Renewal Deadline Planner

Use this when you know a renewal date and calendar-day notice period and want planning dates or a calendar file. One supplied renewal date per call; notice periods are 0–3,660 calendar days and preparation lead is 0–365 days. Calendar export requires a stable unique planId for each contract and renewal cycle. Reuse that ID for an update and use a new ID for another contract or cycle. No business-day adjustment, cancellation or installed reminder. Inputs are temporary; no customer-account access or stored progress. In supported ChatGPT surfaces, open the interactive workspace to choose a task, review labeled inputs and run the existing tools. Examples are public or synthetic, not saved customer records. The public website provides a labeled example, usage steps and prompts. The interface adds no account access or persistence.
