How many hours apart are ACDT and CAT?
CAT is 8 hours and 30 minutes behind ACDT. In everyday terms, once you know the time on one side you just subtract 8 hours 30 min to get the other — so a call between Adelaide and Harare is always 8 hours 30 min apart.
What's the current time in CAT?
Right now the time in Central Africa Time (CAT) is Monday, June 29, 2026 · 7:54:05 PM. It ticks every second, so you’re always looking at the live CAT clock.
And what time is it in ACDT?
And in Australian Central Daylight Time (ACDT), it’s currently Tuesday, June 30, 2026 · 4:24:05 AM. Compare the two and the 8 hours 30 min gap is easy to see.
When is a good time to schedule a ACDT to CAT meeting?
For example, a 9:00 AM ACDT meeting takes place at 12:30 AM CAT. 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.
Does daylight saving time change the ACDT–CAT difference?
The labels ACDT and CAT 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.
How accurate is this ACDT to CAT conversion?
We don’t guess. ACDT and CAT times are worked out from the official IANA time zone database, the trusted standard that operating systems use worldwide. Because daylight-saving rules and regional offsets do change over time, we track those updates rather than relying on a fixed number — which is exactly where many converters slip up.

Frequently asked questions
How many hours behind ACDT is CAT?
CAT is 8 hours and 30 minutes behind ACDT — a fixed 8 hours and 30 minutes difference, since both are fixed-offset labels.
What time is it in CAT when it's 12:00 PM ACDT?

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