How Many Hours Between Two Times

Calculate elapsed time between two times, in hours and minutes, total minutes, and decimal hours. Add a break or span multiple days.

How do you calculate hours and minutes between two times?

To calculate the hours between two times, subtract the start time from the end time. If the end time is on the next day, add 24 hours before subtracting. To convert to decimal hours, divide the total minutes by 60. The calculator below handles overnight shifts and break deductions automatically.

Result

Hours & minutes: 8h 0m
Decimal hours: 8.00
Total minutes: 480

Duration: 8h 0m (8.00 hours, 480 minutes), break of 30 min deducted.

How to calculate hours between two times

Enter the start time in 24-hour format (e.g. 09:00).
Enter the end time (e.g. 17:30).
If the end is on the next day, turn on End time is next day or fill in both dates.
Optional: add a break in hours and minutes to subtract from the total.
Read the duration in hours and minutes, decimal hours, and total minutes.

Example

From 09:00 to 17:30 with a 30-minute break is 8h 0m (8.00 hours).

Need a full week of shifts?

This tool handles one pair of times. To add up Monday through Sunday with unpaid breaks and overtime, use the weekly time card calculator.

Working with more than one calculation?

Upload a CSV of start times, end times and breaks. Batch works out the hours for every row, in hours and decimal hours, instead of one entry at a time.

Batch comes with Pro and Business: up to 5,000 rows a file on Pro, 50,000 on Business.

Frequently asked questions

What time format does it accept?

24-hour HH:MM (e.g. 09:30, 17:45). Most browsers' time inputs handle local formatting automatically.

What if my shift crosses midnight?

Turn on “End time is next day”, or set explicit start and end dates.

How do breaks work?

Enter the break length in hours and minutes. It's subtracted from the total. Breaks longer than the total duration aren't allowed.

Can I use this for timesheets?

Yes, the decimal-hours output is convenient for invoicing or payroll calculations.

Does it handle daylight saving time?

When you provide explicit start and end dates the calculation runs in UTC, so it returns the exact wall-clock difference you entered without DST adjustments.
