  • 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.

    Specifier Description
    %a Abbreviated weekday name (Sun..Sat)
    %b Abbreviated month name (Jan..Dec)
    %c Month, numeric (0..12)
    %D Day of the month with English suffix (0th, 1st, 2nd, 3rd, …)
    %d Day of the month, numeric (00..31)
    %e Day of the month, numeric (0..31)
    %f Microseconds (000000..999999)
    %H Hour (00..23)
    %h Hour (01..12)
    %I Hour (01..12)
    %i Minutes, numeric (00..59)
    %j Day of year (001..366)
    %k Hour (0..23)
    %l Hour (1..12)
    %M Month name (January..December)
    %m Month, numeric (00..12)
    %p AM or PM
    %r Time, 12-hour (hh:mm:ss followed by AM or PM)
    %S Seconds (00..59)
    %s Seconds (00..59)
    %T Time, 24-hour (hh:mm:ss)
    %U Week (00..53), where Sunday is the first day of the week
    %u Week (00..53), where Monday is the first day of the week
    %V Week (01..53), where Sunday is the first day of the week; used with %X
    %v Week (01..53), where Monday is the first day of the week; used with %x
    %W Weekday name (Sunday..Saturday)
    %w Day of the week (0=Sunday..6=Saturday)
    %X Year for the week where Sunday is the first day of the week, numeric, four digits; used with %V
    %x Year for the week, where Monday is the first day of the week, numeric, four digits; used with %v
    %Y Year, numeric, four digits
    %y Year, numeric (two digits)
    %% A literal “%” character
    %x x, 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
