HST to PST Converter

Convert Between HST and PST

If you’ve ever had to juggle meetings between Hawaii and the U.S. West Coast, you know it’s easy to get tripped up by time differences—especially when daylight saving time enters the mix. This tool takes the confusion out of it. Whether you're in Honolulu or San Francisco, this HST–PST time converter makes it simple to figure out exactly what time it is in either zone.

Why Use a Time Converter Like This?

Let’s say you're planning a virtual meeting, catching a flight, or trying to catch someone at their desk hours away. You could Google the time difference and do the mental math. Or you could plug the time into this converter and know instantly whether you're early, late, or right on schedule. It’s especially handy when Pacific Time switches between standard and daylight saving, while Hawaii doesn’t change at all.

How It Works

Pick Your Starting Time

At the top, you’ll see two input fields - one for the date, one for the time. These default to your current local HST time, but you can change them to anything you like. Just below, choose whether the time you’re entering is in Hawaii or Pacific Time.

Choose How the Tool Behaves

In the "Conversion Settings" section, you’ve got three checkboxes that let you fine-tune how the tool handles time:

• Auto Convert: When this is on, the calculator runs the moment you change a date or time—no need to click a button.
• Daylight Saving Aware: Keeps the math accurate even when Pacific Time shifts to daylight time.
• Show UTC Offset: Adds detail for folks who like to see raw UTC offsets like "-10:00" or "-07:00".

Convert, Swap, Reset

Below the settings, there’s a row of buttons:

• Convert: Runs the conversion based on your current selections.
• Swap: Flips your input and output timezones - useful if you're going the other direction.
• Now: Sets the input to the current time in your selected zone.
• Reset: Clears everything out and resets the interface.

Helpful Details in the Output

The result area gives you more than just a converted time. You’ll also see:

• The converted time and date, clearly formatted
• Time difference in hours
• UTC offsets for both zones
• Daylight saving status (PST or PDT)
• Formatted displays of both input and output times for easy reference

Live Clock and Format Switching

Want to see what time it is *right now* in both Hawaii and the Pacific zone? You’ll find live clocks at the bottom of the page that update every second. You can even switch between 12-hour and 24-hour formats with a click if you prefer military time or just want to skip the AM/PM.

Answers to Common Head-Scratchers

Does it know when daylight saving time starts or ends?

Yes. The tool checks each date you enter to determine whether Pacific Time is on standard or daylight time and adjusts accordingly.

What happens if I enter a time in PST instead of HST?

Just use the dropdown to switch the input zone from HST to PST. The display updates so you always know which direction the conversion is going.

Can I use keyboard shortcuts?

You can. Press space to convert, “S” to swap zones, “N” for now, “R” to reset, and “F” to toggle time formats - no mouse needed.

Why does Hawaii stay the same all year?

Hawaii doesn’t observe daylight saving time. It stays locked at UTC-10 year-round, which makes things simpler from that end.

Stay On Time, Every Time

Whether you're scheduling a team call, planning a visit, or just double-checking when to send that email, this converter helps you keep your timing right. No more second-guessing or fiddling with calendar settings. Just clear, instant answers tailored for two zones that don’t always play by the same rules.
