HST to AKST Conversion Guide

What is HST to AKST Conversion?

HST to AKST conversion helps you translate time between Hawaii Standard Time and Alaska Standard Time zones. HST is always UTC-10 and never changes for daylight saving time. AKST is UTC-9 during winter but becomes AKDT (UTC-8) during summer daylight saving time. The time difference varies from 1 hour (HST to AKST) to 2 hours (HST to AKDT) depending on the season.

Time Zone Information

Hawaii Standard Time (HST): Used throughout Hawaii including Honolulu, Pearl City, and Hilo. Always UTC-10 with no daylight saving time adjustments ever implemented.

Alaska Standard Time (AKST): Used in most of Alaska including Anchorage, Fairbanks, and Juneau. UTC-9 during standard time, UTC-8 during daylight time (AKDT).

Time Difference: AKST is 1 hour ahead of HST during winter. AKDT is 2 hours ahead of HST during summer daylight saving period.

Daylight Saving Time Impact

Hawaii: Never observes daylight saving time - HST remains UTC-10 throughout the year

Alaska: Observes daylight saving time from second Sunday in March to first Sunday in November, becoming AKDT (UTC-8)

Variable Difference: The time difference changes seasonally: 1 hour during AKST period, 2 hours during AKDT period

Convert Between Hawaii and Alaska Time

If you're juggling schedules between Hawaii and Alaska, you already know it can be a little tricky. One never shifts for daylight saving time. The other does, but only part of the year. That’s where this time converter comes in, it’s built specifically for the Hawaii Standard Time (HST) and Alaska Standard Time (AKST) zones. Whether you’re planning a call, booking a flight, or just keeping in sync with friends or colleagues, this tool clears up the confusion fast.

What the time converter does for you

This tool makes it simple to see what time it is in Alaska when it's a certain time in Hawaii, and vice versa. It handles the details you shouldn't have to think about, like daylight saving changes in Alaska, or whether you're working in 12-hour or 24-hour format. Just enter a date and time in either zone and get an instant, accurate conversion to the other side.

Where it helps most

Say you're in Hilo, Hawaii and you're planning a project meeting with a client based in Fairbanks, Alaska. During winter, you're just one hour apart. But in the summer months, the time gap grows to two hours. This converter tells you the correct difference, based on the date you choose, without needing to look up anything manually.

How to use it, step by step

1. Pick a date and time

Start by selecting a date and a time in the left-hand box labeled either “Hawaii Standard Time (HST)” or “Alaska Standard Time (AKST),” depending on your chosen input zone. Use the dropdown to switch between them if needed.

2. Let it convert automatically or press a button

By default, the “Auto Convert” box is checked. That means the tool updates as soon as you change the date or time. If you prefer, uncheck that box and use the “Convert Time” button whenever you're ready.

3. View your result

The right-hand panel shows you the converted time and date. It also includes bonus details like:

The exact time difference between zones

Whether Alaska is currently observing daylight time

4. Toggle options to match your needs

You can change the clock to show either 12-hour or 24-hour format with one click. There's also an option to include seconds, which updates live if you're curious about the exact current time in both places.

Extra features to make things easier

Swap timezones instantly

Use the “Swap” button to flip the input and output zones. It automatically updates labels and recalculates for you, so you don’t need to re-enter anything manually.

Jump to the current time

Tap the “Now” button to instantly fill in the current time for your selected input zone. Great if you’re scheduling something that starts right away or within the hour.

Start over clean

The “Reset” button clears your selections and puts everything back to the current Hawaii time by default. It’s handy if you’ve been experimenting with different dates and want to start fresh.

Helpful things to know while using it

Alaska uses daylight saving time from March to November, moving from AKST (UTC-9) to AKDT (UTC-8). The converter tracks this automatically.
Hawaii never changes. It stays fixed at UTC-10, all year long.
Offset displays are optional. You can check a box to show them in either whole-number or “:00” format.
Keyboard shortcuts are built in. Press “Enter” to convert, “S” to swap zones, “N” for now, “R” to reset, and “F” to flip time format.

One tool to keep your Hawaii-Alaska plans running smoothly

You don’t need to memorize which day daylight saving time starts or ends. This calculator handles it. Whether you're planning a 10 AM conference call from Honolulu to Juneau or scheduling travel between Pearl City and Anchorage, you’ll have the right time in front of you without guesswork. It's designed to be fast, accurate, and easy to use anytime you need it.
