Frequently Asked Questions
What is the time difference between PST and KST?
During standard time, Korea Standard Time is 17 hours ahead of Pacific Standard Time.
What is the difference between PST and PDT?
PST (Pacific Standard Time) is the winter offset at UTC-8, observed from the first Sunday in November through the second Sunday in March. PDT (Pacific Daylight Time) is the summer offset at UTC-7, active when Daylight Saving Time shifts clocks forward by one hour.
Which major cities observe Pacific Standard Time?
Major cities that observe Pacific Standard Time include Los Angeles, San Francisco, Seattle, Las Vegas, Vancouver, and Tijuana.
Does South Korea observe Daylight Saving Time?
South Korea does not observe Daylight Saving Time and has not done so since 1988, when DST was discontinued following the Seoul Summer Olympics. KST remains fixed at UTC+9:00 every day of the year, meaning the offset between Seoul and any DST-observing country shifts by one hour twice annually when those countries change their clocks.
Are KST and JST the same?
Yes, Korea Standard Time (KST) and Japan Standard Time (JST) share the identical UTC+9:00 offset, and neither country observes Daylight Saving Time. Seoul and Tokyo run on exactly the same clock year-round, which directly supports the deep semiconductor, automotive, and consumer electronics supply chain integration between the two economies.
