Why people convert Denver to NST time

Scheduling a call from Denver to NST: a 10:00 AM start in Denver lands at 12:30 PM in NST, so you can confirm the slot without doing the arithmetic yourself.
Finding shared working hours: both Denver and NST are inside the 9-to-5 working day between 9:00 AM and 2:30 PM MDT time (11:30 AM–5:00 PM NST). That is roughly 5 hours 30 minutes of usable overlap.
Coordinating a Denver-based team with NST 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 MDT" is unambiguous; "3 PM" across a +2h 30m gap is not.
Block 9:00 AM–2:30 PM MDT as the recurring meeting window if you work primarily from Denver and need NST colleagues present.
Denver: Clocks fall back on Sun, Nov 1, 2026. Re-check this page after that date because the offset changes and so does the +2h 30m gap.
