UTC vs MST — What You Need to Know

UTC is the global time standard with no DST. MST (UTC-7) covers the Rocky Mountain states. In summer, MST shifts to MDT (UTC-6) — except Arizona, which stays at UTC-7 year-round.

15:00 UTC is 8:00 AM MST — a common server log anchor for Mountain Time operations.

Frequently Asked Questions

How many hours is UTC ahead of MST?

UTC is 7 hours ahead of MST (Mountain Standard Time, UTC-7) in winter. During US Daylight Saving Time (MDT, UTC-6), UTC is only 6 hours ahead.

What is 12:00 UTC in MST?

12:00 UTC is 5:00 AM MST (UTC-7) in winter, or 6:00 AM MDT (UTC-6) in summer. Subtract 7 hours from UTC for MST, or 6 hours for MDT.

How do I convert UTC to Mountain Time?

To convert UTC to MST (winter): subtract 7 hours. To convert to MDT (summer, March–November): subtract 6 hours. Example: 15:00 UTC = 8:00 AM MST = 9:00 AM MDT.

What is Arizona's UTC offset?

Arizona (except the Navajo Nation) uses MST (UTC-7) year-round and does not observe Daylight Saving Time. So Arizona is always UTC-7, regardless of season.
