Why people convert Denver to Beijing time

Scheduling a call from Denver to Beijing: a 10:00 AM start in Denver lands at 12:00 AM in Beijing the next day, so you can confirm the slot without doing the arithmetic yourself.
Handling a +14h gap: Denver and Beijing 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 Beijing is 11:00 PM in Denver.
Keeping family and friends in sync: knowing that 8:00 PM in Denver is 10:00 AM in Beijing makes it easy to avoid calling at 3 AM.

Always state the zone abbreviation, not just the hour. "3:00 PM MDT" 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 Denver takes the early slot, the next week Beijing does.
Denver: Clocks fall back on Sun, Nov 1, 2026. Re-check this page after that date because the offset changes and so does the +14h gap.
