Why people convert MST to Lisbon time
- Scheduling a call from MST to Lisbon: a 10:00 AM start in MST lands at 6:00 PM in Lisbon, so you can confirm the slot without doing the arithmetic yourself.
- Handling a +8h gap: MST and Lisbon 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 Lisbon is 5:00 PM in MST.
- Coordinating a MST-based team with Lisbon 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 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 Lisbon does.
- Lisbon: Clocks fall back on Sun, Oct 25, 2026. Any meeting series spanning that date will shift by an hour in local time.
