Exceptions & Nuances

• Aleutian Islands (west of 169°30'W): Use Hawaii-Aleutian Time (HST/HDT) — 4 hours behind LA in summer, 3 in winter.
• Louisiana never changes zones — whole state is Central.
• Alaska is one zone (mostly) — 90% of population in AKST/AKDT.

Scheduling Tip

When setting meetings: "10 AM AKST / 1 PM CST" — always specify both. Tools like timeanddate.com handle DST automatically.

Three hours. Every day. Simple as that.
