About these time zones
MST. This page uses Denver, which is MST (UTC-7) in winter and MDT (UTC-6) in summer. Most of Arizona stays on MST all year, so in summer Phoenix matches Pacific Time rather than Denver.
EST. Eastern Time is EST (UTC-5) in winter and EDT (UTC-4) from the second Sunday in March to the first Sunday in November. It covers New York, Toronto, Miami and most of the US East Coast.
Overlap. Meetings starting between 9:00 AM and 2:00 PM MST land inside a 9 to 5 working day in both zones.
