Agent & Soldier - The 1949 Endgame Branch Timeline

Christopher Markus says Steve Rogers went back in time to "roughly '48". Stephen McFeely says "1948", sometime after the second season of Agent Carter (which finishes in July 1947). However, the film's shooting script, written by them, explicitly says "1949", and that Rogers is "112" (biologically). Rogers is biologically 38.7 at the time of his time travel, so lived a further 73.3-74.3 years back to October 30, 2023 (see 2023 references), meaning he arrived back in time between approximately June 27, 1949 and June 26, 1950. Assuming the earliest possible, to be as close as possible to the "1948" comments, Rogers can be taken to have traveled to June 27, 1949.This is why it starts on that last date.
