Subtracts the 2nd argument from the 3rd (date2 − date1). I just want the difference between the two timestamps in in hours represented by an INT. I am facing a little confusion because of CURRENT_DATE value and CURRENT_TIMESTAMP value shows different date on MySQL. select id, CAST (datediff (curdate (),birth_date) / 365 as int) from student. Select TIMESTAMPDIFF( YEAR, startdate, now() ) as _year ,TIMESTAMPDIFF( MONTH, startdate, now() ) % 12 as _month ,FLOOR( TIMESTAMPDIFF( DAY, startdate, now() ) % 30.
