Difference Between DATE, DATETIME and TIMESTAMP data types

The DATE type is used for values with a date part but no time part. MySQL retrieves and displays DATE values in ‘YYYY-MM-DD’ format. The supported range is ‘1000-01-01’ to ‘9999-12-31’.

The DATETIME type is used for values that contain both date and time parts. MySQL retrieves and displays DATETIME values in ‘YYYY-MM-DD HH:MM:SS’ format. The supported range is ‘1000-01-01 00:00:00’ to ‘9999-12-31 23:59:59’.

The TIMESTAMP data type is used for values that contain both date and time parts. TIMESTAMP has a range of ‘1970-01-01 00:00:01’ UTC to ‘2038-01-19 03:14:07’ UTC.

A major difference between these three data types is that TIMESTAMP data type values are converted from current time zone to UTC for storage purpose and converted back from UTC to current time zone when used. The datetime and date data type values are unchanged in relation to time zone.
