Frequently Asked Questions
What if the end time is past midnight?
Check the "End time is next day" box. This adds 24 hours to the end time, allowing you to calculate durations that span midnight, such as overnight shifts (e.g., 10:00 PM to 6:00 AM).
How do I calculate total work hours for a week?
Calculate each day's hours separately using this tool and add them together. Alternatively, multiply daily hours by work days if your schedule is consistent.
