Why people convert Denver to Russia time

Scheduling a call from Denver to Russia: a 10:00 AM start in Denver lands at 7:00 PM in Russia, so you can confirm the slot without doing the arithmetic yourself.
Handling a +9h gap: Denver and Russia 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 Russia is 6:00 PM in Denver.
Keeping family and friends in sync: knowing that 8:00 PM in Denver is 5:00 AM in Russia 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 +9h gap is not.
With a +9h gap there is no shared 9-to-5 window, so alternate the early start: one week Denver takes the early slot, the next week Russia does.
