How many hours apart are MST and AWST?

AWST is 15 hours ahead of MST. In everyday terms, once you know the time on one side you just add 15 hours to get the other — so a call between Denver and Perth is always 15 hours apart.

The meeting planner highlights the hours that overlap for everyone.

How does daylight saving affect MST to AWST?

The labels MST and AWST are fixed offsets, so the result on this page is always exact. One side switches between standard and summer time while the other stays put, so the real-world gap can shift by an hour for part of the year. It's worth checking which label a region is actually using before you lock in a time.

Why can you trust this MST to AWST converter?

Every conversion here is calculated from the IANA time zone database — the same source your phone, computer, and browser rely on. Plenty of tools hard-code a single offset, which quietly goes wrong whenever a region changes its rules or flips for daylight saving. We follow the real rules instead, so MST to AWST stays accurate for today and for any past or future date you type in.

Do MST or AWST use daylight saving time?

Why might the real-world MST–AWST difference change during the year?
