As of April 1st, 2015, the lifetime of SSL certificates has now been reduced to 39 months, in accordance with the CA/Browser Forum Baseline Requirements. Moving forward, consider using shorter life certificates. Even though the maximum validity period is now 39 months, you can drop this validity period to one or two years. Consider the validity period as the backstop to protecting your private key, your website, and your user’s data. But remember one important item, when you renew your certificate, please create a new private key.

The CA/Browser Forum has taken a progressive step by reducing SSL/TLS certificate lifetimes from 39 months (~1185 days) to 27 months (stated as 825 days for computational ease). The move to an 825-day maximum certificate validity period for all types of certificates (DV, OV, and EV) will be effective for all new certificates purchased on or after of March 1, 2018. Why Change the Certificate Lifetime? The goal of reducing the lifetime is it allows certificates to be changed more frequently.
