What Arizona and EST mean here
Most of Arizona stays on MST (UTC−7) all year and doesn't use daylight saving time. In winter that matches Denver (Mountain Time); in summer it matches Los Angeles (Pacific Time). The Navajo Nation in northeastern Arizona is the exception and does change its clocks.
EST (Eastern Standard Time, UTC−5) is the winter time in New York, Washington, Atlanta, Miami and Toronto. From March 8 to November 1, 2026 those places use EDT (Eastern Daylight Time, UTC−4) instead. Most people who write "EST" mean "Eastern Time, whatever the clocks say today", so this converter follows the clocks in New York and switches between EST and EDT on the right days.
