Aurora, Colorado operates on Mountain Time (MT), which is UTC−7 during standard time and UTC−6 during daylight saving time. This aligns with most of Colorado, including Denver.
Colorado sits entirely within the Mountain Time Zone. Unlike some states that span multiple time zones, Colorado doesn't have exceptions. However, nearby states like Kansas and Nebraska observe Central Time (CT), creating a one-hour difference with Aurora.
The state adopted daylight saving time in 2007, shifting clocks forward one hour. Before this, Colorado didn't observe daylight saving, which caused confusion for travelers and businesses.
| Time Zone | Abbreviation | UTC Offset (Standard) | UTC Offset (Daylight) |
|---|---|---|---|
| Eastern Time | ET | UTC−5 | UTC−4 |
| Central Time | CT | UTC−6 | UTC−5 |
| Mountain Time | MT | UTC−7 | UTC−6 |
| Pacific Time | PT | UTC−8 | UTC−7 |
Travelers often confuse Aurora's time with neighboring states. For example, Kansas City, KS (CT) is one hour ahead of Aurora. Scheduling meetings or flights requires checking both locations' times.
Businesses with remote teams in different time zones must account for the offset. A 9 AM meeting in Aurora is 10 AM in Kansas City.
Another myth is that mountain towns near the Utah border observe Pacific Time. In reality, all of Colorado uses Mountain Time.
If it's 3 PM in Aurora, what time is it in Kansas City, KS? Since Kansas City is on CT (one hour ahead), it's 4 PM there. Conversely, if it's noon in Phoenix, AZ (PT, two hours behind), it's 2 PM in Aurora.
I once scheduled a call with a client in Wichita, KS, assuming we were on the same time. When they joined an hour late, I realized my mistake-Wichita is on CT, while Aurora is on MT.
Aurora, CO operates on Mountain Time, matching most of Colorado. Nearby states like Kansas and Nebraska observe Central Time, creating a one-hour difference. Daylight saving time shifts Aurora's clock forward. Always verify time zones when traveling or scheduling across state lines.
