MDT vs AWST: Offsets, DST and Best Call Times

MDT runs on Mountain Daylight Time (MDT) at UTC-06:00. AWST runs on Australian Western Standard Time (AWST) at UTC+08:00. That puts MDT 14 hours ahead of AWST — a difference of +14h at the current offsets.

In practice, when it is 9:00 AM in MDT it is 11:00 PM in AWST. Midnight in MDT is 2:00 PM in AWST. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert MDT to AWST time

Scheduling a call from MDT to AWST: a 10:00 AM start in MDT lands at 12:00 AM in AWST the next day, so you can confirm the slot without doing the arithmetic yourself.
Handling a +14h gap: MDT and AWST 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 AWST is 11:00 PM in MDT.
Booking travel or deliveries: tracking AWST local time against MDT keeps pickup windows and arrival estimates honest across the +14h offset.

Always state the zone abbreviation, not just the hour. "3:00 PM MDT" is unambiguous; "3 PM" across a +14h gap is not.
With a +14h gap there is no shared 9-to-5 window, so alternate the early start: one week MDT takes the early slot, the next week AWST 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 AWST (Australian Western Standard Time)

Australian Western Standard Time (AWST) is used in Western Australia. WA does not observe daylight saving time, having rejected it in multiple referendums. Perth is the most remote major city in the world.

Best time to call between MDT and AWST

With a +14h offset there is no overlap inside a normal 9 AM – 5 PM day. AWST opens at 9:00 AM AWST, which is 11:00 PM in MDT, so real-time calls need an early-morning or late-evening slot on one side.

Business hours overlap

MDT and AWST have no shared working hours because of the +14h gap. Teams need to alternate early starts or rely on asynchronous handovers.

MDT is 14 hours ahead of AWST (MDT UTC-06:00 → AWST UTC+08:00). There is no shared 9-to-5 window, so plan around an early or late slot. Remember to re-check around daylight-saving transitions.
