Notice-period deadline
Example: with a 30-day notice and an end date of 31 December, you must submit your notice by 1 December.
How to use
- Enter the contract start date and end date in the fields above.
- Keep the working-days option on if your contract counts Monday to Friday only.
- Read the duration breakdown, totals and months remaining from today.
- Enter your notice days and press Calculate Deadline to see your last day to serve notice.
Tips
- The end date is counted as part of the duration, since the contract is still active on that day.
- Months remaining counts full calendar months from today to the end date, with leftover days shown separately.
- Always check your contract wording: some notice periods are counted in working days, not calendar days.
- This calculator gives estimates for planning only and is not legal advice; confirm dates with your employer or lawyer.
