An evening-to-morning handoff
A late Seoul meeting can be an early New York start. Seoul 22:00 maps to New York 08:00 in November and 09:00 in July. There is little room for a conventional shared workday, so check how early New York participants are willing to begin rather than calling the window universally convenient.

Daylight-saving rules depend on the city and date. When a local hour is missing or repeated, the converter rejects it or asks which occurrence you mean. Rules can change politically; reconfirm far-future meetings.
