MySQL Month Function

MySQL Month function is one of the MySQL Date Functions, which returns the Month number from a given date. This MySQL Month function returns integer range from 1 to 12 where 1 = January and 12 = December.

The basic syntax of the Month Function in MySQL is as shown below:

MONTH(date or expression);

TIP: This Month function returns 0 if the user-specified date argument is 0000-00-00 or 2019-00-00. Or Say, it returns 0 if the Zero Month part is given.

MySQL Month Function Example 2

The following Date Function query shows you what happens when we try to return the month number from a date in string format.

Here, we are returning month number from the current date and time returned by the Now() function, CURDATE() function, and UTC_TIMESTAMP function.

SELECT CURDATE(), MONTH(CURDATE());

SELECT NOW(), MONTH(NOW());

SELECT UTC_TIMESTAMP(), MONTH(UTC_TIMESTAMP());

OUTPUT

Here, we are trying to return the month number from YYYYMMDD, YYMMDD formats. Within the last MySQL statement, we used the zero month part. That’s why it returns NULL.

SELECT MONTH('20160922');

SELECT MONTH('160212');

SELECT MONTH('2019-00-00'), MONTH('0');
