Time Zone Conversion FAQ
Everything you need to know about converting time between London and Seoul and scheduling across these zones.
During UK winter (Greenwich Mean Time, GMT), Seoul is 9 hours ahead of London. During UK summer (British Summer Time, BST), Seoul is 8 hours ahead of London, as South Korea does not observe Daylight Saving Time.
No, South Korea uses Korea Standard Time (KST, UTC+9) year-round. They do not adjust their clocks for Daylight Saving Time, meaning the time difference with London changes by one hour when the UK switches between GMT and BST.
The optimal overlap for business hours is 9:00 AM to 11:00 AM in London, which corresponds to 5:00 PM to 7:00 PM in Seoul (during GMT) or 4:00 PM to 6:00 PM in Seoul (during BST). This ensures the meeting occurs during standard working hours for both parties.
This converter automatically accounts for British Summer Time (BST). BST runs from the last Sunday in March to the last Sunday in October. During this period, the calculator applies an 8-hour difference. Outside this period, it applies a 9-hour difference.
