How the gap works

The gap is not constant. Because Los Angeles changes its clocks for daylight saving time and Seoul does not, the difference becomes 17 hours for part of the year. The live section above shows the exact gap right now and when it next changes.

  • Los Angeles (United States) is in the America/Los_Angeles time zone: UTC-8 (PST) or UTC-7 (PDT).
  • Seoul (South Korea) is in the Asia/Seoul time zone: UTC+9 (KST).

Best time to call or meet

Los Angeles and Seoul have no overlap in standard 9-to-5 working hours, so one side needs to start early or finish late. If you stretch the day to 7 AM to 10 PM in both cities, the shared window is 3:00 PM to 10:00 PM in Los Angeles (7:00 AM to 2:00 PM (next day) in Seoul).

The best time to call is around 6:30 PM in Los Angeles (10:30 AM (next day) in Seoul). That time falls outside standard 9-to-5 hours in at least one city. These times use the usual gap; for a few weeks each year, shift them by the difference noted above.
