It is 7:45 am in Atlantic/Bermuda

Atlantic/Bermuda is the IANA identifier for the time zone of Bermuda in Bermuda. It is running at UTC-3 right now, abbreviated ADT, and the local date is Friday, September 25, 2026. The zone is on its summer offset at the moment.

What time is it in Atlantic/Bermuda right now

7:45 am on Friday, September 25, 2026, as this page was served, which in 24 hour form is 07:45. The clock above ticks on from there in your own browser. The offset is a whole 3 hours behind UTC, so a UTC timestamp converts here by changing the hour and leaving the minutes exactly as they are.

33 other zones read UTC-3 at this instant. They are interchangeable as a clock reading today and not as an identifier: storing UTC-3 instead of Atlantic/Bermuda throws away the rule that decides what they all do at the next transition.

The UTC offset of Atlantic/Bermuda

An offset of UTC-3 names the meridian 45.0 degrees west. Hamilton, Bermuda actually sits at 64.78 degrees west, which is 19.8 degrees west of it, so the sun there runs about 79 minutes behind the clock before daylight saving is even considered. Zone boundaries are drawn by borders and by convenience, not by longitude, and this is the size of the gap that produces.

Because this zone moves its clocks, UTC-3 is only today's answer. It runs at UTC-4 for the winter part of the year and UTC-3 for the summer part, a difference of 1 hour, and any gap memorised against it is wrong for part of the year.

Daylight saving in Atlantic/Bermuda

Atlantic/Bermuda does observe daylight saving. The next change is on November 1, 2026: at 1:00 am local the clocks go back, and UTC-3 becomes UTC-4. That hour is repeated, so every reading inside it happens twice, which is why a wall clock time in this zone is not always a single instant.

Every clock change the database has for this zone in 2025, 2026 and 2027, with the exact local reading either side of the jump.

How the offset of Atlantic/Bermuda has changed since 1970

Read on 1 January and 1 July of each year, which is the cheapest pair of samples that shows both the winter offset and whether the clocks moved that summer. The zone has passed through 2 distinct eras in that time and has used 2 different offsets: UTC-4, UTC-3. Its current behaviour has held since 1974. A rule change that began and ended between July and the following January is invisible to this sampling, so the table is a shape rather than a complete edit history.

The earliest summer shift this sampling sees here is 1974, and the zone has kept moving its clocks since. The dates the change falls on have moved several times even where the rule has not.

Countries and regions that use Atlantic/Bermuda

One country uses Atlantic/Bermuda: Bermuda, which keeps this as its only time zone and has a population of about 64,000.

Cities in the Atlantic/Bermuda time zone

This site does not yet carry a city page inside Atlantic/Bermuda, so the readings here are computed for the identifier itself and anchored at Hamilton, Bermuda. That costs nothing in accuracy: an offset is a property of the zone, not of a settlement, so the clock above is right for every point inside it. The city index lists the 6,338 places that do have their own page.

The sun against the clock in Atlantic/Bermuda

Worked out for Hamilton, Bermuda, the capital of a country that keeps the zone, at 32.29 degrees north, 64.78 degrees west. The sun rises at 7:09 am and sets at 7:12 pm, giving 12 hours 2 minutes of daylight. Solar noon, the moment the sun is highest, falls at 1:11 pm, which is 71 minutes after clock noon.

That gap is the whole argument about where zone lines belong, in one number. It is made of three things: Hamilton, Bermuda sitting 19.8 degrees west of the UTC-3 meridian, the equation of time, which today runs 8.4 minutes ahead of mean time, and the hour of daylight saving currently in force.

Convert Atlantic/Bermuda to another time zone

The converter is keyed on the abbreviations people type rather than on identifiers. Atlantic/Bermuda is at UTC-3 right now, the same reading as AST, so these pages answer the same question for it today. They will diverge if the two zones ever adopt different daylight saving rules, which is exactly why the identifier is the thing worth storing.

Questions about Atlantic/Bermuda

What time is it in Atlantic/Bermuda right now?

7:45 am on Friday, September 25, 2026, as this page was served. The clock at the top of the page ticks on from there.

Bermuda.

Why store Atlantic/Bermuda instead of UTC-3?

Because the offset is an output and the identifier is the input. This zone alone has two offsets in a year, and 33 other zones share its current reading while carrying different rules. A record storing UTC-3 cannot tell them apart; a record storing Atlantic/Bermuda keeps working through every future rule change.
