What's the current time difference between AEST and IST?

Right now, IST (IST · India Standard Time) is −4.5h relative to AEST (AEST · Australian Eastern Standard Time). The number is live and reflects the current daylight-saving status of both zones.

Does this converter account for daylight saving time?

Yes. The math is done against IANA's tz database via Intl.DateTimeFormat, so DST shifts in either zone show up immediately at the transition. Around DST boundaries the conversion can move by an hour from one week to the next — this page always reflects the current rule.

Why does the TO column sometimes show "+1d" or "−1d"?

When the AEST hour lands on a different calendar day in IST, we flag it so you don't accidentally schedule a meeting on the wrong date. AEST 11 PM is often the next day in eastern-hemisphere zones, for example.

How do I schedule a meeting that works for both zones?

Look at the row highlighted lume green — that's the longest contiguous block where both AEST and IST are in standard working hours (9 AM–5 PM local). Open the planner from the link above to lock a specific time and share a DST-stable link with the other party.
