The US Eastern Standard Time Zone is also called the GMT -5 zone. Arizona is in the Mountain Standard Time Zone which is GMT -7. So there is a two hour time difference (Daylight Saving Time not considered, see below). Since EST is east of Arizona, it is ahead in time.
Example:
If it were 6:30 pm EST, it would be 4:30 pm MST in Arizona.
Note on Arizona and DST: Most of Arizona does not observe Daylight Savings Time and stays at GMT -7 year around. However, in the Spring and Summer when DST is in effect in the other US time zones, some parts of the northeast corner of Arizona do change to DST. Then the time zone in that NE part of Arizona would be GMT -7 [+1 for DST] = GMT -6. When the EST zone also changes to Daylight Saving Time, they would then be in the GMT -4 zone. As mentioned above, the majority of Arizona would still be in the GMT -7 time zone. Therefore, during that period, there would be a threehour difference between EST and the majority of Arizona. The section of Arizona that does observe Mountain Daylight Time would continue to be two hours behind Eastern Daylight Time.
DST Example:
If it were 6:30 pm Eastern Daylight Time in the US (GMT -4), it would be 3:30 pm US Mountain Standard Time in most of Arizona (GMT -7).
For the area in NE Arizona that does observe DST, it would be US Mountain Daylight time (GMT -6). So 6:30 pm EDT would be 4:30 pm Mountain Daylight time.
