London and Seoul: plan a meeting across time zones
London and Seoul are 8 hours apart (Seoul ahead). See the best meeting time, upcoming holidays and clock-change dates for both.
The time difference
For most of the year, Seoul is 8 hours ahead of London. That gap does not hold all year — here is how it actually moves:
- 1 January to 28 March: Seoul is 9 hours ahead of London
- 29 March to 24 October: Seoul is 8 hours ahead of London
- 25 October to 31 December: Seoul is 9 hours ahead of London
Best time to meet
London and Seoul do not share a normal working-hours window. The best compromise is 8:30 AM in London / 4:30 PM in Seoul — still early or late for whoever is furthest from a normal day, which is the honest trade-off at this distance.
