How to maintain compliance calendar?

Maintaining a compliance calendar comes down to three habits: capture immediately, review on schedule, and assign every date an owner.

Capture: the moment any obligation enters the business (new license, signed contract, new policy, hired role with training requirements), its dates go into the calendar the same day, with expiry/due date, renewal lead time and the documents attached. 'I'll add it later' is how calendars rot.

Review: a short monthly pass over the next 90 days of deadlines (are owners aware? anything blocked?) and a deeper quarterly audit checking for obligations that never got captured.

Ownership: every item names one person, not a team, who gets the reminders and answers for the outcome. When someone leaves, their items get reassigned as part of offboarding, which is exactly when tracked-in-one-place beats tracked-in-their-head.
