Why the gap is always exactly 1 hour
The US Central and Eastern zones both follow the same federal daylight saving schedule — clocks change on the second Sunday of March and the first Sunday of November, the same day in both zones. Because they shift together, the difference stays locked at 1 hour throughout the year. There is no transition-week wobble like you get between regions that change their clocks on different dates.
