Frequently Asked Questions

How does the calculator handle overnight shifts?
If the end time is earlier than the start time (e.g. starting at 9:00 PM and ending at 5:00 AM), the calculator automatically assumes that the end time belongs to the next calendar day, and calculates the duration correctly as 8 hours.
Can I input minutes as well?
Yes! The subpage slot format supports minutes (e.g., `930am-5pm` or `815am-430pm`), and the custom time picker supports standard minute increments directly.
Is my time tracking data uploaded anywhere?
No, your privacy is 100% assured. The calculations are processed entirely locally on your device within your web browser sandbox.
