Denver Time Zone & Daylight Saving Time
Denver uses the America/Denver time zone, US Mountain Time. Its UTC offset moves between UTC-7 (Mountain Standard Time, in winter) and UTC-6 (Mountain Daylight Time, in summer), so its gap with other cities isn't fixed all year.
For a few weeks each spring and autumn, the difference with places like London can shift by an hour, because the US and Europe change their clocks on different dates. Cities on the same US daylight saving schedule — including Chicago, New York and Toronto — keep a constant difference with Denver throughout the year, so it's mainly the international comparisons worth checking before scheduling ahead.
