Timezones

The timezone ART in Argentina

Timezones are always computed by their difference to UTC, the "Universal Time Coordinated". In Argentina exists only a single tonezone at UTC-3. E.g. New York is currently at UTC-4 in Eastern Time, so the time difference between NY and Argentina is 1 hours.

Argentina has no time difference between summer and winter. A daylight saving time doesn't exist.

Argentina has an east-west extension of 18.7 degrees of longitude. Given the country's location in South America, this corresponds to about 1600 kilometers. At this extension, the sun's course is noticeable at different positions in the country, but it still turns out to be moderate. The position of the sun in the west of the country differs from that in the east by about 75 minutes. This means the sun rises and sets 75 minutes later in the west than in the east.

No more daylight saving time in Argentina

Due to the sun's orbit around the equator, the days are longer in summer (November to February in the southern hemisphere). Countries that switch to daylight saving time in the summer months align the daylight phase with the human rhythm. Unused bright morning hours are thus shifted into the evening (more information on daylight saving time here).

Due to its distance from the equator, the impact would be significant in Argentina. Buenos Aires is located 3,900 km from the equator. A day in midsummer would then not last from 05:36 to 20:07, but from 06:36 to 21:07. Nevertheless, in 2009 it was decided to finally abandon daylight saving time in Argentina.
