IST vs AEDT: what's the time gap?

AEDT is 10 hours ahead of IST. In everyday terms, once you know the time on one side you just add 10 hours to get the other — so a call between Dublin and Sydney is always 10 hours apart.

What time is it in AEDT right now?

Right now the time in Australian Eastern Daylight Time (AEDT) is Tuesday, June 30, 2026 · 4:53:59 AM. It ticks every second, so you’re always looking at the live AEDT clock.

What time is it in IST right now?

And in Irish Standard Time (IST), it’s currently Monday, June 29, 2026 · 6:53:59 PM. Compare the two and the 10 hours gap is easy to see.

What's the best time for a IST–AEDT call?

For example, a 9:00 AM IST meeting takes place at 7:00 PM AEDT. The trick is to aim for a slot that lands inside normal working hours on both sides. Once you’ve found a time, hit Share on the converter to copy a link with the time built in — easy to send to a colleague. Juggling three or more zones? The meeting planner highlights the hours that overlap for everyone.

How does daylight saving affect IST to AEDT?

The labels IST and AEDT are fixed offsets, so the result on this page is always exact. Both regions move their clocks for daylight saving on roughly the same weekends, so the 10 hours gap usually holds steady right through the year.

Why can you trust this IST to AEDT converter?

Every conversion here is calculated from the IANA time zone database — the same source your phone, computer, and browser rely on. Plenty of tools hard-code a single offset, which quietly goes wrong whenever a region changes its rules or flips for daylight saving. We follow the real rules instead, so IST to AEDT stays accurate for today and for any past or future date you type in.

Frequently asked questions

How many hours ahead of IST is AEDT?

AEDT is 10 hours ahead of IST — a fixed 10 hours difference, since both are fixed-offset labels.

What time is it in AEDT when it's 12:00 PM IST?

When it's 12:00 PM (noon) IST, it's 10:00 PM AEDT.

Do IST or AEDT use daylight saving time?

Irish Standard Time (IST) observes daylight saving, alternating with GMT; Australian Eastern Daylight Time (AEDT) observes daylight saving, alternating with AEST.

Why might the real-world IST–AEDT difference change during the year?

The labels IST and AEDT are fixed offsets, so this converter is always exact. But Irish Standard Time's region switches between standard and summer time, so for part of the year you may actually want GMT to AEDT. Always check which label a region is currently using before you schedule.
