When did Arizona stop daylight savings time?

Answer 1

The practice of Daylight Saving Time in Arizona got started in 1918 and lasted until 1919. A few decades later when almost all of the US and Canada were observing "War Time" during World War II, from February 1942 to September 1945 (called "Peace Time" from August 14 to September 30, 1945), Arizona started it at the same time as the rest of the country, but they ended up switching back to standard time for three months in early 1944, then in October 1944 they switched to standard time and stayed there. The only time changes in Arizona since then were for daylight saving time in 1967. The Uniform Time Act of 1966, which transferred control of when and where DST would begin and end from the state governments to the federal government, had just taken effect. Although it requires states that observe DST to do so during the specified period (which changed twice since 1966), states still have the choice of opting out of the practice. However, Arizona failed to pass the required legislation in time that first year.

Answer 2

The last time daylight saving time was observed throughout Arizona was 1967, after the Uniform Time Act of 1966 took effect and before Arizona exercised its right to opt out.

Answer 3

Arizona does not observe daylight saving time, so it does not change its clocks twice a year like most states in the U.S. The state made the decision to stop observing daylight saving time in 1968.
