Frequently Asked Questions
How do you calculate hours worked between start and end times?
Subtract start time from end time. If the shift spans past midnight, add 24 hours to the end time before subtracting.
How do break deductions work in work hour calculations?
Total Work Hours = (End Time − Start Time) − Unpaid Break Duration.
How do you convert decimal hours to minutes?
Multiply the decimal portion by 60 (e.g. 7.5 hours = 7 hours and 0.5 × 60 = 30 minutes).
Can I calculate military 24-hour time shifts?
Yes. Input start and end times in standard 12-hour (AM/PM) or 24-hour format.
