How to use this calculator

Enter the current renewal anniversary, term months, notice lead limits and working-day delivery allowance. Choose whether a closed deadline moves to the previous open date.

Both receipt-window endpoints count. Delivery lead subtracts working days from the final receipt date. Each anniversary remains anchored to the original day, clamping short months; an adjustment that closes the whole window is reported.

A worked example

A January 31, 2027 renewal with a 30-day latest notice lead has a January 1 receipt deadline. With no entered closures and three Monday-Friday delivery days, dispatch is December 29, 2026.

Are holidays included automatically?

No. Enter the closures and delivery allowance that apply to the agreement. The calculation is a planning aid, not a determination of valid legal notice or guaranteed delivery.

Which calendar and years are supported?

Use Gregorian dates from 1900 through 2100, with results in that range. Most daily plans allow up to 366 dates; service-budget searches allow 731. Timed intervals have exclusive ends and use browser IANA time-zone rules; nonexistent local times are rejected and repeated times require your choice. Working calendars and policy terms are entered by you. The holiday comparison uses TimeCubby's published country/region coverage. Copy, CSV and print include assumptions; calendar exports appear when dated events exist.
