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 ACST to ICT?
The labels ACST and ICT are fixed offsets, so the result on this page is always exact. One side switches between standard and summer time while the other stays put, so the real-world gap can shift by an hour for part of the year. It's worth checking which label a region is actually using before you lock in a time.
Why can you trust this ACST to ICT 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 ACST to ICT stays accurate for today and for any past or future date you type in.

Frequently asked questions
How many hours behind ACST is ICT?
ICT is 2 hours and 30 minutes behind ACST — a fixed 2 hours and 30 minutes difference, since both are fixed-offset labels.
What time is it in ICT when it's 12:00 PM ACST?

Do ACST or ICT use daylight saving time?
Australian Central Standard Time (ACST) observes daylight saving, alternating with ACDT; Indochina Time (ICT) is a fixed offset with no daylight saving.
Why might the real-world ACST–ICT difference change during the year?
The labels ACST and ICT are fixed offsets, so this converter is always exact. But Australian Central Standard Time's region switches between standard and summer time, so for part of the year you may actually want ACDT to ICT. Always check which label a region is currently using before you schedule.
