MST to EET Converter

Standard business hours (9 AM–5 PM, Mon–Fri) in Mountain Time and Eastern European Time don't overlap on the same weekday. Eastern European Time is 9 hours ahead of Mountain Time.

With some flexibility, there’s a workable window outside standard hours:

• 7 AM–11 AM in Mountain Time (4 PM–8 PM in Eastern European Time) — suggest 9:00 AM Mountain Time (6:00 PM Eastern European Time).

This means an early start or late finish for one side, but it’s a reasonable slot for a one-off meeting.

Mountain Time is also known as MST, or MDT. To call United States, dial +1.

Eastern European Time is also known as EET, or EEST. To call Finland, dial +358.

Eastern European Time is approximately 4,950 miles northeast of Mountain Time.

Both zones observe daylight saving time, but they transition on different dates.

Mountain Time: next transition on Sunday, November 1, 2026.

Eastern European Time: next transition on Sunday, October 25, 2026.

For approximately 7 days between transitions, the offset between Mountain Time and Eastern European Time differs from its typical value. Recurring meetings during this window will shift by one hour.

See the daylight saving time page for transition dates across every time zone.
