Seoul is 16 hours ahead of San Francisco

Best overlap: 4:00 PM to 6:00 PM in San Francisco is 8:00 AM to 10:00 AM in Seoul.

For the smoothest call, aim inside 4:00 PM to 6:00 PM in San Francisco, i.e. 8:00 AM to 10:00 AM in Seoul. With only around 2 hours of shared time, be precise — book 4:00 PM in San Francisco (8:00 AM in Seoul) and you'll catch both teams. Remember Seoul is a day apart — the next day — so a late call for San Francisco could be the following morning there. Don't be caught out by clock changes — San Francisco observes daylight saving and Seoul doesn't, so the offset varies by an hour through the year.
