Count only completed months: since joining in the first year, or within the preceding year for below-80% attendance.

Under 15 hours/week is excluded from this statutory leave model. Part-time entitlement is also expressed proportionately in hours.

Amounts, employment dates and deductions are calculated only in this browser tab, without sending or saving them to a server, URL or persistent storage. Result files you choose to save remain on your device.

How to use this tool

  1. Set the employment start and a reference date on which employment continues.
  2. Set attendance and completed fully attended months, then enter hours used.
  3. Distinguish full-time-equivalent days from granted and remaining hours at your work schedule.

Uses employment anniversaries in a workplace with at least five regular employees and continuing employment.

Why the calculation covers one grant

In the first year, enter completed fully attended months, up to 11. After one year with continuing employment and at least 80% attendance, the model grants 15 days, adding one per two service years from year three and capping the grant at 25.

First-year monthly leave is not accumulated together with later annual grants into a lifetime balance. Expiration, carry-over, leave-use procedures and retirement settlement require separate company and individual eligibility checks.

Compare part-time entitlement in hours

The base eligibility conditions are a workplace with at least five regular employees and at least 15 scheduled hours/week. Part-time entitlement is proportional to a 40-hour comparator, with a remaining fraction rounded up to one full hour.

Enter usage in hours as well, avoiding assumptions about days worked per week or hours per working day. A zero balance does not determine whether additional contractual or carried-over leave exists.

Common questions

Does exactly one year of work followed by departure always create 15 days?

The reference date assumes continuing employment after completing the year. Do not apply that assumption unchanged to an expired contract or retirement case.
