Why people convert Denver to Nigeria time

Scheduling a call from Denver to Nigeria: a 10:00 AM start in Denver lands at 5:00 PM in Nigeria, so you can confirm the slot without doing the arithmetic yourself.
Finding shared working hours: both Denver and Nigeria are inside the 9-to-5 working day between 9:00 AM and 10:00 AM MDT time (4:00 PM–5:00 PM WAT). That is roughly 1 hours of usable overlap.
Watching a live event or market open: Denver viewers need 4:00 PM in Nigeria to catch a 9:00 AM start there, and 5:00 PM if the event is anchored to Denver.

Always state the zone abbreviation, not just the hour. "3:00 PM MDT" is unambiguous; "3 PM" across a +7h gap is not.
Block 9:00 AM–10:00 AM MDT as the recurring meeting window if you work primarily from Denver and need Nigeria 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 +7h gap.
