How long are TLS/SSL certificate validity periods?

TLS/SSL certificate validity periods are currently 398 days, or about 13 months. They were recently reduced by the CA/B Forum starting Sept. 1, 2020 in response to Apple’s announcement stating they would not accept certificates for two-year validity periods. DigiCert has instituted a 397-day validity period in order to account for time zone differences.
