FAQ

Frequently Asked Questions

Everything you need to know about calculating work hours, pause regulations, and industrial decimals.

Decimal hours convert minutes into a fraction of 60. The formula is: Decimal Hours = Hours + (Minutes ÷ 60). For example, 8 hours and 15 minutes is 8 + (15 ÷ 60) = 8.25 decimal hours.

Under standard labor regulations, working between 6 and 9 hours requires at least a 30-minute break. Working more than 9 hours requires at least a 45-minute total break.

Yes! If the end time is earlier than the start time (for example 22:00 to 06:00), the calculator automatically recognizes a cross-midnight shift and calculates the exact duration correctly.

Overtime is calculated by subtracting your daily target hours (e.g. 8.0 hours) from your total net working hours.
