How dates are computed: from the law's enactment date on NYC Legistar plus the effective-date and deadline clauses in the enacted text. Months are converted at 30 days and years at 365 days, so a computed date can differ from an agency's own reading by a few days.

Past due means the deadline passed, not that the agency failed. This tracker reads what laws require; it does not yet check whether each deliverable was produced. A past-due report may well exist; the entry tells you to go ask for it.

Recurring duties list the obligations with annual, quarterly, monthly, or ongoing recurrence. Their first due date appears when the law states one.
