It is 8:10 am in America/Havana

America/Havana is the IANA identifier for the time zone of Havana in Cuba. It is running at UTC-4 right now, with no letter abbreviation in common use, and the local date is Saturday, September 26, 2026. The zone is on its summer offset at the moment.

What time is it in America/Havana right now

8:10 am on Saturday, September 26, 2026, as this page was served, which in 24 hour form is 08:10. The clock above ticks on from there in your own browser. The offset is a whole 4 hours behind UTC, so a UTC timestamp converts here by changing the hour and leaving the minutes exactly as they are.

47 other zones read UTC-4 at this instant. They are interchangeable as a clock reading today and not as an identifier: storing UTC-4 instead of America/Havana throws away the rule that decides what they all do at the next transition.

The UTC offset of America/Havana

An offset of UTC-4 names the meridian 60.0 degrees west. Havana, Cuba actually sits at 82.37 degrees west, which is 22.4 degrees west of it, so the sun there runs about 89 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-4 is only today's answer. It runs at UTC-5 for the winter part of the year and UTC-4 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 America/Havana

America/Havana does observe daylight saving. The next change is on November 1, 2026: at 12:00 am local the clocks go back, and UTC-4 becomes UTC-5. 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 America/Havana 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 3 distinct eras in that time and has used 2 different offsets: UTC-5, UTC-4. Its current behaviour has held since 2007. 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 1970, 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.

Cities in the America/Havana time zone

The 31 cities this site covers inside America/Havana, each with a live clock and today's sunrise and sunset worked out from its own coordinate. They share an identifier, so they share a clock reading to the minute, and they do not share a sunrise: that is set by latitude and longitude.

The sun against the clock in America/Havana

Worked out for Havana, Cuba, the city this site covers inside the zone, at 23.11 degrees north, 82.37 degrees west. The sun rises at 7:20 am and sets at 7:22 pm, giving 12 hours 2 minutes of daylight. Solar noon, the moment the sun is highest, falls at 1:21 pm, which is 81 minutes after clock noon.

That gap is the whole argument about where zone lines belong, in one number. It is made of three things: Havana, Cuba sitting 22.4 degrees west of the UTC-4 meridian, the equation of time, which today runs 8.7 minutes ahead of mean time, and the hour of daylight saving currently in force. Full sunrise and sunset times for Havana.

Convert America/Havana to another time zone

The converter is keyed on the abbreviations people type rather than on identifiers. America/Havana is at UTC-4 right now, the same reading as EST, 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.

Because the offset is an output and the identifier is the input. This zone alone has two offsets in a year, and 47 other zones share its current reading while carrying different rules.
