AKST – Alaska Standard Time
UTC-09:00Alaska Standard Time (AKST) is the time zone for the state of Alaska, 9 hours behind UTC.

- •Anchorage is the most populous city in AKST with about 290,000 people.
- •The Aleutian Islands use HAST instead of AKST.
CDT – Central Daylight Time
UTC-05:00Central Daylight Time (CDT) is the daylight saving offset in the Central Time Zone, 5 hours behind UTC.
- •CDT is the same offset as EST (UTC-05:00), which can cause confusion.
- •CDT runs from the second Sunday in March to the first Sunday in November.
Understanding the +4h Gap: AKST vs CDT
AKST runs on Alaska Standard Time (AKST) at UTC-09:00. CDT runs on Central Daylight Time (CDT) at UTC-05:00. That puts AKST 4 hours ahead of CDT — a difference of +4h at the current offsets.

Why people convert AKST to CDT time
- Scheduling a call from AKST to CDT: a 10:00 AM start in AKST lands at 2:00 PM in CDT, so you can confirm the slot without doing the arithmetic yourself.
- Finding shared working hours: both AKST and CDT are inside the 9-to-5 working day between 9:00 AM and 1:00 PM AKST time (1:00 PM–5:00 PM CDT). That is roughly 4 hours of usable overlap.
- Keeping family and friends in sync: knowing that 8:00 PM in AKST is 12:00 AM in CDT makes it easy to avoid calling at 3 AM.
- Always state the zone abbreviation, not just the hour. "3:00 PM AKST" is unambiguous; "3 PM" across a +4h gap is not.
- Block 9:00 AM–1:00 PM AKST as the recurring meeting window if you work primarily from AKST and need CDT colleagues present.
About AKST (Alaska Standard Time)
Alaska Standard Time (AKST) is used in nearly all of Alaska. Due to Alaska's vast geographic size, the Aleutian Islands use Hawaii-Aleutian Standard Time instead. During summer months, Alaska switches to Alaska Daylight Time (AKDT, UTC-08:00).
About CDT (Central Daylight Time)
Central Daylight Time (CDT) is observed during summer months in the US and Canadian portions of the Central Time Zone. Clocks are moved forward by one hour, aligning with Eastern Standard Time (EST). Most of Mexico and Central America do not observe CDT, staying on CST year-round.
Best time to call between AKST and CDT
Both AKST and CDT sit inside the 9 AM – 5 PM working day between 9:00 AM–1:00 PM AKST, which is 1:00 PM–5:00 PM CDT. That gives roughly 4 hours of shared time — the safest window for a live call or meeting.
Business hours overlap
AKST and CDT overlap for about 4 hours during the working day — enough for meetings if you avoid the edges of the window.
AKST is 4 hours ahead of CDT (AKST UTC-09:00 → CDT UTC-05:00). The shared working window is 9:00 AM–1:00 PM AKST. Remember to re-check around daylight-saving transitions.
