Frequently Asked Questions
How does the calculator handle overnight time?
If the end time is earlier than the start time, it treats the interval as crossing midnight.
Are breaks subtracted?
Yes when you enter a break duration.
What does rounding do?
Rounding moves the result to the nearest selected interval, such as 15 minutes.
Can this be used for payroll?
It can help estimate hours, but payroll should follow employer policy and applicable labor rules.
Why is decimal time different from hours and minutes?
Decimal time expresses minutes as a fraction of an hour, such as 7.5 hours for 7 hours 30 minutes.
