Notice Period Countdown
Enter your start date and notice period to find your last working day.
Usually the day you handed in your resignation.
The start date counts as day 1, so a four week notice period from a Monday ends on the Sunday four weeks later.
Weekends are always skipped. Choose a set of holidays to skip those too.

This tool calculates your last working day based on when your notice period started and how long it is.
Notice periods can be confusing to calculate, especially in months. Is it the same day of the following month? Does the last day count? This tool does the arithmetic and gives you a clear final date, plus how many calendar and working days remain from today.
How we work it out
For day and week notices, we count forward from your start date by the exact number of days. For month notices, we go forward by the number of calendar months and subtract one day, so a one-month notice starting on the 1st ends on the last day of that month, and when the later month is shorter we use its last day first. For a notice counted in working days, we find the date of the Nth working day, skipping weekends and any holidays you choose. Working days remaining skips weekends and the holidays you chose.
How it's worked out
- For days and weeks, it counts forward from your start date by that many days. The start date counts as day one.
- For months, it goes forward by that many calendar months and takes off one day. If the later month is shorter, it uses that month's last day.
- For working days, it finds the date of the Nth working day, skipping weekends and any holidays you choose.
Starting on 1 September, 4 weeks ends on 28 September, and 1 month ends on 30 September.
Where common notice periods end
| Notice period | Ends on |
|---|---|
| 1 week | Monday 7 September 2026 |
| 2 weeks | Monday 14 September 2026 |
| 4 weeks | Monday 28 September 2026 |
| 1 month | Wednesday 30 September 2026 |
| 2 months | Saturday 31 October 2026 |
| 3 months | Monday 30 November 2026 |
If it starts on Tuesday 1 September 2026, counting the first day as day one. A month ends on the day before the same date next month, or on the last day of a shorter month.
Common mistakes
- Resigning before you have your new job in writing.
- Not reading your contract. Your notice period is whatever it says.
- Counting from the wrong day. Check whether it starts the day you hand it in or the day after.
- Forgetting a handover. Plan what you need to finish before your last day.
Questions
Does the start date count as day one?
Yes. The notice period begins on the date entered, and the final day is the last day of the notice period. The result also shows the date if your contract counts from the day after notice is given.
Are bank holidays counted as working days?
The working days left count skips weekends, and also UK bank holidays or US federal holidays if you choose them above. For a notice counted in days, weeks or months, the last day follows the calendar and is not moved by holidays. For a notice counted in working days, the holidays you choose are skipped.
What if my notice is in working days?
Choose working days and enter the number. The last day is the Nth working day, counting your start date as day one if it is a working day.
What if my employer wants to negotiate a shorter notice?
That is between you and them. This tool just shows what the contract says. Anything negotiated on top of that is a separate conversation.
Is one month the same as four weeks?
No. Four weeks is exactly 28 days. A month runs to the day before the same date next month, which is 28 to 31 days, so the two can end on different dates.
What if my last day falls on a weekend?
The tool shows the exact calendar date. If that date is a Saturday or Sunday, check with your employer whether your last working day is the Friday before or the Monday after.
Does my notice start the day I hand it in?
That depends on your contract. The tool counts from the start date you enter, so put in the date your contract says the notice begins.
