Does Denver observe daylight saving time?

Yes. Denver runs on UTC-7 in winter and UTC-6 in summer. The next change is on 2026-11-01, when clocks go back by 60 minutes.

Does Dubai observe daylight saving time?

No. Dubai stays on UTC+4 all year, so its clocks never move.

It is 22:00 in Dubai, on the same calendar date. That holds for the current offsets; it shifts by an hour around the daylight saving dates listed above.

Which time zones do Denver and Dubai use?

Denver uses America/Denver, currently UTC-6 (MDT), and Dubai uses Asia/Dubai, currently UTC+4 (GST). Those identifiers are the ones to use in code — abbreviations are ambiguous and offsets change.
