Does daylight saving time change the ADT–ART difference?
The labels ADT and ART 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 ADT to ART conversion?
We don’t guess. ADT and ART 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
What is the time difference between ADT and ART?

Do ADT or ART use daylight saving time?
Atlantic Daylight Time (ADT) observes daylight saving, alternating with AST; Argentina Time (ART) is a fixed offset with no daylight saving.
Why might the real-world ADT–ART difference change during the year?
The labels ADT and ART 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 AST to ART. Always check which label a region is currently using before you schedule.
