  • 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.
