week
Return the week
Arguments
This function returns the number of the week of the year in the specified date expression as a number between 1 and 53.
The data type DATE assumes the Gregorian calendar even for dates prior to the introduction of the Gregorian calendar. This means that databases that store historical dates prior to the introduction of the Gregorian calendar may not compute SELECT with date ranges, DAYOFWEEK, and WEEK correctly.
Example
select week(curdate()) as "Current Week"; Current Week 16
