Frequently Asked Questions

Q: Can it calculate night shift hours?

Yes. If the end time is less than the start time (e.g., 22:00 to 06:00), it automatically detects overnight crossover and calculates correctly.

Q: What's the range for date difference?

You can calculate between any two dates, from days to years apart. Results show in days, weeks, months, and years.

Q: Does the result include both start and end?

The duration is the elapsed time from start to end. For example, 09:00 to 17:00 is exactly 8 hours.

Q: Can I use this on my phone?

Yes. The tool is responsive and works on phones, tablets, and desktops.

Q: How do I calculate work hours?

Use Time Difference mode. Enter your start and end times. If you have a lunch break, subtract it manually. E.g., 09:00 to 18:00 minus 1 hour break = 8 hours.
