What time does Daylight savings time start?

Question

For us in the Central Time zone, it we are told to move our clocks ahead at 2:00 a.m. Knowing that, does the east move it ahead at 3in the morning, anf midnight in the west? Or does each time zone (with the exception of a few states) change their clocks when the time in their time zone gets to 2:00 a.m. I hope this question makes sence.

Answer 1

Daylight savings time changes occur at 2:00 am, not midnight. The change occurs at 2:00am in each individual time zone, so there are small disparities between time zones as the night progresses.

In a typical case where a one-hour shift occurs at 02:00 local time, in spring the clock jumps forward from 02:00 standard time to 03:00 DST and the day has 23 hours, whereas in autumn the clock jumps backward from 02:00 DST to 01:00 standard time, repeating that hour, and the day has 25 hours. A digital display of local time does not read 02:00 exactly, but instead jumps from (say) 01:59:59.9 either forward to 03:00:00.0 or backward to 01:00:00.0.

Answer 2

It starts at midnight since when it is midnight then it would be Sunday which is Daylight Savings Time.
