You do know that the “events” aren’t real, right? 

It would be like if, 2000 years from now, they had a holiday celebrating Tony Stark and friends saving New York City (not the date of the Avengers release, the “real” date of the battle.)

It doesn’t really matter if the numerical date of the holiday is a bit wibbly-wobbly.
