How much leave you are really due.
Part-time, joining or leaving mid-year, parental leave, severe disability. The calculator works in twelfths under the Federal Leave Act, shows the day-exact comparison figure beside it and says which figure applies and why.

What is calculated
The rules are set by the Federal Leave Act and other provisions. The calculator applies them.
When someone joins or leaves during the year, the Federal Leave Act often works in twelfths rather than to the day. That means one twelfth for each full month of employment, with part months dropped. Anyone who joins by 30 June and stays keeps the full statutory leave. The same applies to someone who leaves in the second half of the year after the waiting period (§§ 4 and 5 BUrlG). Day-exact calculation is only allowed if the contract expressly says so and nobody falls below the statutory minimum leave as a result (§ 13 para. 1 BUrlG).

24 Mon-Sat days a year on a 6-day week. With fewer working days, pro rata: 24 × working days per week ÷ 6.
Fewer hours per day do not reduce your leave, only fewer working days per week do. If the work pattern changes during the year, each work phase counts by its own working days.
Leave lapses at the end of the year. Until 31 March of the following year it is kept only for urgent operational or personal reasons. It can only lapse, though, if the employer pointed out the remaining leave and the looming lapse in good time (BAG, 19 Feb 2019, 9 AZR 423/16).
