What AKST and CDT Actually Are
AKST — Alaska Standard Time
Anchorage, Fairbanks, Juneau. Standing at UTC-9:00 as written, and the region does change its clocks, so its live offset moves by an hour twice a year. The next change is on Sunday, November 1, 2026, to AKST.
Alaska compressed four time zones into one in 1983, moving most of the state onto a single clock to keep business hours aligned with the rest of the country.
CDT — Central Daylight Time
Chicago, Houston, Dallas, Winnipeg. Standing at UTC-5:00 as written, and the region does change its clocks, so its live offset moves by an hour twice a year. The next change is on Sunday, November 1, 2026, to CST. Mexico abolished daylight saving in 2022, so Mexico City stays on UTC-6 all year and no longer uses CDT.
Mexico left this pattern behind in 2022, abolishing daylight saving nationwide except in a strip of cities along the US border that kept it for cross-frontier trade.
What This Means in Practice
Both sides change clocks, on different dates
Both regions observe daylight saving but do not switch on the same day, so for a week or two each spring and fall the gap between them is an hour different from the rest of the year. Those short windows are where recurring invitations quietly break.
