Part-Time Holiday Entitlement under BUrlG §3 – Key Facts
Part-time employees in Germany have the same statutory holiday entitlement as full-time workers – measured in calendar weeks, not days. The decisive factor is the number of working days per week, not hours. This follows from §3 of the Federal Holiday Act (BUrlG), which mandates four weeks of minimum leave for all employees.
The Formula for 3-Day, 4-Day Weeks and More
Part-time holiday entitlement is calculated using the proportionality principle:
Part-time holiday days = Full-time days × (Part-time days per week ÷ Full-time days per week)
Practical examples:
- 3-day week with 30 full-time days: 30 × (3/5) = 18 days
- 4-day week with 30 full-time days: 30 × (4/5) = 24 days
Mid-Year Start: §5 BUrlG
Employees starting after January 1st are entitled to one-twelfth of annual leave per full month of employment under §5 BUrlG. Starting in April means 9/12 of annual leave. Fractions of 0.5 days or more are rounded up; below 0.5 are rounded down (§5(2) BUrlG).
Switching Full-Time to Part-Time Mid-Year
Per BAG ruling (9 AZR 406/17), when switching during the year, each period is calculated separately and the results added together. E.g., switching in July: 6 months full-time + 6 months part-time – each calculated independently.
Does This Apply to Mini-Jobs and Working Students?
Yes. The BUrlG applies to all employees in Germany – regardless of pay level or working hours. Mini-job holders, working students, and marginal employees are also entitled to proportional leave. Collective agreements may provide more favourable terms under §13 BUrlG; the statutory entitlement is the minimum.
Part-Time Holiday Entitlement in Practice: 20- and 30-Hour Contracts
Typical part-time models combine weekly hours and working days. The calculation always follows the same proportionality principle: part-time holiday days = full-time holiday days × (part-time days per week ÷ full-time days per week).
- 20 hours, 3-day week with 30 full-time days (5 days): 30 × (3/5) = 18 days – this matches the query "part-time holiday entitlement 20 hours 3-day week".
- 20 hours, 4-day week with 30 full-time days: 30 × (4/5) = 24 days.
- 30 hours, 5-day week with 30 full-time days: still 30 days, because the number of working days per week is the same.
