The meeting planner highlights the hours that overlap for everyone.
Does daylight saving time change the NDT–ACDT difference?
The labels NDT and ACDT are fixed offsets, so the result on this page is always exact. Both regions move their clocks for daylight saving on roughly the same weekends, so the 13 hours gap usually holds steady right through the year.
How accurate is this NDT to ACDT conversion?
We don’t guess. NDT and ACDT 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.

Do NDT or ACDT use daylight saving time?
Newfoundland Daylight Time (NDT) observes daylight saving, alternating with NST; Australian Central Daylight Time (ACDT) observes daylight saving, alternating with ACST.
Why might the real-world NDT–ACDT difference change during the year?
The labels NDT and ACDT are fixed offsets, so this converter is always exact. But Newfoundland Daylight Time's region switches between standard and summer time, so for part of the year you may actually want NST to ACDT. Always check which label a region is currently using before you schedule.
