EST: Eastern Time · EST time now
Strictly, EST is the winter offset (UTC−5). From March to November the same clocks run on EDT (UTC−4). Most people who search "EST" mean whatever the US East Coast clocks show, so this page follows America/New_York.

MST: Mountain Time · MST time now
Arizona (America/Phoenix) stays on MST all year, so for part of the year it matches Pacific Time instead of Denver.
