When to use this calculator

Use this calculator when you know the notice start date and period length and need to find the end date. It handles employment resignations, contract terminations, rental notices, vendor agreements, and any situation where a fixed length runs forward from a start date.

  • Employment resignation

    Find when a two-week or one-month notice period ends from the date you hand in your letter.

  • Rental notice

    Estimate a move-out date from a lease-stated notice length in days or months.

  • Contract termination

    Pair with the Contract End Date Calculator when notice must be served before a contract expiry date.

  • Vendor or service agreement

    Plan the last day of a cancellation or non-renewal window.

  • Handoff planning

    Use the 14- and 30-day reminders to schedule tasks before the notice period closes.

Inputs

  • Notice start date

    The date notice was formally given or received. Check your contract or policy for whether the clock starts on the date of delivery or the following day.

  • Notice period length

    The numeric value from your contract or policy: for example, 14, 2, or 1.

  • Unit (days, weeks, or months)

    The time unit that matches your contract. Days and weeks add a fixed number of days; months use calendar-month math with end-of-month clamping.

  • Calendar or business days

    Calendar days count every day of the week. Business days skip Saturday and Sunday—and optionally US federal holidays when that option is enabled.

  • Exclude US federal holidays

    In business-day mode, enabling this skips a standard list of US federal holidays from the count. Only relevant if your policy treats holidays as non-working days.

  • Include start date

    When on, the notice start date is counted as day one. When off, the period starts the following day. Many employment contracts use 'off'; check your wording.

How the calculation works

The calculator adds the notice length forward from the start date. For days, it counts forward the exact number of calendar or business days. For weeks in calendar mode, it multiplies by seven; in business-day mode, it counts five business days per week. For months, it adds the number of calendar months directly to the start date and clamps to the last day of the resulting month when the start day falls beyond month-end (for example, 31 January plus one month becomes 28 February in non-leap years).

In business-day mode, Saturday and Sunday are not counted toward the notice length. When the holiday exclusion is on, the listed US federal holidays are also skipped—the notice period takes longer in calendar time as a result.

The include-start-date setting controls whether the start date counts as day one of the notice period. With it off, the first counted day is the day after the start date, making the end date one day later.

Reminder dates are simple calendar subtractions from the end date—7, 14, and 30 days back—intended for scheduling tasks before the period closes. They are not adjusted for weekends or holidays.

Worked example

Notice start date: Monday 3 March 2025. Notice period: 4 weeks, calendar days, start date not counted.

The calculator adds 28 calendar days from 3 March (not counting 3 March itself). Result: Monday 31 March 2025.

Planning reminders: 24 March (7 days before), 17 March (14 days before), 1 March (30 days before).

If the same notice were given in business-day mode with start not counted, 4 weeks × 5 business days = 20 business days forward from 3 March, landing on Monday 31 March 2025 as well—but this result would differ if weekends fell differently across the period or if holidays were excluded.

Edge cases

  • End date on a weekend

    Calendar-day notice can produce a Saturday or Sunday end date. The calculator does not automatically adjust this. Use the Last Working Day Calculator to shift the result to the nearest working day.

  • Month-end start dates

    Giving notice on 31 January with a one-month period produces 28 February in a non-leap year (end-of-month clamping). Two months from 31 January gives 31 March. Verify month-add results when your start date is at the end of a long month.

  • Include start date is on

    When the start date is counted as day one, a two-week calendar period ending on 3 March would end on 16 March with start-not-included but on 15 March with start-included—one day earlier.

  • Weeks in business-day mode

    Two weeks in business-day mode counts as 10 business days, not 14 calendar days. The calendar end date will be later than two calendar weeks from the start.

  • Holidays only count in business-day mode

    In calendar-day mode, holidays are counted like any other day. Skipping US federal holidays only applies in business-day mode when the holiday exclusion option is enabled.

FAQ

How do I calculate a notice period end date?
Enter the notice start date, the period length, and the unit (days, weeks, or months). Choose calendar or business days and whether the start date counts as day one. The calculator shows the end date plus optional reminder dates.
Are notice periods counted in calendar days or business days?
It depends on your contract, policy, or statute. This calculator supports both: calendar days count every day; business days skip weekends and can exclude a sample US federal holiday list. Always verify which rule applies to your situation.
Should the start date be included?
Documents differ. When 'include start date' is off, the length is added forward without counting the start day. When on, the start day is day one. Check your notice clause before relying on the result.
What are the reminder dates for?
The 7-, 14-, and 30-day reminders are planning dates—useful for scheduling tasks such as returning equipment, completing handovers, or sending follow-up communications before the notice period ends. They are calculated by subtracting calendar days from the end date.
What if my notice period is stated in months?
Select months as the unit. The calculator adds the count directly to the month component of the start date, clamping to the last day of the target month when needed. One month from 31 January gives 28 February in non-leap years; two months gives 31 March.
Is this legal or employment advice?
No. Notice rules vary by jurisdiction, contract, and policy. Use these dates for planning and confirm with your agreement, employer, landlord, or qualified advisor.
