Notice Period Deadline Calculator
Contracts, leases and supplier agreements often say that something must happen a set number of days after a notice is sent. This calculator answers one question: on what date does that notice period end? Enter the send date and the number of notice days, and it returns the deadline. It is a date aid for orientation, not legal advice on when notice is legally effective.

What this law tool gives you
The output shows the deadline as a full date, alongside the send date and the number of days you entered, with the formula underneath. Put it straight into a calendar invite or a handover note so everyone works from the same date instead of counting on their fingers.
What you enter
- Send date: the date the notice is sent (calendar date)
- Notice days: the notice period as a whole number of calendar days
Worked example
With the tool's example, a notice sent on March 2, 2026 with a 14-day notice period has a deadline of March 16, 2026. The page shows Deadline: March 16, 2026, Send date: March 2, 2026 and Notice days: 14, followed by the formula deadline = send date + notice days, as calendar days.
How is a notice deadline calculated?
Deadline = send date + notice days. The days are calendar days, not business days, so weekends and public holidays are counted like any other day. The notice period must be a whole number of zero or more.
The tool does not move the deadline off a weekend or holiday, and it does not decide whether the day of sending counts as day zero or day one. It simply adds the number of days to the send date, so day one is the day after sending.
Tips before you use the result
- Check whether your contract counts business days. If it does, this calendar-day result will be too early.
- Contracts often say notice is effective when received, not when sent. Use the receipt date as the start if that is the rule.
- If the deadline lands on a weekend or holiday, read the contract for what happens next; the tool will not adjust the date.
- Keep proof of the send date, such as a courier receipt or email timestamp, with the calculated deadline.
Frequently asked questions
Does a 30-day notice period include weekends?
In this calculator, yes. It counts calendar days, so Saturdays, Sundays and holidays are included. Many contracts use calendar days, but some specify business or working days. Read the notice clause before relying on the result, and adjust the day count if your agreement excludes weekends or public holidays.
Is the day the notice is sent counted?
The tool adds the notice days to the send date, so the day of sending is not counted and the next day is day one. A 14-day notice sent on March 2 ends on March 16. Some contracts or local rules count differently, so check the wording if the exact day matters.
Can I rely on this date legally?
Treat it as a calculation aid. It adds days to a date and nothing more; it does not know your contract, how notice must be served, or local law. It is not legal advice. For a deadline with real consequences, confirm the counting rule with the contract owner or your lawyer.
Will the calculator remember my dates?
Yes, on this device. The send date and notice days are saved in your browser as you type, without an account, and are still there when you come back. Press Clear to start a new notice, or Copy output to paste the result into a message.
