Notice period end date calculator
Enter the date notice is given, the notice length and how you want the days counted. The result is an estimate, not a legal decision.
How the notice period end date calculator works
The calculator starts from the date notice is given, then counts the notice length using either calendar days or working days. Calendar days include weekends. Working days exclude weekends and, if selected, UK bank holidays for the chosen region.
Acas explains that notice periods depend on the circumstances and the contract or written statement. Use this calculator as a planning estimate, not as employment-law advice.
Calendar days vs working days
A calendar-day notice period counts every day on the calendar. A working-day notice period usually excludes weekends and may exclude bank holidays, depending on the contract or policy.
| Counting method | What it usually means |
|---|---|
| Calendar days | Every day is counted, including Saturdays and Sundays. |
| Weeks | Usually a calendar period unless the wording says working weeks or working days. |
| Working days | Weekends are excluded; selected UK bank holidays can also be excluded. |
UK bank holiday handling
The working-day option can exclude bank holidays for England and Wales, Scotland or Northern Ireland. GOV.UK publishes separate calendars because bank holidays differ by UK nation.
Where a bank holiday falls on a weekend, GOV.UK says a substitute weekday normally becomes the bank holiday. This matters for Christmas and Boxing Day calculations in some years.
Notice date formula
if counting from next day:
start date = notice given date + 1 day
else:
start date = notice given date
if calendar days:
provisional end = add notice length in days, weeks or months
if working days:
count valid working days until the required notice length is reached
if final-day adjustment selected:
move result to the previous or next working dayNotice period examples

Notice period end date FAQs
Does a notice period include weekends?
It depends on the wording. Calendar days and weeks usually include weekends, while working-day notice excludes weekends. Your contract or employer policy should be the source of truth.
Do bank holidays count in a notice period?
They usually matter when the notice period is counted in working days, or when the final working day is adjusted. Bank holidays can differ between England and Wales, Scotland and Northern Ireland.
Can this calculator decide my legal notice period?
No. It estimates the end date from the notice length you enter. Acas guidance and your contract or written statement matter if there is a dispute or uncertainty.
