Tenancy ends on
31 January 2027
| Notice period | 3 months |
| 3rd working day this month | 4 November 2026 |
| Does the month of receipt count? | yes |
What counts is when the notice reaches the other side, not when it was sent. Saturday counts as a working day, Sundays and public holidays do not.
How we calculateOrdinary notice on an open-ended German residential lease must reach the other side by the third working day of a month, and the tenancy then ends at the close of the month after next (Section 573c of the Civil Code). For tenants that is always 3 months, however long they have lived there. For landlords the period grows by three months after five and after eight years from handover, to six and nine months. What counts is receipt by the other side. Saturday counts as a working day (Federal Court of Justice, 27 April 2005, VIII ZR 206/04); Sundays and public holidays do not, which is why the calculator asks for your state. A Berlin example: if your notice arrives on 4 November 2026, the third working day, the tenancy ends on 31 January 2027. If it arrives on 5 November, it ends only on 28 February 2027. If the landlord gives notice on a flat handed over in April 2019, six months apply, to 30 April 2027.
How the calculator works
It finds the third working day in the month of receipt: Monday to Saturday count, Sundays and public holidays do not. Besides national holidays it includes the holidays of your state that can fall in the first days of a month, such as 6 January in Bavaria, Baden-Württemberg and Saxony-Anhalt or 1 November in North Rhine-Westphalia. If notice arrives by that day, the current month counts; otherwise the period starts the following month. The end is the last day of the month in which the period runs out. For a landlord it counts the years since the flat was handed over, the move-in, not the signing.
| Case | Period | End |
|---|---|---|
| tenant, received 4 November 2026 | 3 months | 31 January 2027 |
| tenant, received 5 November 2026 | 3 months | 28 February 2027 |
| landlord, flat since April 2019 | 6 months | 30 April 2027 |
| landlord, flat since April 2016 | 9 months | 31 July 2027 |
What the calculator does not check
Whether a landlord may give notice at all is not in Section 573c but in Section 573 BGB: he needs a legitimate interest, such as own use (Eigenbedarf), and must state the reasons in the letter. The own-use eviction page explains conditions, objections and waiting periods. Shorter periods apply to furnished rooms in the landlord's own flat and to temporary lettings; the calculator does not cover these.
