In this article, we would like to show you the difference between DATE, TIME, DATETIME and TIMESTAMP types in MySQL.

1. DATE

The DATE type is used for values with a date part but no time part in YYYY-MM-DD format, where:

  • YYYY - four-digit¬†year format, e.g. 2021,
  • MM - month number (counted from 01 to 12),
  • DD -¬†day number (from 01¬†to 31 - depending on the month)

The DATE type supported range is from 1000-01-01 to 9999-12-31.

Example DATE:

2021-01-01

2. TIME

The TIME type is used for values with time part in hh:mm:ss format, where:

  • hh¬†- hour number (from 00 to 24),
  • mm - minute number (from 00 to 59),
  • ss - second number¬†(from 00 to 59).

Example TIME:

11:15:59

3. DATETIME

The DATETIME type is used for values that contain both date and time parts in YYYY-MM-DD hh:mm:ss format, where:

  • YYYY - four-digit¬†year format, e.g. 2021,
  • MM - month number (counted from 01 to 12),
  • DD -¬†day number (from 01¬†to 31 - depending on the month),
  • hh¬†- hour number (from 00 to 24),
  • mm - minute number (from 00 to 59),
  • ss - second number¬†(from 00 to 59).

The supported range is from 1000-01-01 00:00:00 to 9999-12-31 23:59:59.

Example DATETIME:

2021-10-21 11:55:44

4. TIMESTAMP

The TIMESTAMP type is used for values that contain both date and time parts in YYYY-MM-DD hh:mm:ss format, where:

  • YYYY - four-digit¬†year format, e.g. 2021,
  • MM - month number (counted from 01 to 12),
  • DD -¬†day number (from 01¬†to 31 - depending on the month),
  • hh¬†- hour number (from 00 to 24),
  • mm - minute number (from 00 to 59),
  • ss - second number¬†(from 00 to 59).

The TIMESTAMP has a range of 1970-01-01 00:00:01 UTC to 2038-01-19 03:14:07 UTC.
