Looking for a hours between two times calculator? This free tool gives you exact hours and minutes between start and end times, overnight too. Just enter your numbers and press Calculate — results are instant.
Hours between two times is simple subtraction once both times are in minutes: convert each HH:MM time to minutes after midnight and take the difference. If the end time is earlier than the start time, the calculator adds 24 hours and counts it as overnight. Times use the 24-hour clock, so 5:30 PM is written as 17:30.
Example: Start time 09:00 · End time 17:30
Duration: 8 hours, 30 minutes
Enter the end time as usual — if it is earlier than the start time, the calculator adds 24 hours and marks it as overnight. So 22:00 to 06:00 is 8 hours.
No. Enter the start and end of the working period itself, or work out the break separately and subtract it from the result.
It removes the AM/PM confusion: 17:30 can only mean half past five in the afternoon. Convert PM times by adding 12 to the hour.
