Arizona is on what is called Mountain Time, abbreviated MT, or more specifically Mountain Standard Time (MST). Most of the state does not use Mountain Daylight Time (MDT) as other states do.
It is on Mountain Standard Time (MST) year round. Since MST is equivalent to PDT, Arizona is on the same time as California from mid-March to early November. During the winter months, from early November to early March, Arizona is on MST, which means it would be on the same time as Colorado during those months, which is also on MST.

Most of Arizona does not observe daylight savings time, so generally there is no need to change your clocks back or forward. This can cause some confusion when dealing with other states that DO use daylight savings time. During the colder months, all of the nation observes standard time. During this time, Arizona time is the same as Mountain Standard Time (MST), which is the same as Denver, Colorado; 2 hours earlier than Eastern Standard Time (EST).
In the warmer months, most of the country observes daylight savings time. During this time, areas observing daylight savings set their clocks ahead one hour. Arizona time would then coincide with Pacific Daylight Time (PDT), the same as California, which is three hours earlier than Eastern Daylight Time (EDT), the time zone used in New York.
* All Navajo Nation lands in Arizona do observe daylight savings time (Mountain Daylight Time or MDT). Navajo Nation land in Arizona comprises 15,881 square miles. This is equivalent to nearly 14% of Arizona's total area.

Arizona does not observe Daylight Saving Time, so there is a 1-hour time difference between Arizona and Florida. When Florida is on Daylight Saving Time, it is 3 hours ahead of Arizona. When Florida is on Standard Time, it is 2 hours ahead of Arizona.
Arizona does not observe Daylight Saving Time, while Washington DC does. This means that during Daylight Saving Time, there is a 2-hour time difference between Washington DC and Arizona (with Arizona being 2 hours behind). However, when Daylight Saving Time is not in effect, there is a 3-hour time difference between the two (with Arizona being 3 hours behind).
