Hours worked

(per week)

How can I calculate my working hours?

You can calculate the working hours of any week by using Breathe's working hours calculator above. Just type in each working shift or use the dropdown box provided.


What are my maximum working hours?

Maximum working hours are capped at 48 hours a week, on average, under the working time directive. (This applies to adults over 18.) 

If you opt out of this law, you can choose to work more hours than this.


Calculating working time hours for part-time employees

There isn’t an official number of weekly hours that makes someone a part-time worker, but a full-time worker will normally work around 35 hours per week.   


Calculating rest breaks

Legally, workers are entitled to one uninterrupted 20-minute rest break if they work more than 6 hours per day (regardless of if they work full or part-time).  

This doesn’t have to be paid – it depends on their employment contract whether it is or not.
