Convert KST to WAT

WAT is 8 hours behind KST. KST is UTC+9 and WAT is UTC+1.

Best time to schedule a meeting

Standard 9–5 working hours do not overlap at all between KST and WAT. Someone has to take an early or late call — or use asynchronous communication instead.

About KST

Korea Standard Time (KST) is UTC+9. It is used in South Korea, with no daylight saving.

Korea Standard Time is UTC+9, the same as Japan, and South Korea has had no daylight saving since 1988 when it was used for the Seoul Olympics. The two Koreas briefly differed: the North moved to UTC+8:30 in 2015 and returned to UTC+9 in 2018, which is the only time in modern history the peninsula ran on two clocks.

About WAT

West Africa Time (WAT) is UTC+1. It is used in Nigeria, Cameroon, Angola and much of central and western Africa.

West Africa Time is UTC+1 all year, with no daylight saving anywhere that uses it. It covers Lagos, Kinshasa and Luanda — a very large population on a single fixed offset. It matches Central European Time in winter and falls an hour behind it in summer, which means a standing Europe–Nigeria meeting moves twice a year at the European end and never at the African one.

Does this gap change with the seasons?

Neither KST nor WAT shifts with the seasons, so this 8-hour difference holds all year. That is unusual enough to be worth relying on: most cross-continental gaps move twice a year.

This is the reason scheduling systems store an IANA zone such as Region/City rather than an offset or an abbreviation: the zone knows its own rules and the offset does not.
