Contract Renewal Calculator

Enter the contract end date and the renewal or cancellation notice period your agreement requires. The calculator works backward from the end date using the same calendar-day, business-day, and month rules as the Notice Period Calculator—just in reverse, like the Resignation Notice Calculator.

Many contracts auto-renew unless you give notice a set number of days, weeks, or months before the end date. This calculator finds that exact deadline so you don't miss it.

Calendar mode counts every UTC calendar day backward from the end date. Business-day mode skips weekends and can optionally skip a sample US federal holiday list, matching the Add/Subtract Business Days calculators.

Avoiding unwanted auto-renewal, planning vendor or lease contract cancellation, and confirming a renewal notice deadline stated in an agreement.

The Business Days Until Date Calculator counts business days remaining until a target date from today or a custom start date, with calendar days remaining and optional US federal holiday exclusion.
