MDT to GST Time Difference – Complete Guide

MDT runs on Mountain Daylight Time (MDT) at UTC-06:00. GST runs on Gulf Standard Time (GST) at UTC+04:00. That puts MDT 10 hours ahead of GST — a difference of +10h at the current offsets.

In practice, when it is 9:00 AM in MDT it is 7:00 PM in GST. Midnight in MDT is 10:00 AM in GST. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert MDT to GST time

Scheduling a call from MDT to GST: a 10:00 AM start in MDT lands at 8:00 PM in GST, so you can confirm the slot without doing the arithmetic yourself.
Handling a +10h gap: MDT and GST have no overlap inside a normal 9-to-5 day, so real-time meetings need an early-morning or late-evening slot on one side. 9:00 AM in GST is 7:00 PM in MDT.
Coordinating a MDT-based team with GST contacts: quoting times in the other side's local clock — not your own — removes the single biggest source of missed meetings.

Always state the zone abbreviation, not just the hour. "3:00 PM MDT" is unambiguous; "3 PM" across a +10h gap is not.
With a +10h gap there is no shared 9-to-5 window, so alternate the early start: one week MDT takes the early slot, the next week GST does.

About MDT (Mountain Daylight Time)

Mountain Daylight Time (MDT) is observed during summer months in the Mountain Time Zone, except in Arizona which stays on MST year-round. MDT aligns with Central Standard Time (CST) at UTC-06:00.

About GST (Gulf Standard Time)

Gulf Standard Time (GST) is the time zone used in the United Arab Emirates, Oman, and other Gulf states. GST does not observe daylight saving time. Dubai and Abu Dhabi, major international business and tourism hubs, operate on GST.

Best time to call between MDT and GST

With a +10h offset there is no overlap inside a normal 9 AM – 5 PM day. GST opens at 9:00 AM GST, which is 7:00 PM in MDT, so real-time calls need an early-morning or late-evening slot on one side.

Business hours overlap

MDT and GST have no shared working hours because of the +10h gap. Teams need to alternate early starts or rely on asynchronous handovers.

MDT is 10 hours ahead of GST (MDT UTC-06:00 → GST UTC+04:00). There is no shared 9-to-5 window, so plan around an early or late slot. Remember to re-check around daylight-saving transitions.
