Hi, back here after 12+ years for a heads up...
There is a Law proposal approved by the Cámara de Diputados (equivalent of the House) but yet to be approved in the Senate regarding Argentina's timezone.
Argentina is currently in UTC-3 with no DST. The proposal establishes the Official Time for the whole country as UTC-4 (which is geographically more accurate), with a DST of UTC-3.
The DST would start at 00:00 on the first April Sunday and would end at 00:00 on the first September Sunday.
The Executive is authorized to modify these dates and to coordinate with other countries of MERCOSUR to apply changes on the same moment.
This is just a heads up, since the Senate did not approve or modify the proposal.
If this is approved and enacted before April 2026, we can assume the current status is DST and at 00:00 Sunday April 5th 2026 we would be moving the clock back to 23:00 Saturday April 4th.
I'll keep you posted as this evolves, but don't hold your breath since on October 26th there are Legislative Elections (midterm), and half of the House and one third of the Senate will change. The new legislators will take office on December 10th. By the end of December the ordinary session of Congress ends; it may be extended by the Executive Branch, but there is no certainty about which bills can be discussed.
