Three dates, three meanings
Contract end is not always the last day at your desk.
A reliable answer separates the legal employment end date from the final day physically worked and the first date another job can begin.
Employment ends
The calendar notice period expires on this date unless a different arrangement is agreed.
New role starts
Normally the following day, subject to garden leave, restrictive terms or another agreement.
Evidence checked
Built from current official guidance.
GOV.UK and Acas confirm that resignation notice usually starts the day after it is received and that employees normally owe at least one week after one month’s service. GOV.UK separately sets the employer minimum at one week per complete year from two years, capped at 12 weeks.
The DWP Decision Makers’ Guide supplies the date-counting examples used here, including Monday-to-Monday for one week and the special end-of-month treatment for calendar months. Contract wording and individual circumstances still take priority.

FAQ
UK notice period questions.
How much notice must I give when resigning in the UK?+
An employee who has worked for at least one month normally must give at least one week’s notice. A contract, written statement or staff policy can require more. If you have worked for less than one month and no written term applies, Acas says there is no statutory minimum.
When does a notice period start?+
Unless the employment contract says otherwise, GOV.UK and Acas say it usually starts the day after notice is received. A one-week notice handed in on Monday therefore runs out the following Monday.
Does one month mean four weeks?+
No. This calculator treats a month as a calendar month, not 28 days. Official DWP guidance gives an example where notice on 14 June expires on 14 July and applies a special month-end rule: notice on 29 February expires on 31 March.
Do weekends and bank holidays count? +
Notice stated in calendar days, weeks or months continues across weekends and bank holidays. If the contractual end date falls on a day you do not normally work, your final day physically worked may be earlier. Check contracts that use a specific working-day rule.
Is statutory notice one week per year?+
That rule applies to notice an employer gives an employee for dismissal or redundancy: one week after one month, then one week per complete year from two years, capped at 12 weeks. The employee’s statutory minimum when resigning stays at one week after one month, although a contract may require more.
Can I leave before my calculated end date?+
You can ask your employer to agree an earlier release and should get that agreement in writing. Acas warns that leaving early without agreement may breach the contract. Garden leave or payment in lieu of notice can also affect when you stop working or when employment ends.
