Current Time in Denver, United States — Live Clock

Time zone facts for Denver

IANA time zone: America/Denver
Standard offset: UTC−7
Daylight saving: observed — the offset moves to UTC−6 while DST is active (the live clock above already reflects today's status).
January / July offset: UTC−7 / UTC−6
Offset as of September 2026: UTC−6 — daylight saving in effect
Next clock change: clocks go back 1 hour on Sunday, November 1, 2026 (local date), moving the offset from UTC−6 to UTC−7

How Denver's offset moves through the year

Denver keeps two offsets: UTC−7 in January and UTC−6 in July. The clocks move between them twice a year, and each move changes the difference between Denver and every place that does not move at the same instant. As of September 2026, the offset is UTC−6, so daylight saving is in effect.

The coming cycle, derived from the IANA time zone database as of September 2026: the clocks next go back 1 hour on Sunday, November 1, 2026 (Denver local date), taking the offset from UTC−6 to UTC−7. The change after that comes 133 days later, on Sunday, March 14, 2027, when the clocks go forward 1 hour and the offset returns from UTC−7 to UTC−6. Those 133 days are the standard-time part of the year for Denver.

Read those two dates alongside the partner's dates for any city you work with. If the partner does not observe daylight saving, the gap to it changes on exactly these two dates. If it does, the gap changes only where the two calendars disagree — not at all when both sides switch at the same instants, otherwise on every date where one side has shifted and the other has not yet. The table below works that out for the reference cities.

Set against the reference cities, as of September 2026: Denver's next change comes 7 days after London's (Sunday, October 25, 2026, London date) and 2 hours after New York's (Sunday, November 1, 2026, New York date). Tokyo has no change of its own scheduled within the next 15 months, so its gap to Denver moves on Denver's dates alone. Which city moves first is what shapes each of the mismatch windows set out below.

The gap to London, New York, and Tokyo across the year

The differences below were computed at build time by scanning the coming twelve months of the IANA time zone database for each pair, locating every instant at which either city changes its clocks, and reading the gap on each side of it. "As of September 2026" is the gap today; "over the year" is the full range the pair takes before the same month comes round again, from Denver's point of view.

Denver's difference from each reference city, as of September 2026. Derived from the IANA time zone database at build time.
Reference	Denver is, as of September 2026	Over the coming year	Why
London	7 hours behind	6 hours behind to 7 hours behind	both change clocks, on different dates
New York	2 hours behind	1 hour behind to 3 hours behind (3 distinct values)	both change clocks, hours apart
Tokyo	15 hours behind	15 hours behind to 16 hours behind	only Denver changes its clocks

None of the three gaps holds still for the whole year. The mechanism in each case is set out below, with the exact instants at which the gap moves.

Denver and London

As of September 2026, Denver is 7 hours behind London. Both Denver and London change their clocks, but not at the same instants. Between one side's transition and the other's, only one shift has happened, so the gap briefly holds a value it holds only inside these mismatch windows. The gap changes 4 times in the coming twelve months; the briefest such window lasts 7 days, from October 24, 2026 to November 1, 2026 (Denver dates), during which Denver is 6 hours behind London.

From Saturday, October 24, 2026 at 7:00 PM (Denver time), when London changes clocks: Denver is 6 hours behind London.
From Sunday, November 1, 2026 at 1:00 AM (Denver time), when Denver changes clocks: Denver is 7 hours behind London.
From Sunday, March 14, 2027 at 3:00 AM (Denver time), when Denver changes clocks: Denver is 6 hours behind London.
From Saturday, March 27, 2027 at 7:00 PM (Denver time), when London changes clocks: Denver is 7 hours behind London.

Each of those windows is opened by one city's change and closed by the other's. The first, from October 24, 2026 to November 1, 2026 (Denver dates), opens when London's clocks go back and closes 7 days later when Denver's go back. In between, Denver is on daylight time and London on standard time, so Denver is 6 hours behind London against 7 hours behind on either side of it. The second, from March 14, 2027 to March 27, 2027 (Denver dates), opens when Denver's clocks go forward and closes 14 days later when London's go forward. In between, Denver is on daylight time and London on standard time, so Denver is 6 hours behind London against 7 hours behind on either side of it. Which city moves first differs from window to window, and the longest of them lasts 14 days.

Denver and New York

As of September 2026, Denver is 2 hours behind New York. Both Denver and New York change their clocks, but not at the same instants — each of Denver's changes falls within hours of New York's. Between one side's transition and the other's, only one shift has happened, so the gap briefly holds a value it holds only inside these mismatch windows. The gap changes 4 times in the coming twelve months; the briefest such window lasts 2 hours, from Sunday, November 1, 2026 at 12:00 AM MDT to Sunday, November 1, 2026 at 1:00 AM MST (Denver time), during which Denver is 1 hour behind New York.

