What CDT and AKST Actually Are
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.
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.
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.
