Everything you need for AST to WIT — the difference, the current times, and how to plan around it.
How does the AST to WIT converter work?

How many hours apart are AST and WIT?
WIT is 13 hours ahead of AST. In everyday terms, once you know the time on one side you just add 13 hours to get the other — so a call between Halifax and Jayapura is always 13 hours apart.
What's the current time in WIT?
Right now the time in Eastern Indonesian Time (WIT) is Tuesday, June 30, 2026 · 2:53:57 AM. It ticks every second, so you’re always looking at the live WIT clock.
And what time is it in AST?
And in Atlantic Standard Time (AST), it’s currently Monday, June 29, 2026 · 1:53:57 PM. Compare the two and the 13 hours gap is easy to see.
Planning a meeting across AST and WIT?
For example, a 9:00 AM AST meeting takes place at 10:00 PM WIT. 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 AST–WIT difference?
The labels AST and WIT 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 AST to WIT conversion?
We don’t guess. AST and WIT 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 ahead of AST is WIT?
WIT is 13 hours ahead of AST — a fixed 13 hours difference, since both are fixed-offset labels.
What time is it in WIT when it's 12:00 PM AST?
When it's 12:00 PM (noon) AST, it's 1:00 AM WIT the next day.
Do AST or WIT use daylight saving time?
Atlantic Standard Time (AST) observes daylight saving, alternating with ADT; Eastern Indonesian Time (WIT) is a fixed offset with no daylight saving.
Why might the real-world AST–WIT difference change during the year?
The labels AST and WIT are fixed offsets, so this converter is always exact. But Atlantic Standard Time's region switches between standard and summer time, so for part of the year you may actually want ADT to WIT. Always check which label a region is currently using before you schedule.
