Set your clock back before bedtime on Saturday, Nov. 2
October 31, 2019
Daylight saving time 2019 in Pennsylvania began at 2 a.m. on Sunday, March 10 and ends at 2 a.m. on Sunday, Nov. 3. Most people will turn their clocks back one hour when they go to bed Saturday, Nov. 2.
The change means that there will be more daylight early in the day but sunset arrives earlier in the day, so many people will leave work in the dark.
