• Deadline preparation:Work backward from a submission or filing date to find the last safe preparation day.
• Cancellation windows:Calculate the final date to cancel or amend an order before a fixed cutoff.
• Audit backtracking:Trace an earlier date when checking records, logs, or compliance evidence.
