Why people convert EDT to Denver time
- Scheduling a call from EDT to Denver: a 10:00 AM start in EDT lands at 8:00 AM in Denver, so you can confirm the slot without doing the arithmetic yourself.
- Finding shared working hours: both EDT and Denver are inside the 9-to-5 working day between 11:00 AM and 5:00 PM EDT time (9:00 AM–3:00 PM MDT). That is roughly 6 hours of usable overlap.
- Coordinating a EDT-based team with Denver 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 EDT" is unambiguous; "3 PM" across a -2h gap is not.
- Block 11:00 AM–5:00 PM EDT as the recurring meeting window if you work primarily from EDT and need Denver colleagues present.
- Denver: Clocks fall back on Sun, Nov 1, 2026. Any meeting series spanning that date will shift by an hour in local time.
