Best time to call São Paulo from Seoul
For most work calls, compare the normal business day in Seoul (KST) with the business day in São Paulo (BRT). KST commonly covers East Asia, while BRT is mainly associated with South America.
⚠️ 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.
⚠️ There is no clean same-day business-hours overlap on 2026-07-05. A practical compromise is around 9:00 PM KST, which reaches 9:00 AM BRT near the start of their workday.
- DST Safety: Neither KST nor BRT 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.
- B3 (Brasil Bolsa Balcão): 10:00-17:00 local time in São Paulo.

Frequently Asked Questions
What is the time difference between KST and BRT?
During standard time, Brasília Time is 12 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 Brazil observe Daylight Saving Time?
Brazil officially abolished Daylight Saving Time by presidential decree in April 2019, ending a practice that had been observed in the country's southeastern states since 1985. BRT has remained fixed at UTC-3:00 every day of the year since then, meaning the B3 stock exchange, federal government, and all Brazilian commercial operations run on a permanent, unchanging offset.
Is BRT the same as Argentina Time (ART)?
BRT (Brasília Time) and ART (Argentina Time) share the identical UTC-3:00 offset and neither country observes Daylight Saving Time, making São Paulo and Buenos Aires permanently synchronized on the same clock. Despite the different official designations, a meeting set for 10:00 BRT in São Paulo falls at exactly 10:00 ART in Buenos Aires — a fixed relationship that never shifts seasonally.
