IST to ICT 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 ICT 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.

ICT is 1 hour and 30 minutes ahead of IST. In everyday terms, once you know the time on one side you just add 1 hour 30 min to get the other — so a call between Mumbai and Bangkok is always 1 hour 30 min apart.

Right now the time in Indochina Time (ICT) is Tuesday, June 30, 2026 · 12:54:01 AM. It ticks every second, so you’re always looking at the live ICT clock.

And in India Standard Time (IST), it’s currently Monday, June 29, 2026 · 11:24:01 PM. Compare the two and the 1 hour 30 min gap is easy to see.

For example, a 9:00 AM IST meeting takes place at 10:30 AM ICT. 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 ICT are fixed offsets, so the result on this page is always exact. Neither side changes its clocks for daylight saving, so the difference you see here is the same in summer and winter.

We don’t guess. IST and ICT 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.
