Current Time in Denver

Summary

This tool shows the current local time in Denver, Colorado, USA using the America/Denver IANA timezone. It automatically accounts for Mountain Standard Time (MST, UTC-7) in winter and Mountain Daylight Time (MDT, UTC-6) during daylight saving, so the displayed offset is always accurate. The clock updates every second directly in your browser with no server calls.

How it works

1. Your browser reads the current UTC timestamp.
2. The Intl.DateTimeFormat API converts it to the America/Denver timezone.
3. The live clock updates every second on your screen.
4. The UTC offset (MST or MDT) is derived from the same API and shown alongside the time.
5. Date, day of the week, and week number are displayed below the clock for full context.
