It is all politics at thr behesy of the Chamber of Commerce.Indiana was originally CST which made us closer to sun time .But the business people eanted to be in step with New York not Chicago.So Indiana is already one hour ahead of sun time,the “daylight “farce put us two hours ahead.
It was better when the “dayligjt saving” period was shorter
DST March 21 to Sept 21 if you must have it.
It’s interesting DST is now pushed back into the winter, though to be symmetric around the winter solstice, it would actually go to middle of February. I think some of the microwave towers haven’t caught up with that central-eastern line, because my phone, which is old (4g),runs an hour off through there, which is confusing when you travel.
