WITA vs ADT: what's the time gap?
ADT is 11 hours behind WITA. In everyday terms, once you know the time on one side you just subtract 11 hours to get the other — so a call between Makassar and Halifax is always 11 hours apart.
What's the current time in ADT?
Right now the time in Atlantic Daylight Time (ADT) is Monday, June 29, 2026 · 2:54:02 PM. It ticks every second, so you’re always looking at the live ADT clock.
And what time is it in WITA?
And in Central Indonesian Time (WITA), it’s currently Tuesday, June 30, 2026 · 1:54:02 AM. Compare the two and the 11 hours gap is easy to see.
What's the best time for a WITA–ADT call?
For example, a 9:00 AM WITA meeting takes place at 10:00 PM ADT (−1 day). 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 WITA–ADT difference?
The labels WITA and ADT 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 WITA to ADT conversion?
We don’t guess. WITA and ADT 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 WITA is ADT?

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