FAQ
What time is it in Denver right now?
Denver is on UTC-7 in winter and UTC-6 during daylight saving time in summer, which is 7 hours behind UTC. So when it is 12:00 UTC, the local time in Denver is 05:00 in winter and 06:00 in summer. The live clock at the top of this page applies that offset to the current moment and refreshes every second.
What time zone is Denver in?
Denver uses the America/Denver time zone, shown as MDT. Denver uses UTC-7 in winter (standard time) and shifts to UTC-6 in summer when daylight saving time is active. The "compare to your time zone" section above converts any Denver time into your own local time instantly.
Does Denver observe daylight saving time?
Yes — Denver does observe daylight saving time. Clocks move forward one hour in summer, taking Denver from UTC-7 to UTC-6, and back again for winter. That means the difference between Denver and any place holding a fixed offset changes by an hour for part of the year. This page reads the current offset from the America/Denver zone data every time it loads, so the clock, the converter and the call window above are correct for today's date without you tracking the changeover.
How do I convert Denver time to my time zone?
Convert Denver time by taking its UTC-7 offset and applying the difference to your own: subtract Denver's offset from UTC to get the UTC time, then add your own offset. For example, 09:00 in Denver is 16:00 UTC. The converter above does this automatically after detecting your device's time zone, and the World Clock meeting planner lays several cities out on one colour-coded 24-hour grid.
What is the dialing code for Denver?
The dialing code for Denver is +1. To call from abroad, dial +1 before the local number. The card at the top of this page shows it alongside the live local time so you can check it is a reasonable hour before you call.
What are the best hours to call Denver?
Standard business hours in Denver — 9:00 to 17:00 local time — correspond to 16:00 to 00:00 UTC while standard time is in effect, shifting one hour earlier in UTC terms during daylight saving. Convert that UTC window into your own zone to find the overlap. The "best time to call" line above does this for you, using waking hours of roughly 8am–9pm on both ends so neither side is called at night.
