IST to KST Converter

It takes three quick steps:

1. Click the IST field on the left and pick the time you want to convert.
2. The matching KST time updates on the right automatically — there’s no button to press.
3. Need a different day? Click the date field and the result follows, rolling over if it crosses midnight.

KST is 7 hours ahead of IST. In everyday terms, once you know the time on one side you just add 7 hours to get the other — so a call between Jerusalem and Seoul is always 7 hours apart.

Right now the time in Korea Standard Time (KST) is Tuesday, June 30, 2026 · 2:54:01 AM. It ticks every second, so you’re always looking at the live KST clock.

And in Israel Standard Time (IST), it’s currently Monday, June 29, 2026 · 7:54:01 PM. Compare the two and the 7 hours gap is easy to see.

For example, a 9:00 AM IST meeting takes place at 4:00 PM KST. The trick is to aim for a slot that lands inside normal working hours on both sides. Once you’ve found a time, hit Share on the converter to copy a link with the time built in — easy to send to a colleague. Juggling three or more zones? The meeting planner highlights the hours that overlap for everyone.

The labels IST and KST are fixed offsets, so the result on this page is always exact. One side switches between standard and summer time while the other stays put, so the real-world gap can shift by an hour for part of the year. It's worth checking which label a region is actually using before you lock in a time.

We don’t guess. IST and KST times are worked out from the official IANA time zone database, the trusted standard that operating systems use worldwide. Because daylight-saving rules and regional offsets do change over time, we track those updates rather than relying on a fixed number — which is exactly where many converters slip up.
