How this is worked out
The notice period in weeks is converted to calendar days and added to the start date, so four weeks means 28 days later.
Worked example
- Notice starts 1 September 2026
- 4 weeks notice
1 September plus 28 days
29 September 2026
Assumptions and limits
- Counts calendar days, so weekends and bank holidays are included.
- Uses the notice length you enter. Statutory minimum notice depends on length of service, and your contract may require more.
- Contracts differ on when notice starts, for example the day after it is given. This is general information, not legal advice.
