Frequently Asked Questions
What happens if the end time is earlier than the start time?
The calculator assumes the end time falls on the next day and calculates accordingly (useful for overnight shifts).
Can I use 24-hour time?
Yes — the time picker accepts whichever format your device/browser displays by default.
Does this account for time zones?
No — both times are treated as being in the same time zone.
