Date & Time Difference Calculator (End − Start)

Enter a start and end date-time to see the gap as days, hours and minutes. Total days, total hours and total minutes are shown at the same time.

Input

Start date & time

Start date

YYYY/MM/DD

Start time

End date & time

End date

YYYY/MM/DD

End time

Enter both the start and end date & time.

Once you fill in both the start and end date-time (date and time), the difference is calculated automatically. Leaving any field blank means no result is shown.
The main result is shown as a days / hours / minutes breakdown, with the total also converted to days, hours and minutes.
Total hours and total days are shown to two decimal places, and total minutes as a whole number. For example, 1 hour 30 minutes is treated as 1.5 hours or 90 minutes.
Even when the end date-time is earlier than the start, the absolute (positive) value of the difference is calculated and a note about the reversed order is shown.
Useful for adding up time that spans across dates, such as work hours, task durations or the time remaining until an event begins.
