#### Formula

Expiry Date = Issue Date + Validity Years + Validity Months

Hard Deadline = Expiry Date + Grace Period (days)

Early Renewal Window Opens = Expiry Date − Early Renewal Window (days)

Days to Expiry = Expiry Date − Today (in days)

Days to Hard Deadline = Hard Deadline − Today (in days)
