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'
