I just realized something relatively minor but thought I'd share for anyone traveling over the next few weeks, as I am.
North America “springs forward” into Daylight Savings Time this Sunday, the 13th. (OK Arizona… we see you.) But Europe is two weeks behind that schedule, shifting on the 27th. That means that the time difference will be an hour less for those two weeks.
(And in the fall, they’ll “fall back” a week before us. That should add an hour to the time change—I think…)
