Explanation: To subtract time, subtract the minutes then subtract the hours. Since we can't have negative minutes, add 60 to the minutes and subtract 1 from the hours (60 minutes = 1 hour).

You can simply use datetime diff and format for calculating difference. <? php $datetime1 = new DateTime('2009-10-11 12:12:00'); $datetime2 = new DateTime('2009-10-13 10:12:00'); $interval = $datetime1->diff($datetime2); echo $interval->format('%Y-%m-%d %H:%i:%s'); ?>

Sub() to get the difference between two time. Time values, the result that we get is time. Duration which is an float64. If you want the result in minutes or hours, you can use Minutes() or Hours() instead of Seconds().

Finding the number of hours or the time between two times / dates is simple, just subtract the start date/time from the end date/time and multiply the result by 24 hours.

Finding the number of hours or the time between two times / dates is simple, just subtract the start date/time from the end date/time and multiply the result by 24 hours. If you want to enter the dates and times separately (which is loads easier than typing in a date/time in one cell) then add the date/times together.

diff = t2 - t1. seconds = diff MOD 86400. hours = seconds / 3600. The number of hours between 02:00:00 and 20:00:00 is calculated.

Total minutes between two times: To calculate the minutes between two times, multiply the time difference by 1440, which is the number of minutes in one day (24 hours * 60 minutes = 1440).

Date difference with Moment objects You can also create Moment objects and then calculate the difference: var admission = moment('{date1}', 'DD-MM-YYYY'); var discharge = moment('{date2}', 'DD-MM-YYYY'); discharge.

These SQL queries computes the time difference using first the seconds (multiplied by one hour in seconds is 60 * 60 = 3600. Then using the milliseconds (multiplied by one hour in milliseconds as 60 * 60 * 1000 = 3600 * 1000 ).
