Time Zones

The concept of time zones was originally conceived as being 15 degrees wide to denote a one-hour variance in the mean solar time. However, some international time zones were adjusted to shorter intervals. Therefore, the world operates today with 30 time zones across the globe instead of 24.

Arizona (unlike the other western states and the Navajo Nation) remains on solar time year round. Arizona does not change the clocks ahead to daylight savings with changes delays the time of sunset by one hour from March to November.
