How to Convert AST to IST
Converting between Atlantic Standard Time and India Standard Time means accounting for a 9 hours and 30 minutes gap — here's how to do it in under 10 seconds with no sign-up.
Pick the date and time in Atlantic Standard Time (UTC -4) that you want to convert. Hit "Now" to load the current AST time instantly, or use "+1h" to step forward and compare.
The equivalent India Standard Time (UTC +5:30) time appears immediately. Since IST is 9 hours and 30 minutes ahead of AST, most daytime conversions stay on the same calendar day.
Click "Copy Time" to grab the IST result for your calendar or message. Use "+1d" to check how the conversion shifts across dates — useful when Daylight Saving Time changes the gap.
Why Choose Our AST to IST Converter
With 9 hours and 30 minutes between AST and IST, business-hours overlap is limited. This tool instantly shows which hours work on both sides, so you can lock in a meeting without a chain of "does 3 PM work for you?" emails.
Late-night AST times can land on a different date in IST because of the 9 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.
The half-hour offset between AST (UTC -4) and IST (UTC +5:30) 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.
Product launches, sports matches, and webinars are often announced in AST. Convert the event time to IST so you know exactly when to tune in — with a 9 hours and 30 minutes difference, a morning event in Canada falls during work hours in India.
