From one timestamp to another

Measure the exact span between two moments, down to minutes. For shifts, downtime reports and elapsed-time questions.

When a span crosses midnight, arithmetic stops being obvious. A shift from 22:00 to 06:00 is eight hours, but subtracting the numbers gives you minus sixteen.

Giving both a date and a time removes the ambiguity, so overnight shifts and multi-day incidents come out right.

What this calculator shows

The exact span in days, hours and minutes
Correct handling of spans that cross midnight
The same duration expressed in total hours and total minutes

What to keep in mind

Both moments are treated as being in the same timezone.
Daylight saving transitions can make a calendar day 23 or 25 hours long.

FAQs

How do I calculate hours across midnight?

Give both the date and the time for each end. The tool then measures a real interval rather than subtracting two clock faces.

Does daylight saving affect the result?

It can. A day containing a clock change is 23 or 25 hours long, which is exactly why payroll for that night needs checking.

Can I get the answer in minutes?

Yes, the total is shown in minutes as well as the days-hours-minutes breakdown — useful for billing.

What if I put the later date first?

The tool reports the magnitude of the gap, so swapping them does not produce a broken negative result.

Worked example

A night shift

Input: 22:00 on 1 March to 06:00 on 2 March

Output: 8 hours

Note: Naive subtraction of clock times gives −16 hours. Including the date is what makes the answer sensible.
