Best time to call Johannesburg from Seoul
For most work calls, compare the normal business day in Seoul (KST) with the business day in Johannesburg (SAST). KST commonly covers East Asia, while SAST is mainly associated with Southern Africa.
⚠️ Note: 2026-07-05 is not a normal workday in one or both regions based on their configured calendar. The overlap below should be treated as a reference, not a guaranteed office-hours window.
✅ The most practical overlap on 2026-07-05 is usually 4:00 PM - 6:00 PM KST, which corresponds to 9:00 AM - 11:00 AM SAST. This window sits inside the typical KST workday (9:00 AM - 6:00 PM) and the SAST workday (9:00 AM - 5:00 PM).
- DST Safety: Neither KST nor SAST uses Daylight Saving Time in our dataset, making business-hour relationships stable year-round.
- Korea Exchange (KRX): 09:00-15:30 local time in Seoul.
- Johannesburg Stock Exchange (JSE): 09:00-17:00 local time in Johannesburg.

Frequently Asked Questions
What is the time difference between KST and SAST?
During standard time, South African Standard Time is 7 hours behind Korea Standard Time.
Does South Korea observe Daylight Saving Time?
South Korea does not observe Daylight Saving Time and has not done so since 1988, when DST was discontinued following the Seoul Summer Olympics. KST remains fixed at UTC+9:00 every day of the year, meaning the offset between Seoul and any DST-observing country shifts by one hour twice annually when those countries change their clocks.
Are KST and JST the same?
Yes, Korea Standard Time (KST) and Japan Standard Time (JST) share the identical UTC+9:00 offset, and neither country observes Daylight Saving Time. Seoul and Tokyo run on exactly the same clock year-round, which directly supports the deep semiconductor, automotive, and consumer electronics supply chain integration between the two economies.
Does South Africa observe Daylight Saving Time?
South Africa does not observe Daylight Saving Time and has not done so since 1944, remaining permanently fixed at UTC+2:00 every day of the year. This means that when European countries advance to CEST (UTC+2) each spring, SAST and Central European Summer Time reach an identical offset — a zero-difference alignment that makes South Africa one of Europe's most time-convenient offshore business partners during summer months.
Is SAST the same as European time?
SAST (UTC+2) matches Central European Summer Time (CEST, UTC+2) exactly during the European summer from late March to late October — meaning Johannesburg and Berlin, Paris, and Rome run on the same clock for roughly seven months of the year. During European winter, when the continent reverts to CET (UTC+1), SAST moves 1 hour ahead of Frankfurt and Paris, and 2 hours ahead of London (GMT, UTC+0).
