ET to HST Conversion Guide

What is ET to HST Conversion?

ET to HST conversion helps you translate time between Eastern Time and Hawaii Standard Time. Eastern Time switches between EDT (UTC-4) during daylight saving time (March-November) and EST (UTC-5) during standard time (November-March). HST is always UTC-10 throughout the year with no daylight saving changes. HST is consistently 6 hours behind EDT and 5 hours behind EST, making it one of the largest time differences within the United States.

Time Zone Information

Eastern Daylight Time (EDT): UTC-4, used in eastern United States during daylight saving time from second Sunday in March to first Sunday in November.

Eastern Standard Time (EST): UTC-5, used during standard time from first Sunday in November to second Sunday in March.

Hawaii Standard Time (HST): UTC-10, used year-round in Hawaii with no daylight saving time adjustments.

Time Difference: HST is 6 hours behind EDT and 5 hours behind EST.

Daylight Saving Time Impact

Eastern Time Changes: EDT observed from second Sunday in March to first Sunday in November

Hawaii Consistency: HST never changes and remains UTC-10 throughout the year

Variable Difference: Time difference changes between 5-6 hours depending on whether Eastern Time observes DST

Hawaii Advantage: No confusion with time changes - HST stays constant year-round

Common Conversion Examples

Business Hours (EDT to HST)

Winter time conversion (November-March)

International Meetings

EST 3:00 PM → HST 10:00 AM

Best overlap for mainland-Hawaii business

Late Night Calls

EDT 11:00 PM → HST 5:00 PM

EST 11:00 PM → HST 6:00 PM

Eastern evening reaches Hawaii afternoon

Conversion Tips & Best Practices

• Hawaii never observes daylight saving time - HST stays constant at UTC-10

• Eastern Time switches between EDT (UTC-4) and EST (UTC-5) twice yearly

• Subtract 6 hours from EDT or 5 hours from EST to get HST

• Best meeting times: EDT/EST 2-6 PM for HST business hours (8 AM-12 PM)

• Hawaii is the only US state that doesn't observe daylight saving time (except Arizona)

• HST covers all Hawaiian islands and some US territories in the Pacific

ET to HST Converter

If you're trying to keep meetings aligned across Eastern Time and Hawaii Standard Time, this converter takes care of the math. Whether you're on a team split between the mainland and the islands, or simply planning a call with family in Hawaii, the tool helps bridge the 5 to 6-hour difference with ease. Here's a quick snapshot of how the two time zones line up, and which countries fall into each:

Eastern Time (ET) UTC−4 / UTC−5	Hawaii Standard Time (HST) UTC−10
🇺🇸 United States (East Coast) 🇨🇦 Canada (Ontario, Quebec, etc.) 🇧🇸 Bahamas 🇨🇺 Cuba 🇭🇹 Haiti 🇯🇲 Jamaica 🇸🇻 El Salvador 🇧🇿 Belize 🇹🇨 Turks and Caicos 🇰🇾 Cayman Islands	🇺🇸 United States (Hawaii) 🇫🇲 Micronesia (Western Islands) 🇲🇭 Marshall Islands (Kwajalein) 🇵🇼 Palau 🇰🇮 Kiribati (Phoenix Islands) 🇬🇺 Guam (unofficially uses Chamorro Standard Time, same as HST) 🇺🇸 American Samoa (technically UTC−11, but sometimes referenced near HST)

What this time converter actually does

This tool translates any time you pick between Eastern Time and Hawaii Standard Time, both ways. It accounts for daylight saving changes in Eastern Time and keeps Hawaii’s constant UTC−10 offset in mind. You can go from 3 PM in New York to what that looks like in Honolulu, or the other way around. It works whether you're scheduling a call, checking time differences before traveling, or just curious about how far ahead or behind one coast is from the other.

Why this matters more than you think

Eastern Time and Hawaii Standard Time are six or five hours apart depending on the season. That's a big enough gap to cause mix-ups, especially for remote teams, service appointments, or event planning. This converter keeps that from becoming your problem. It makes sure you hit the right window, whether you're working across departments or calling family during lunch break.

How to use it without second guessing yourself

Step 1: Set your base time

Pick a date and time on the left side. By default, the input zone is Eastern Time, but you can switch it using the dropdown to convert from Hawaii instead.

Step 2: Review or adjust conversion settings

Auto Convert: Converts automatically when you change the time or date.
Daylight Saving Aware: Adjusts for daylight time in Eastern zones when active (March to November).
Show UTC Offset: Adds the UTC difference for both zones.
Show Seconds: Includes seconds in the time display if you need that level of detail.

Step 3: Convert and view results

Click “Convert Time” or rely on auto convert if it’s turned on. The output area shows both the formatted converted time and additional details like UTC offset, current daylight saving status, and the exact difference in hours.

Step 4: Use quick controls

Swap: Flips the input and output zones.
Now: Sets the current time automatically based on the selected zone.
Reset: Returns everything to the default state (Eastern Time, current date and time).
Format Toggle: Switches between 12-hour and 24-hour formats.

What the settings really mean

If you’ve ever wondered “Is it EDT or EST right now?”, this tool figures it out for you. When Daylight Saving is checked, the tool automatically shifts between UTC−4 (EDT) and UTC−5 (EST) based on your selected date. Hawaii doesn’t change at all, so you’ll always see UTC−10 there.

The DST switch is built into the logic. For example, if you choose March 10 or November 5, the tool will automatically calculate which side of the daylight shift you're on. No guessing required.

A real-world example of when this saves your neck

Imagine you’re part of a team with members in Washington DC and Honolulu. You’ve got a recurring sync every Monday at 2:00 PM Eastern Time. Without a converter, one wrong assumption during DST season can lead to someone showing up an hour late (or early). Using this tool, you’d instantly see that 2:00 PM EDT lines up to 8:00 AM HST in summer. When DST ends, that same 2:00 PM becomes 9:00 AM in Hawaii. No mental math needed.

Little touches that make things easier

The tool live-updates both Eastern and Hawaiian clocks every second
It reacts to your keyboard: press space or enter to convert, "N" to jump to now, "S" to swap zones
If something looks off, just hit Reset and start fresh

Get the timing right between the coast and the islands

Whether you're planning a meeting, checking flight times, or just trying to avoid a wake-up call at 3 AM, this converter makes sure you stay on track. The difference between New York and Honolulu is big, but the mistake doesn't have to be. This tool keeps you in sync, even when time itself isn’t.
