Why people convert Los Angeles to Seoul time
- Scheduling a call from Los Angeles to Seoul: a 10:00 AM start in Los Angeles lands at 2:00 AM in Seoul the next day, so you can confirm the slot without doing the arithmetic yourself.
- Handling a +16h gap: Los Angeles and Seoul have no overlap inside a normal 9-to-5 day, so real-time meetings need an early-morning or late-evening slot on one side. 9:00 AM in Seoul is 1:00 AM in Los Angeles.
- Coordinating a Los Angeles-based team with Seoul contacts: quoting times in the other side's local clock — not your own — removes the single biggest source of missed meetings.
- Always state the zone abbreviation, not just the hour. "3:00 PM PDT" is unambiguous; "3 PM" across a +16h gap is not.
- With a +16h gap there is no shared 9-to-5 window, so alternate the early start: one week Los Angeles takes the early slot, the next week Seoul does.
