Which zone this page means. South Korea does not observe daylight saving, so KST applies all year. It shares an offset with Japan. PST is standard time only. From the second Sunday in March to the first Sunday in November the Pacific zone is on PDT (UTC-7). Most people write PST year-round.

KST is ahead of PST by 16 hours today

On 19 August 2026, Korea Standard Time is on KST at UTC+09:00 and Pacific Standard Time is on PDT at UTC-07:00. The gap between them is 16 hours, with PST behind. So 9:00 am in KST is 5:00 pm in PST, and 5:00 pm in KST is 1:00 am in PST. Going the other way, see PST to KST.

The gap is not constant, and that is the part that catches people out

Pacific Standard Time is currently observing daylight saving and changes next on 1 November 2026. Korea Standard Time does not observe daylight saving, so the gap moves only when Pacific Standard Time changes its clocks — twice a year, by one hour.

When you can actually both be at work

Taking a working day as 9:00 am to 5:00 pm local at each end, there are 0 overlapping hours in a normal day. There is none: the two working days do not touch at all, so any live meeting between Korea Standard Time and Pacific Standard Time has to sit outside somebody's normal hours. The table above shows which end has the shorter stretch to give up.

Zone rules are set by legislation and change, sometimes at short notice. This page is built against tzdata 2026a, last reviewed 2026-08-18. Quarterly. Zone rules change by legislation, sometimes at short notice. Version and review date are shown on every zone page. The converter above reads your browser's own copy of the zone database, so if a rule has changed since this page was built the live answer follows the new rule.

Every convention used above — whether the start date counts, how month ends are clamped, which holidays close an office — is written out on the methodology page, including the daylight-saving rules behind the 16-hour gap above.

Common questions

What is the time difference between KST and PST?
The current offset is shown at the top of this page. It is computed for today's date rather than quoted as an average, because the two regions change their clocks on different dates and the gap is different for a few weeks each year.
Is KST the same as Korea Standard Time all year?
Not necessarily. Standard time and summer time are separate zones with separate abbreviations, so much of the year the technically correct abbreviation is the daylight one. The page states which is in force on today's date.
When do the clocks change in these zones?
The next change date for each zone is shown in the result panel, along with what the offset becomes afterwards.
What is a good meeting time between KST and PST?
The business-hours overlap window is shown below the converter. Where there is no overlap the page says so rather than suggesting an impossible time.
