When the difference changes
Argentina Time and Alaska 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:
- Now – November 1, 2026Alaska Time is 5 hours behind
- November 1, 2026 – March 14, 2027Alaska Time is 6 hours behind
- March 14, 2027 – onwardsAlaska Time is 5 hours behind
Periods shorter than a day are not listed: both zones change at 2am in their own local time, so there are a few hours on each transition date when the gap is briefly something else.
Daylight saving
Argentina Time
Argentina Time stays on ART all year, so its offset from UTC never moves.
Alaska Time
Clocks go back one hour at 2am local time, becoming AKST.
