Frequently Asked Questions

How do I add time durations?

Add seconds, minutes, and hours separately. If seconds > 59, subtract 60 and add 1 minute. Do the same for minutes. Our calculator handles this carry-over automatically.

How do I subtract time and handle negative results?

Enter your start and end times and select Subtract mode. If the result would be negative (e.g., 1:00 minus 1:30), the calculator shows the absolute difference and flags the direction. Useful for calculating elapsed time and overtime.

Can I convert hours and minutes to a decimal?

Yes. For example, 1 hour 30 minutes = 1.5 hours (divide minutes by 60 and add to hours). Decimal mode in this calculator converts any H:MM:SS input to its decimal equivalent, which is useful for payroll and billing calculations.
