Time Conversion Guide: AWST to MDT

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

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

Why people convert AWST to MDT time

Scheduling a call from AWST to MDT: a 10:00 AM start in AWST lands at 8:00 PM in MDT the previous day, so you can confirm the slot without doing the arithmetic yourself.
Handling a -14h gap: AWST and MDT 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 MDT is 7:00 PM in AWST.
Coordinating a AWST-based team with MDT 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 AWST" 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 AWST takes the early slot, the next week MDT does.

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.

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.

Best time to call between AWST and MDT

With a -14h offset there is no overlap inside a normal 9 AM – 5 PM day. MDT opens at 9:00 AM MDT, which is 7:00 PM in AWST, so real-time calls need an early-morning or late-evening slot on one side.

Business hours overlap

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

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