Notice deadline calculator
Find the last day to give notice before a contract renews. Enter the date your notice clause counts back from and the notice period, and the deadline appears below.
How to read a notice clause
A typical automatic renewal clause reads something like this:
“This Agreement shall automatically renew for successive one-year terms unless either party gives written notice of non-renewal at least sixty (60) days before the end of the then-current term.”
Three things go into the calculator: the date the clause counts back from (here, the end of the current term), the number (60) and the unit (days). If the clause says “business days”, switch the count to business days. The answer is the last day notice can be given. Read the rest of the clause too: it usually says how notice must be delivered, and whether it counts when sent or when received.
Year-end renewals: the dates for 2026
Many business contracts run on the calendar year. If yours renews at the start of 2027, the deadline depends on whether the clause counts back from the last day of the term or from the renewal date:
| Notice | Before the term ends Dec 31, 2026 | Before a Jan 1, 2027 renewal |
|---|---|---|
| 30 days | Tuesday, December 1, 2026 | Wednesday, December 2, 2026 |
| 60 days | Sunday, November 1, 2026 | Monday, November 2, 2026 |
| 90 days | Friday, October 2, 2026 | Saturday, October 3, 2026 |
Calendar days, with no adjustment for weekends. November 1, 2026 is a Sunday, so for 60 days before December 31 the safe plan is for notice to arrive by Friday, October 30.

Worked examples
Each one counts back from the date in the clause, the same way the calculator and the Keepwatch app do.
- 60 calendar days before December 31, 2026: Sunday, November 1, 2026. Plan for notice to arrive by Friday, October 30.
- 30 business days before December 31, 2026: Tuesday, November 17, 2026. Thanksgiving and Christmas don’t count as business days.
- 45 business days before January 15, 2027: Monday, November 9, 2026. Counting only weekends gives Friday, November 13, four days too late: Veterans Day, Thanksgiving, Christmas and New Year’s Day all fall inside the window.
- 3 months before May 31, 2027: Sunday, February 28, 2027. February has no 31st, so the date moves to the last day of the month.
- 90 calendar days before June 30, 2027: Thursday, April 1, 2027.
Try any of them: 45 business days before January 15, 2027.
Calendar days, business days and months
Calendar days count every day, weekends and holidays included. Business days skip Saturdays, Sundays and holidays, so 30 business days reaches back about six weeks. Months are counted on the calendar: two months before April 30 is February 28, not a date 60 days earlier.
Common questions
What is a notice deadline?
It is the last day you can tell the other side you will not renew, or that you are ending the contract. Most automatically renewing contracts require notice a set number of days or months before the term ends, so the notice deadline usually comes well before the expiration date. Miss it and the contract typically renews for another term.
Does the deadline move if it falls on a weekend or a holiday?
Don't assume it does. Unless your contract says a deadline that falls on a weekend or holiday moves to the next business day, plan for your notice to arrive by the last business day before it. The calculator shows that earlier date when it applies.
Is the deadline the day I send notice or the day it is received?
It depends on the notice clause. Many contracts say notice is effective when it is received, or a set number of days after it is mailed. Read the delivery part of the clause and allow time for the method it requires, such as certified mail or overnight courier.
How does the calculator count business days?
It skips Saturdays, Sundays and the eleven U.S. federal holidays, using the dates they are observed: a holiday that falls on a Saturday is observed the Friday before, and one that falls on a Sunday the Monday after. If your contract defines business days differently, for example by excluding a state or bank holiday, check the result against your contract.
How are months counted?
As calendar months, not as 30-day blocks. Three months before May 31 is February 28 (or February 29 in a leap year), because February has no 31st. That is how most contracts and billing systems treat month-end dates.
Should I use the expiration date or the renewal date?
Use the date your notice clause counts back from. “Sixty days before the end of the term” counts back from the last day of the term, such as December 31. “Sixty days before the renewal date” may count back from January 1. That one-day difference moves the deadline by a day.
Is this legal advice?
No. The calculator does date arithmetic on the terms you enter. Your contract controls, and its wording can change the answer. For advice about a specific agreement, consult an attorney.
