When the difference changes

Atlantic Time and Argentina Time do not change their clocks on the same dates, so the gap between them is not the same all year. Most converters show only today’s figure. These are the periods ahead:

  1. Now – March 14, 2027Argentina Time is 1 hour ahead
  2. March 14, 2027 – November 7, 2027Argentina Time is the same time
  3. November 7, 2027 – onwardsArgentina Time is 1 hour ahead

Periods shorter than a day are not listed. Each zone changes at its own local time, so on a date when both move there are a few hours when the gap is briefly something else.

Clocks go forward one hour — 2:00 am becomes 3:00 am local time, and the zone is on ADT after that.

Scheduling between the two

Working hours overlap from 9:00 am to 5:00 pm AST, which is 10:00 am to 6:00 pm ART. Anything inside that window falls in the normal working day at both ends.

A note on AST: it can also mean Arabia Standard Time (UTC+3). This page means Atlantic Time.

Atlantic Time (AST) is used in Nova Scotia, New Brunswick and Puerto Rico
