Frequently Asked Questions
1. Can I use this to add or subtract time manually?
Yes. You can enter a start and end time to add or subtract the difference. For manual time math, just set one value as the base and the other as the time you want to offset.
2. Does it work with 24-hour time format?
Absolutely. The calculator supports both 12-hour (AM/PM) and 24-hour formats. Just ensure you input times consistently.
3. Can it calculate across multiple hours?
Yes. If your start and end times span multiple hours, the calculator will return the result in hours, minutes, seconds, making it ideal for long-duration calculations.
