What time is it in America/Argentina/Mendoza right now

11:17 am on Saturday, September 26, 2026, as this page was served, which in 24 hour form is 11:17. 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 America/Argentina/Mendoza throws away the rule that decides what they all do at the next transition.

The UTC offset of America/Argentina/Mendoza

An offset of UTC-3 names the meridian 45.0 degrees west. Mendoza, Argentina actually sits at 68.85 degrees west, which is 23.8 degrees west of it, so the sun there runs about 95 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 never moves its clocks, UTC-3 is the answer on every day of the year. That makes it an easy zone to schedule against, with the caveat that the other end of the call may still be moving its own clocks, so the gap between the two changes even though nothing changed here.

Daylight saving in America/Argentina/Mendoza

America/Argentina/Mendoza does not observe daylight saving. It sits at UTC-3 in January and reads UTC-3 again in July, so a gap worked out against it today is still right in six months. It did move them once: the sampling below shows a summer offset as late as 2008, and the practice has since been dropped.

The database holds no clock change for America/Argentina/Mendoza in 2025, 2026 or 2027, so there is no transition table to print. The offset shown at the top of this page is the offset on every date in those three years.

How the offset of America/Argentina/Mendoza 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 10 distinct eras in that time and has used 3 different offsets: UTC-4, UTC-3, UTC-2. Its current behaviour has held since 2009. 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 last summer in which America/Argentina/Mendoza read a different offset from its own January was 2008. Software that still carries a hand-written summer rule for this zone has been wrong every year since.

Cities in the America/Argentina/Mendoza time zone

The 3 cities this site covers inside America/Argentina/Mendoza, 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/Argentina/Mendoza

Worked out for Mendoza, Argentina, the city this site covers inside the zone, at 32.89 degrees south, 68.85 degrees west. The sun rises at 7:19 am and sets at 7:35 pm, giving 12 hours 15 minutes of daylight. Solar noon, the moment the sun is highest, falls at 1:27 pm, which is 87 minutes after clock noon.

That gap is the whole argument about where zone lines belong, in one number. It is made of three things: Mendoza, Argentina sitting 23.8 degrees west of the UTC-3 meridian, the equation of time, which today runs 8.7 minutes ahead of mean time, and no daylight saving at all, because this zone does not use it. Full sunrise and sunset times for Mendoza.

Convert America/Argentina/Mendoza to another time zone

They will diverge if the two zones ever adopt different daylight saving rules, which is exactly why the identifier is the thing worth storing.