From Sunday, November 1, 2026 at 12:00 AM MDT (Denver time), when New York changes clocks: Denver is 1 hour behind New York.
From Sunday, November 1, 2026 at 1:00 AM MST (Denver time), when Denver changes clocks: Denver is 2 hours behind New York.
From Sunday, March 14, 2027 at 12:00 AM MST (Denver time), when New York changes clocks: Denver is 3 hours behind New York.
From Sunday, March 14, 2027 at 3:00 AM MDT (Denver time), when Denver changes clocks: Denver is 2 hours behind New York.

Each of those windows is opened by one city's change and closed by the other's. The first, from Sunday, November 1, 2026 at 12:00 AM MDT to Sunday, November 1, 2026 at 1:00 AM MST (Denver time), opens when New York's clocks go back and closes 2 hours later when Denver's go back. In between, Denver is on daylight time and New York on standard time, so Denver is 1 hour behind New York against 2 hours behind on either side of it. The second, from Sunday, March 14, 2027 at 12:00 AM MST to Sunday, March 14, 2027 at 3:00 AM MDT (Denver time), opens when New York's clocks go forward and closes 2 hours later when Denver's go forward. In between, New York is on daylight time and Denver on standard time, so Denver is 3 hours behind New York against 2 hours behind on either side of it. New York is the first to move in every window, and the longest of them lasts 2 hours.

Denver and Tokyo

As of September 2026, Denver is 15 hours behind Tokyo. Denver changes its clocks for daylight saving and Tokyo does not. Each Denver transition therefore moves the gap by the full size of that shift, and nothing ever moves it back except the next Denver transition. The gap changes twice in the coming twelve months, always on Denver's dates — Tokyo's calendar plays no part.

From Sunday, November 1, 2026 at 1:00 AM (Denver time), when Denver changes clocks: Denver is 16 hours behind Tokyo.
From Sunday, March 14, 2027 at 3:00 AM (Denver time), when Denver changes clocks: Denver is 15 hours behind Tokyo.

Ranked by how many of the 365 scanned days each gap spends at its most common value, from Denver's point of view: New York 365 (2 hours behind), London 344 (7 hours behind), and Tokyo 232 (15 hours behind). The two kinds of movement are not alike. The gap to London changes 4 times in the year yet is away from its usual value for only 21 days in total, because each departure ends as soon as the other city catches up. The gap to Tokyo changes only twice, but each change stands until the next one, so it spends 133 days away from its most common value.

Working hours that overlap

Assume a 9:00 AM to 5:00 PM working day in Denver and the same in each reference city. The overlap is then a plain consequence of the gap, and it changes whenever the gap does — so where a pair takes more than one gap during the year, both readings are given. As of September 2026:

London: 1 hour — 9:00 AM to 10:00 AM in Denver, which is 4:00 PM to 5:00 PM in London. When Denver is 6 hours behind London — the rest of the year — the overlap is 2 hours — 9:00 AM to 11:00 AM in Denver, which is 3:00 PM to 5:00 PM in London.
New York: 6 hours — 9:00 AM to 3:00 PM in Denver, which is 11:00 AM to 5:00 PM in New York. When Denver is 1 hour behind New York — at other times of the year — the overlap is 7 hours — 9:00 AM to 4:00 PM in Denver, which is 10:00 AM to 5:00 PM in New York. When Denver is 3 hours behind New York — at other times of the year — the overlap is 5 hours — 9:00 AM to 2:00 PM in Denver, which is 12:00 PM to 5:00 PM in New York.
Tokyo: none at any gap the pair takes during the year — a 9:00 AM to 5:00 PM day in Denver never meets a 9:00 AM to 5:00 PM day in Tokyo.

The 9-to-5 window is a convention, not a fact about anyone's hours. The Meeting Planner takes each participant's actual working hours and evaluates the overlap for the specific date, so a slot chosen in one season is still checked against the other side's clock in the next.

Zone-to-zone converter pages for Denver

MST — Mountain Standard Time (North America). Denver is the anchor city for MST on this site; the same zone is written MDT (Mountain Daylight Time) while daylight saving is active, and in everyday use "MST" means Denver's time, whichever of MST/MDT is in force. The same letters also mean: Mountain time as kept year-round in Phoenix, which does not observe DST. Each converter page states which meaning it uses.

MST to EST — US Mountain and US Eastern.

The one corridor anchored on MST, as of September 2026, leads to a zone whose switches fall within hours of Denver's (EST), so the gap leaves its usual value for at most 2 hours at a time.
