How the UK notice period calculator works
Enter the date you give notice and choose a period: 1 week, 4 weeks, a month counted as 30 days, 12 weeks, 3 months counted as 90 days, or your own number of days. Notice is counted from the day after you hand it in by default, which is the usual reading in the UK, but you can switch that if your contract counts the day itself.
The result shows your last working day, the calendar days in your notice, how many are weekends, and the working days left. UK bank holidays are not built in, so add the number that falls inside your notice and they come off the working-day count.
Below the main result there is a statutory panel. Enter your full years and extra months of service and it shows the minimum notice your employer must give you under the GOV.UK rules, and the minimum you must give. Your contract can ask for more, and when it does, the longer figure is the one that applies. Nothing you enter leaves your browser.
Example: 4 weeks' notice from Friday 6 November 2026
You resign on Friday 6 November 2026 with four weeks' notice starting the next day. Your last working day is Friday 4 December 2026. That is 28 calendar days with 8 weekend days, so 20 working days.
If your contract says one month instead, the 30-day preset lands on Sunday 6 December, which here matches the calendar month because November has 30 days. With 3 years of service, the statutory panel shows your employer must give you at least 3 weeks, and you must give at least 1 week unless your contract says more.
Tips for better results
- Check whether your contract says weeks or months. A calendar month runs to the same date next month and can be 28 to 31 days.
- Give notice in writing with the date on it, even if your contract allows verbal notice, so nobody argues about when it started.
- Ask early whether you will work your notice or go on garden leave, since it changes when you can start the new job.
- Add any bank holidays inside your notice to the holidays field before you plan your handover days.
