Why people convert MST to Portugal time
- Scheduling a call from MST to Portugal: a 10:00 AM start in MST lands at 6:00 PM in Portugal, so you can confirm the slot without doing the arithmetic yourself.
- Handling a +8h gap: MST and Portugal 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 Portugal is 5:00 PM in MST.
- Keeping family and friends in sync: knowing that 8:00 PM in MST is 4:00 AM in Portugal makes it easy to avoid calling at 3 AM.
- Always state the zone abbreviation, not just the hour. "3:00 PM MST" is unambiguous; "3 PM" across a +8h gap is not.
- With a +8h gap there is no shared 9-to-5 window, so alternate the early start: one week MST takes the early slot, the next week Portugal does.
