Best time to call Lima from Seoul
For most work calls, compare the normal business day in Seoul (KST) with the business day in Lima (PET). KST commonly covers East Asia, while PET 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 11:00 PM KST, which reaches 9:00 AM PET near the start of their workday.
- DST Safety: Neither KST nor PET 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.
- Lima Stock Exchange (BVL): 09:00-15:00 local time in Lima.

Frequently Asked Questions
What is the time difference between KST and PET?
During standard time, Peru Time is 14 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 Peru observe Daylight Saving Time?
Peru does not observe Daylight Saving Time and has not done so since 1994. PET remains fixed at UTC-05:00 throughout the entire year, with no seasonal clock changes affecting business hours, market schedules, or international coordination.
How does Peru Time (PET) align with the US?
PET (UTC-05:00) is identical to US Eastern Standard Time (EST) during the Northern Hemisphere winter — Lima and New York run on the exact same clock. When the US shifts to Eastern Daylight Time (EDT, UTC-04:00) in summer, PET falls one hour behind, but a full shared workday between Peru and the US East Coast remains entirely achievable without scheduling concessions on either side.
