Tomorrow night around about this time we all set our clocks forward one hour, and begin to operate on daylight savings time. I say "we all" but nearby Arizona doesn't.
Most of AZ stays on Mountain Standard Time winter and summer, but clocks on the Navajo Reservation - aka "the Big Rez" - are reset with the rest of the nation. This is likely because that reservation extends across parts of three states - UT, AZ, and NM - and it is administratively easier when the whole Navajo Nation is in the same time zone.

A fair few conservatives kvetch about switching times and advocate some form of doing away with clock changing. It never bothers me much. I notice mealtimes are a tad "off" for a few days and then everything settles down and makes sense.
Maybe one reason it doesn't bother me much is the DrsC have done a lot of overseas travel - some 120 countries at last count. There was one month we circled the globe - 24 time zones - heading west the entire time. We flew to Singapore, cruised from there to Rome and flew home. Another time cruising home across the Pacific from Asia we lost an hour every other day for over a week.
Another reason might be that we've resided in two adjacent time zones for the past 27 years, so we experience the clock adjustment four times a year instead of twice for people who live all year in one place.
----------
The other DrC claims, with some justification, that anytime we cross more than 3 time zones the adjustment period takes a day for each zone starting with the fourth. So for example flying off the U.S. west coast over the pole to Frankfurt, you've crossed 8 time zones and it takes about 8-3 = 5 days to adjust completely.
