End date = start date + notice period + buffer - exclusions
The selected mode determines whether the calculator adds calendar days, working days, weeks, or calendar months.
- Different contracts define notice by calendar days, working days, weeks, or months.
- Weekend and holiday exclusions are only counted where the selected mode requires them.
- Notice periods can be defined by contract, employment policy, statute, or local rules. This calculator models dates but does not decide legal compliance.

Insights for this scenario
Contracts control the rule
Always compare the result with the notice wording in your employment, lease, or service contract.
Working days differ by region
Public holidays and weekend customs vary, so add your own holiday dates for a closer estimate.
Reverse mode helps planning
Use reverse calculation when you know the final day and need the latest notice start date.

FAQ
Notice Period Calculator FAQs
How does the notice period calculator work?+
It uses End offset = notice days + excluded days + buffer and calculates the result from the values you enter.
Can I copy or print the result?+
Yes. AZCalculate calculator pages include copy, share, and print actions.
What is a notice period?+
A notice period is the time between giving notice and the expected end date of employment, tenancy, service, or another agreement.
What is the difference between calendar days and working days?+
Calendar days count every date, while working days usually exclude weekends and any holidays entered by the user.
Does the first day count in the notice period?+
It depends on the contract or local rule. This calculator lets you choose whether to include the start date.
How are weekends handled?+
Weekend days are counted separately and excluded from working-day calculations where applicable.
Can I add public holidays?+
Yes. Enter holiday dates as comma or space separated YYYY-MM-DD values so they are excluded from working-day counts.
Does month-end or leap year handling work?+
Calendar-month mode preserves the intended day as closely as possible, including February and month-end dates.
Can I calculate the latest date to give notice?+
Yes. Reverse mode uses a target end date and works backward to estimate the required start date.
Is this legal advice?+
No. Notice periods can depend on contracts, statutes, policy, and location. Verify the result with a qualified professional or official source.
