That time of year again. No, not Santa, not exactly

I don't think it was specifically April 24 but "about April 24" as the OP stated. And was roughly around the date that railroads traditionally issued new timetables at the change from Standard to Daylight Time.

That is interesting and I never thought about it.. But then I realized RRs did not start using Daylight time until the mid 50s and the snowbirds existed well before that

April 25th is the latest date that Easter can fall. Not sure if that's the reason, but that's something that happens then.
