How does daylight saving affect AST to EDT?
The labels AST and EDT 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 match usually holds steady right through the year.
Why can you trust this AST to EDT converter?
Every conversion here is calculated from the IANA time zone database — the same source your phone, computer, and browser rely on. Plenty of tools hard-code a single offset, which quietly goes wrong whenever a region changes its rules or flips for daylight saving. We follow the real rules instead, so AST to EDT stays accurate for today and for any past or future date you type in.

Frequently asked questions
What is the time difference between AST and EDT?
There is no time difference — AST and EDT share the same UTC offset (UTC-4), so the times are identical.
What time is it in EDT when it's 12:00 PM AST?
When it's 12:00 PM (noon) AST, it's 12:00 PM EDT.
Do AST or EDT use daylight saving time?
Atlantic Standard Time (AST) observes daylight saving, alternating with ADT; Eastern Daylight Time (EDT) observes daylight saving, alternating with EST.
Why might the real-world AST–EDT difference change during the year?
The labels AST and EDT 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 EDT. Always check which label a region is currently using before you schedule.
