The End of Daylight Saving Time in 2019


On 2 a.m. today, we turned our clocks back one hour, marking the end of daylight saving time (DST) in 2019.

Postcard US-4002383 to Russia shows Hoover Dam with Arizona side on the right and Nevada side on the left, with the state boundary running across the dam.


Since Arizona is in the Mountain Time Zone (GMT-7) whereas Nevada is in the Pacific Time Zone (GMT-8), Arizona is one hour ahead. Therefore, if you stand across the state line on the dam right now, your left-side of body and your right-side of body will be in different time zones with one-hour time difference.

However, because Nevada observes DST while Arizona does not, during the summer there is no time difference. Interesting? Confusing? Next time when you visit the dam, pay attention to the clocks on the two intake towers; you will see.

Daylight saving time will return at 2:00 AM on Sunday, March 8, 2020.
