CST to AKST — Central to Alaska Time

Alaska Time is 3 hours behind Central Time, summer and winter both.

The conversion rule

Subtract 3 hours from Central Time to get Alaska Time. 12:00 PM CST is 9:00 AM AKST. Anchorage follows the same DST calendar as the Lower 48, so the 3-hour offset is constant.

12:00–5:00 PM CT / 9:00 AM–2:00 PM AKT is the shared block — five hours. Hold Anchorage calls after the Central lunch hour rather than before it.
