KST to PT Conversion Guide

What is KST to PT Conversion?

KST to PT conversion helps you translate time between Korea Standard Time and Pacific Time. KST is always UTC+9 and never changes throughout the year. PT switches between PST (UTC-8) in winter and PDT (UTC-7) in summer. The time difference varies between 16-17 hours depending on whether Pacific Time observes daylight saving time, with KST always being ahead (next day in most cases).

Time Zone Information

Korea Standard Time (KST): Used in South Korea and remains constant at UTC+9 throughout the year. Does not observe daylight saving time.

Pacific Time (PT): Used in western United States and Canada. UTC-8 during standard time (November-March), UTC-7 during daylight time (March-November).

Time Difference: KST is 17 hours ahead of PST (winter) or 16 hours ahead of PDT (summer).

Daylight Saving Time Impact

KST Consistency: Korea Standard Time never changes and remains UTC+9 year-round

PST Period: Standard time from first Sunday in November to second Sunday in March (UTC-8)

PDT Period: Daylight time from second Sunday in March to first Sunday in November (UTC-7)

Conversion Tips & Best Practices

• KST never changes - it's always UTC+9 throughout the year

• PT switches between PST and PDT, changing the time difference from 17 to 16 hours

• Most KST times convert to the previous day in Pacific Time

• Best meeting times: KST evening (10-11 PM) = PT morning (6-7 AM or 7-8 AM)

• Korean business hours (9 AM - 6 PM KST) overlap with PT late evening/early morning

• Always verify whether PST or PDT is in effect when scheduling across seasons

Why anyone juggling KST and PT should bookmark this

If you work across continents or frequently talk to people based in Korea or on the US WEST Coast, this tool saves you from mental math and calendar slip-ups. With daylight saving changes in PT and none in KST, it’s surprisingly easy to misjudge the time by an hour or even a full day. This converter not only prevents mistakes, it lets you plan better. It’s perfect for freelancers, remote teams, gamers, event organizers, and digital nomads alike.

How to use the converter without breaking a sweat

Pick your time and zone

Start by selecting a date and time using the input fields. By default, the calculator assumes you’re entering a KST time. But you can easily flip it by choosing “PT” in the dropdown. This tells the converter whether to treat your entry as Korea or Pacific time.

Press a button or let it auto-convert

If you have “Auto Convert” turned on, it’ll update results the moment you adjust anything. Otherwise, you can hit the “Convert Time” button when you're ready. You’ll get the converted time in the other timezone, along with the date (which sometimes shifts due to the time difference).

Swap direction

The “Swap” button flips which zone you’re inputting from. So if you started with KST but want to see what 3 PM PT looks like in Korea, just click that button and go.

Use “Now” to fill the input fields with the current time in the selected zone. Perfect for finding the present equivalent across timezones instantly.

Reset for a clean start

The “Reset” button clears all your entries and resets the interface to its default state. No need to refresh your browser.

Keep these things in mind as you use it

If you're entering a Pacific Time during the summer, the tool knows to treat it as PDT (UTC-7), not PST (UTC-8)
KST never uses daylight saving time, so it’s a rock-solid reference point
Time difference changes: 16 hours apart during PDT, 17 hours apart during PST
Most of the time, KST will land on the next calendar day compared to PT

Let’s say you’re scheduling across Seoul and Vancouver

You’ve got a call set for Tuesday at 10 AM in Seoul. With this tool, you find out that lands on Monday 6 PM in Vancouver during daylight saving months. Without it, you might’ve shown up 17 hours late or early. That’s a big miss. This is the kind of quick, real-life scenario this converter is perfect for—reliable planning without second-guessing.
