What is 12 AM EST in MST?
12 AM Eastern time is 10 PM Mountain the day before.
Mountain time is 2 hours behind Eastern time, so subtract 2 hours. This holds all year: in summer, 12 AM ETD is 10 PM MTD. Arizona (except the Navajo Nation) stays on Mountain Standard Time all year, so in summer Arizona matches Pacific time.
