Frequently Asked Questions
How does the 'Next day' toggle work?
If your shift starts in the evening and ends the next morning (e.g. 10 PM - 6 AM), enable this toggle to correctly calculate the difference across midnight.

The monthly projection uses 22 working days as a standard average. The annual projection uses 261 working days (52 weeks × 5 days). These are standard estimates.
