Back-count of full notice days before renewal
- 01
Count N full notice days backwards from the day before renewal - 02
Deadline = the day before that window (moved earlier past weekends for business-day notice)
Limits — read before relying on it
- Conservative reading: notice must be received with N full days before the renewal date. Some contracts count differently — check yours.
- Public holidays are not excluded for business-day notice.
- Time zones and cut-off times (e.g. 'by 11:59 pm PT') are not modeled.
