• IST doesn't change - it's always 5.5 hours ahead of UTC throughout the year
• Business meetings work best when IST is in afternoon (1:30-6 PM) for CET morning hours
• Remember the 30-minute offset - IST uses half-hour timezone unlike most others
• Use 24-hour format to avoid AM/PM confusion when scheduling internationally
• CET transitions to CEST on the last Sunday in March at 2:00 AM

A simple tool for handling two complicated time zones

This converter lets you pick any date and time in either IST or CET/CEST and instantly see what that translates to on the other side. It updates as you type (if auto-convert is on), adjusts for daylight saving in Europe, and shows both current time and UTC offsets. It’s built to give you everything you need without making you think too hard.

Why this matters if you work or connect globally

If you're in India working with a team based in Berlin or Paris, or if you're setting appointments with clients across time zones, timing mistakes can derail things quickly. CET becomes CEST in the summer, and IST doesn’t shift at all. The tool accounts for all of that. No manual calculations, no surprises.

How to use the converter

Pick a starting point

Choose a date and time using the calendar and clock fields. Then select whether you want to start from India or Europe. You can switch directions anytime using the “Swap” button.

Convert automatically or on demand

Want results right as you type? Keep “Auto Convert” checked. Prefer more control? Turn it off and click “Convert Time” whenever you’re ready.

Need the current time?

Tap “Now” and the input fields will fill with the current local time of your chosen starting zone. Super useful for setting up calls in real time.

Prefer 24-hour time?

Click the “Time Format” button to switch between 12-hour and 24-hour formats. Your preference applies across live clocks and converted results.

Built-in features that make scheduling smoother

Handles Europe’s seasonal clock change

Central Europe switches to daylight saving time in March and back again in October. The converter automatically detects this based on your selected date and applies the right offset (UTC+1 or UTC+2) without you needing to know the exact changeover days.

Shows the time difference clearly

Want to know how far apart two zones are on a specific day? The difference is displayed clearly and adjusts for whether Europe is in CET or CEST.

Optional: see UTC offsets

Check the “Show UTC Offset” option to get numeric values like +5:30 or +2:00 listed alongside your results. Useful if you're coordinating with others who use offsets instead of zone names.

Things to keep in mind when converting IST and CET

  • IST is always UTC+5:30, with no daylight saving time adjustments, this makes it steady all year.
  • CET becomes CEST on the last Sunday in March, and switches back in late October.
  • The time gap between IST and Central Europe is either 4.5 or 3.5 hours, depending on the season.
  • Most time zones use whole-hour differences, but IST uses a half-hour offset, this throws off a lot of assumptions.
  • Use the “Swap” button to instantly flip directions without clearing your input.

Perfect for planning between Delhi and Berlin

If you're scheduling a project call between Delhi and Berlin, this tool takes the guesswork out. Say you pick 2:00 PM IST on June 15th. The converter shows you that's 10:30 AM CEST in Germany. Want to see how it shifts in December? Pick a December date and see the output shift to 9:30 AM CET. That’s how easy it becomes to stay synced across seasons and continents.

Let this converter handle the timezone math for you

The IST to CET/CEST converter is here to do one job well, translate time between India and Central Europe without confusion. It updates instantly, accounts for daylight saving time, and offers just the right amount of control to keep your calendar accurate.
