PST to KST Conversion Guide

What is PST to KST Conversion?

PST to KST conversion helps you translate time between Pacific Standard Time and Korea Standard Time zones. PST is UTC-8 during standard time and UTC-7 during daylight saving time (PDT). KST is always UTC+9 and never changes for daylight saving time. The time difference varies between 16-17 hours depending on whether PST observes daylight saving time, with KST being ahead.

Time Zone Information

Pacific Standard Time (PST): Used on the US West Coast including California, Oregon, Washington, and parts of Canada. UTC-8 during standard time, UTC-7 during daylight saving time (PDT).

Korea Standard Time (KST): Used throughout South Korea and North Korea. Always UTC+9 with no daylight saving time adjustments ever implemented.

Time Difference: KST is 17 hours ahead of PST during standard time and 16 hours ahead during PDT (daylight saving time).

Daylight Saving Time Impact

PST observes DST: From second Sunday in March to first Sunday in November, PST becomes PDT (UTC-7)

KST never changes: Korea Standard Time remains UTC+9 throughout the year with no daylight saving adjustments

Variable difference: Time difference changes from 17 hours (PST season) to 16 hours (PDT season)

Conversion Tips & Best Practices

• KST is almost a full day ahead of PST - remember to account for date changes

• Korea never observes daylight saving time, making KST completely predictable

• Best meeting times: PST evening (5-9 PM) converts to KST morning (9 AM-1 PM next day)

• Time difference changes twice yearly when PST switches to/from PDT

• Korea's business hours are typically 9 AM to 6 PM KST

• Consider that KST spans the International Date Line relative to PST

Pick a Date, Set the Time, and Watch the Conversion Happen

This converter lets you pick any date and time in either PST or KST, and it instantly shows you the equivalent in the other timezone. It's not just about the hour, it handles the date switch, daylight saving, and even lets you flip formats or adjust for seconds. All this from a clean, user-friendly panel that stays out of your way while doing the math for you.

Why This Tool Comes in Handy

Think about someone working remotely from Seoul while collaborating with a tech team in San Francisco. Meetings, launch events, deadline reminders, they all need tight timing. This converter helps you avoid misfires by accounting for every twist in the time difference, even that sneaky daylight saving switch in the U.S.

Here’s How to Use It Without Overthinking

Start With a Time

Pick the date and time in the top section. By default, it assumes you’re starting with Pacific Standard Time, but you can swap that with the “⇄ Swap” button anytime.

Choose Your Timezone

There’s a dropdown right next to the time field. You can flip between PST and KST, depending on where you're starting from. Once selected, the output zone updates automatically.

Click Convert or Let It Auto-Run

Auto-convert is turned on by default, which means the conversion updates the moment you change the time or date. Prefer to press the button? Turn off auto-convert and use the "Convert Time" button when you’re ready.

Extra Settings If You Want More Control

Daylight Saving Aware: Keeps track of whether it's standard or daylight time in the U.S.
Show UTC Offset: Displays how far each zone is from UTC at that moment.
Show Seconds: Adds seconds to the result, helpful if you’re working with servers or schedules down to the second.
12/24 Hour Format Toggle: Choose the time format that makes sense to you.

Real Example: When California Talks to Seoul

Imagine a tech company in San Jose setting up a video call with a partner firm in South Korea. If the California team schedules a meeting at 5:00 PM PST on a Monday, this tool will show that it’s 10:00 AM on Tuesday in KST (during daylight time). It saves back-and-forth emails and gives both teams confidence in their calendars.

Smart Features That Run Quietly in the Background

The converter doesn’t just switch hours. It checks for daylight saving time based on U.S. rules, adjusts the UTC offset if needed, and updates labels to reflect whether you’re working in PST or PDT. There’s also a live clock showing the current time in both zones, which refreshes every second. Want to reset everything? Hit the "Reset" button and you're back to the current PST time.

What If You Start in Korea?

You can easily switch the input zone to KST using the dropdown or the “⇄ Swap” button. Once you do, the left panel updates to Korean time, and the right side will show you the corresponding Pacific time, whether it’s standard or daylight. The rest of the tool keeps working the same way.

Keep Pacific-Korea Scheduling Smooth With One Click

Whether you're tracking meetings, webinars, flights, or delivery deadlines across Los Angeles and Seoul, this converter has you covered. It's practical, snappy, and accurate down to the second. Let it handle the time math while you focus on getting things done.
