A team split between MT and ET is at work together for 6 hours a day.

Taking 9 AM to 5 PM on each clock as the working day, both zones are at work from 9:00 AM to 3:00 PM MST (11:00 AM to 5:00 PM EST).

One day on MST clocks, with the same moments read on EST clocks underneath.

A team spread across two time zones has fewer chances to notice someone drifting away. TeamPredict reads public LinkedIn signals to flag resignation risk early, wherever people work.

The gap between MST and EST stays at 2 hours all year.

Both zones are in the United States and move their clocks on the same two Sundays, so the gap holds.

Each bar is one calendar year, January on the left. Days are coloured by the gap between MST and EST.

These are the clock changes of both zones in 2026 and 2027.

Mountain Time is MST (UTC−7) in winter and MDT (UTC−6) in summer, and this page follows Denver, which changes its clocks. Most of Arizona stays on MST all year. The clock reads MDT right now. It moves its clocks forward at 2:00 AM on the second Sunday in March and back at 2:00 AM on the first Sunday in November.

Eastern Time is EST (UTC−5) in winter and EDT (UTC−4) in summer. People write EST all year, and this page does too; the clock reads EDT right now. It moves its clocks forward at 2:00 AM on the second Sunday in March and back at 2:00 AM on the first Sunday in November.

The time zone converter reads one moment on up to 12 clocks, the military time converter turns 24-hour times into AM and PM, and the time duration calculator measures the hours between two moments.

Here are four questions about MST to EST, answered.

What is 9 AM MST in EST?
9:00 AM MST is 11:00 AM EST, and 5:00 PM MST is 7:00 PM EST.
What is the time difference between MST and EST?
Mountain Time (MST) is 2 hours behind Eastern Time (EST). The gap between MST and EST stays at 2 hours all year. Both zones are in the United States and move their clocks on the same two Sundays, so the gap holds. The next clock change is Sunday, November 1, 2026.
Does the gap between MST and EST ever change?
Only briefly. On Sunday, November 1, 2026, each zone moves at 2:00 AM by its own clock, so for 2 hours the gap is 1 hour instead of 2 hours. The rest of the year it stays 2 hours. The United States moves its clocks on these days. In 2026: Mar 8 and Nov 1. In 2027: Mar 14 and Nov 7.
What is a good time for a meeting between MST and EST?
9:00 AM to 3:00 PM MST (11:00 AM to 5:00 PM EST) is 6 hours when both sides are inside 9 AM to 5 PM, so a meeting there starts and ends in everyone's normal day.
