Align IST–CET Meetings Instantly

When someone in India suggests 2:00 PM IST, that's 9:30 AM CET. This converter shows the overlap so both sides agree on one slot — no back-and-forth.

Spot Date-Line Shifts at a Glance

Late-night IST times can land on a different date in CET because of the 4 hours and 30 minutes offset. The converter labels "next day" or "previous day" next to the result so you never send a message a day early or miss a deadline.

Handles DST Transitions Automatically

The half-hour offset between IST (UTC +5:30) and CET (UTC +1) already makes mental math tricky — add Daylight Saving Time and the gap can shift further. This converter uses live UTC offsets, so you're always accurate.
