Time Duration Calculator – Calculate Hours Between Two Times
This time duration calculator helps you calculate the exact hours between two times instantly. Whether you need to track work hours, calculate overtime, or measure time differences, this tool provides accurate results.
How to Calculate Time Difference
Step 1: Convert Time to Minutes
Total Minutes = (Hours × 60) + Minutes
Step 2: Subtract Start from End
Duration = End Time − Start Time
Step 3: Convert Back to Hours
Total Hours = Total Minutes ÷ 60
Handling Midnight Crossovers
If the end time is earlier than the start time, the calculator assumes the time crosses midnight and adds 24 hours automatically.
Example Calculation
Start: 10:30 PM
End: 2:15 AM
Adjusted End = 2:15 AM + 24 hours
Duration = 3 hours 45 minutes
