As of March 1, 2018 the maximum certificate lifetime will be reduced to 825 days (roughly 27 months/2 years) from the current 39-month limit.
As per CA/Browser Forum Ballot 193 :
Ballot 193 – 825-day Certificate Lifetimes (REVISED v2 – March 2, 2017)
Purpose of Ballot: Recent Ballot 185 demonstrated a consensus among Forum members to reduce the maximum lifetime for DV and OV certificates from 39 months to 825 days (roughly 27 months). This ballot reflects that consensus, and also reduces the maximum period for reuse of vetting data for DV and OV certificates from 39 months to 27 months.
What you need to know
As a result of this industry change, we will remove the ability to create three-year certificates in December 2017 , as any certificate with a lifetime exceeding 825 days after March 1, 2018 will become non-compliant.
