The meeting planner highlights the hours that overlap for everyone.
How does daylight saving affect CAT to ACST?
The labels CAT and ACST 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 CAT to ACST 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 CAT to ACST stays accurate for today and for any past or future date you type in.

Central Africa Time (CAT) is a fixed offset with no daylight saving; Australian Central Standard Time (ACST) observes daylight saving, alternating with ACDT.
Why might the real-world CAT–ACST difference change during the year?
