The eligibility window was extended beyond 12 months once before — in advance of the sixth Academy Awards in 1934.
The 74th Tony Awards, originally set for 7 June, have been postponed indefinitely, but the 72nd Emmy Awards are still holding onto 20 September.
The Oscars have been postponed for only the fourth time in their history, due to the coronavirus pandemic.
The Academy of Motion Picture Arts and Sciences announced the change on Monday, also explaining that the eligibility period has been extended to 28 February.
