Planned: weekly instead of daily maximum hours, not yet in force
The governing coalition wants to replace the daily maximum working time with a weekly one. A draft bill from the Labour Ministry has existed since June 2026; under it, the weekly limit would only apply with a collective agreement or a works agreement based on one. There is no cabinet decision yet (as of September 2026). The calculator therefore checks against the current Working Hours Act: 8 hours a day, 10 at most.

All within limits: breaks, maximum daily hours and rest periods comply with the German Working Hours Act.
The check only sees the week you entered. It cannot verify whether you take a break after 6 hours in a row, how the break is split (blocks of at least 15 minutes) or whether collective agreements allow deviations.

Decimal time ("industrial minutes") divides the hour into 100 instead of 60 parts. The formula: minutes ÷ 60. So 15 minutes become 0.25 hours.
