How to use the Notice Period Calculator
Select a notice start date, enter the notice length and choose calendar or working-day behavior where available. The tool returns an estimated final date.
Formula / calculation logic
The selected notice period is added to the start date according to the chosen unit and inclusion rule; working-day mode skips weekends.
Worked example
A 30-calendar-day period starting 21 August 2026 reaches 20 September 2026 when the starting day is not counted as day one.
Important notes
Employment contracts and laws can define notice periods differently, including holidays and start-day rules. This is date arithmetic, not legal advice.
Frequently asked questions
Are public holidays excluded?
No. Working-day mode skips weekends only.
