  • DATE_FORMAT(date,format)

    Formats the date value according to the format string.

    The following specifiers may be used in the format string. As of MySQL 3.23, the “%” character is required before format specifier characters. In earlier versions of MySQL, “%” was optional.

    SpecifierDescription
    %aAbbreviated weekday name (Sun..Sat)
    %bAbbreviated month name (Jan..Dec)
    %cMonth, numeric (0..12)
    %DDay of the month with English suffix (0th, 1st, 2nd, 3rd, …)
    %dDay of the month, numeric (00..31)
    %eDay of the month, numeric (0..31)
    %fMicroseconds (000000..999999)
    %HHour (00..23)
    %hHour (01..12)
    %IHour (01..12)
    %iMinutes, numeric (00..59)
    %jDay of year (001..366)
    %kHour (0..23)
    %lHour (1..12)
    %MMonth name (January..December)
    %mMonth, numeric (00..12)
    %pAM or PM
    %rTime, 12-hour (hh:mm:ss followed by AM or PM)
    %SSeconds (00..59)
    %sSeconds (00..59)
    %TTime, 24-hour (hh:mm:ss)
    %UWeek (00..53), where Sunday is the first day of the week
    %uWeek (00..53), where Monday is the first day of the week
    %VWeek (01..53), where Sunday is the first day of the week; used with %X
    %vWeek (01..53), where Monday is the first day of the week; used with %x
    %WWeekday name (Sunday..Saturday)
    %wDay of the week (0=Sunday..6=Saturday)
    %XYear for the week where Sunday is the first day of the week, numeric, four digits; used with %V
    %xYear for the week, where Monday is the first day of the week, numeric, four digits; used with %v
    %YYear, numeric, four digits
    %yYear, numeric (two digits)
    %%A literal “%” character
    %xx, for any “x” not listed above

    The %v, %V, %x, and %X format specifiers are available as of MySQL 3.23.8. %f is available as of MySQL 4.1.1.

    Ranges for the month and day specifiers begin with zero due to the fact that MySQL permits the storing of incomplete dates such as '2014-00-00' (as of MySQL 3.23).

    As of MySQL 4.1.21, the language used for day and month names and abbreviations is controlled by the value of the lc_time_names system variable (Section 9.8, “MySQL Server Locale Support”).

    As of MySQL 4.1.23, DATE_FORMAT() returns a string with a character set and collation given by character_set_connection and collation_connection so that it can return month and weekday names containing non-ASCII characters. Before 4.1.23, the return value is a binary string.

    mysql> SELECT DATE_FORMAT('2009-10-04 22:23:00', '%W %M %Y');    -> 'Sunday October 2009'mysql> SELECT DATE_FORMAT('2007-10-04 22:23:00', '%H:%i:%s');    -> '22:23:00'mysql> SELECT DATE_FORMAT('1900-10-04 22:23:00',  ->         '%D %y %a %d %m %b %j');    -> '4th 00 Thu 04 10 Oct 277'mysql> SELECT DATE_FORMAT('1997-10-04 22:23:00',  ->         '%H %k %I %r %T %S %w');    -> '22 22 10 10:23:00 PM 22:23:00 00 6'mysql> SELECT DATE_FORMAT('1999-01-01', '%X %V');    -> '1998 52'mysql> SELECT DATE_FORMAT('2006-06-00', '%d');    -> '00'
