There are three handy checkboxes under Conversion Settings:

Auto Convert: Turn this on to instantly update the result as you change the time or date.

Show Seconds: Toggle this if you want exact seconds in the output.

3. Use the tool buttons for speed

Along the middle of the tool, four buttons help speed things up:

Common scenarios this calculator handles well

Let's say you're in Chennai, India and trying to schedule a call with someone in Singapore. You plan it for 7:00 PM IST. Punch it into the converter and you’ll see it lands at 9:30 PM SGT. Need to reverse that? Hit the swap button and plug in the Singapore time instead. You’ll get the IST equivalent instantly. This is especially useful if you’re managing a global team or working with partners across Asia.

Small touches that help you avoid mistakes

If you accidentally leave the date or time blank, the tool resets the output to placeholder dashes, keeping things clear.
Late-night times in IST (after 9:30 PM) may roll over into the next day in SGT. The tool accounts for that and adjusts the date accordingly.
If you're using keyboard shortcuts, the tool supports them: try Space or Enter to convert, "S" to swap, and "R" to reset.

Stay aligned between India and Singapore every time

This converter removes the guesswork from working across IST and SGT. Whether you're coordinating product launches, live events, or just a casual catch-up between friends in Mumbai and Singapore, you can trust that the timing will line up exactly.
