KST to IST
Seoul is 3 hours 30 minutes ahead of India in every season. 1:00 PM in Seoul is 9:30 AM in Chennai, Noida and Bengaluru, and because neither country uses daylight saving time the gap is the same in January and July.
Korean industry in India
Few country pairs share as many factory floors. Samsung's plant in Noida, near Delhi, is one of the largest mobile phone factories in the world, and its research center in Bengaluru is among Samsung's biggest outside Korea. Hyundai has built cars near Chennai since 1998, and its Indian arm listed on the stock market in 2024 in what was then the largest IPO in India's history. Kia, LG and Korean steel and shipping firms add thousands more daily calls.
On the consumer side, Korean dramas and K-pop have a large following in India, especially in the northeast. A 6:00 PM KST music release is 2:30 PM in India, comfortable afternoon viewing, which is one reason Indian fan communities are so active online.

Plan around the Korean afternoon
Korean offices break for lunch from about noon to 1:00 PM, which is 8:30 to 9:30 AM in India, before most Indian offices are busy. The productive overlap starts after that: 1:00 to 6:00 PM in Seoul is 9:30 AM to 2:30 PM in India. Indian teams who want to reach Seoul the same day should send questions before mid-morning India time, because 2:30 PM in India is already 6:00 PM in Korea.
Seoul's midnight is 8:30 PM in India, so evening releases and cut-offs in Korea land late in the Indian working day of the date before. Japan keeps the same UTC+9 offset as Korea, so the Japan to India page gives identical times.

Frequently asked questions
- What time is 9 AM in Seoul in India?
- 5:30 AM in India. The 3.5-hour gap never changes, so this holds all year.
- Does the Korea–India time gap ever change?
- No. South Korea has stayed on UTC+9 since 1988 and India on UTC+5:30 without daylight saving, so the difference is fixed.
- What are good meeting hours between Seoul and Bengaluru?
- Between 1:00 and 5:00 PM in Seoul, which is 9:30 AM to 1:30 PM in Bengaluru. It avoids the Korean lunch hour and the end of the Korean day.
- Is Korea time the same as Japan time?
- Yes. Korea Standard Time and Japan Standard Time are both UTC+9 with no daylight saving, so Seoul and Tokyo always show the same clock time.
