It is 10:16 am in America/Indiana/Marengo

America/Indiana/Marengo is the IANA identifier for the time zone of Marengo in the United States. It is running at UTC-4 right now, abbreviated EDT, 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/Indiana/Marengo right now

10:16 am on Saturday, September 26, 2026, as this page was served, which in 24 hour form is 10:16. 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/Indiana/Marengo throws away the rule that decides what they all do at the next transition.

The UTC offset of America/Indiana/Marengo

An offset of UTC-4 names the meridian 60.0 degrees west. Washington, United States actually sits at 77.04 degrees west, which is 17.0 degrees west of it, so the sun there runs about 68 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/Indiana/Marengo

America/Indiana/Marengo does observe daylight saving. The next change is on November 1, 2026: at 1:00 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/Indiana/Marengo 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 5 distinct eras in that time and has used 2 different offsets: UTC-5, UTC-4. Its current behaviour has held since 2006. 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.

Countries and regions that use America/Indiana/Marengo

One country uses America/Indiana/Marengo: the United States, which keeps 29 zones in total and has a population of about 334,910,000.

Cities in the America/Indiana/Marengo time zone

This site does not yet carry a city page inside America/Indiana/Marengo, so the readings here are computed for the identifier itself and anchored at Washington, United States. 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 America/Indiana/Marengo

Worked out for Washington, United States, the capital of a country that keeps the zone, at 38.91 degrees north, 77.04 degrees west. The sun rises at 7:00 am and sets at 6:59 pm, giving 11 hours 59 minutes of daylight. Solar noon, the moment the sun is highest, falls at 12:59 pm, which is 59 minutes after clock noon.

That gap is the whole argument about where zone lines belong, in one number. It is made of three things: Washington, United States sitting 17.0 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.

Convert America/Indiana/Marengo to another time zone

The converter is keyed on the abbreviations people type rather than on identifiers. America/Indiana/Marengo 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.
