------
 
 ‘date’ conversion specifiers related to dates.
 
 ‘%a’
      locale’s abbreviated weekday name (e.g., ‘Sun’)
 ‘%A’
      locale’s full weekday name, variable length (e.g., ‘Sunday’)
 ‘%b’
      locale’s abbreviated month name (e.g., ‘Jan’)
 ‘%B’
      locale’s full month name, variable length (e.g., ‘January’)
 ‘%c’
      locale’s date and time (e.g., ‘Thu Mar  3 23:05:25 2005’)
 ‘%C’
      century.  This is like ‘%Y’, except the last two digits are
      omitted.  For example, it is ‘20’ if ‘%Y’ is ‘2000’, and is ‘-0’ if
      ‘%Y’ is ‘-001’.  It is normally at least two characters, but it may
      be more.
 ‘%d’
      day of month (e.g., ‘01’)
 ‘%D’
      date; same as ‘%m/%d/%y’
 ‘%e’
      day of month, space padded; same as ‘%_d’
 ‘%F’
      full date in ISO 8601 format; like ‘%+4Y-%m-%d’ except that any
      flags or field width override the ‘+’ and (after subtracting 6) the
      ‘4’.  This is a good choice for a date format, as it is standard
      and is easy to sort in the usual case where years are in the range
      0000...9999.
 ‘%g’
      year corresponding to the ISO week number, but without the century
      (range ‘00’ through ‘99’).  This has the same format and value as
      ‘%y’, except that if the ISO week number (see ‘%V’) belongs to the
      previous or next year, that year is used instead.
 ‘%G’
      year corresponding to the ISO week number.  This has the same
      format and value as ‘%Y’, except that if the ISO week number (see
      ‘%V’) belongs to the previous or next year, that year is used
      instead.  It is normally useful only if ‘%V’ is also used; for
      example, the format ‘%G-%m-%d’ is probably a mistake, since it
      combines the ISO week number year with the conventional month and
      day.
 ‘%h’
      same as ‘%b’
 ‘%j’
      day of year (‘001’...‘366’)
 ‘%m’
      month (‘01’...‘12’)
 ‘%q’
      quarter of year (‘1’...‘4’)
 ‘%u’
      day of week (‘1’...‘7’) with ‘1’ corresponding to Monday
 ‘%U’
      week number of year, with Sunday as the first day of the week
      (‘00’...‘53’).  Days in a new year preceding the first Sunday are
      in week zero.
 ‘%V’
      ISO week number, that is, the week number of year, with Monday as
      the first day of the week (‘01’...‘53’).  If the week containing
      January 1 has four or more days in the new year, then it is
      considered week 1; otherwise, it is week 53 of the previous year,
      and the next week is week 1.  (See the ISO 8601 standard.)
 ‘%w’
      day of week (‘0’...‘6’) with 0 corresponding to Sunday
 ‘%W’
      week number of year, with Monday as first day of week
      (‘00’...‘53’).  Days in a new year preceding the first Monday are
      in week zero.
 ‘%x’
      locale’s date representation (e.g., ‘12/31/99’)
 ‘%y’
      last two digits of year (‘00’...‘99’)
 ‘%Y’
      year.  This is normally at least four characters, but it may be
      more.  Year ‘0000’ precedes year ‘0001’, and year ‘-001’ precedes
      year ‘0000’.
