Time Calculator – Hours & Minutes Between Times
Calculate elapsed hours and minutes between two clock times, including overnight spans.
Quick answer
Elapsed minutes = end − start; if the end is earlier and overnight is enabled, add 24 hours.
9:00 AM to 5:30 PM is 8 hours 30 minutes. 10:00 PM to 6:00 AM is 8 hours when overnight is enabled.
Enter values and calculate.
