How to Convert CET to AST
Converting between Central European Time and Atlantic Standard Time means accounting for a 5 hours gap — here's how to do it in under 10 seconds with no sign-up.
Pick the date and time in Central European Time (UTC +1) that you want to convert. Hit "Now" to load the current CET time instantly, or use "+1h" to step forward and compare.
The equivalent Atlantic Standard Time (UTC -4) time appears immediately. Since AST is 5 hours behind of CET, most daytime conversions stay on the same calendar day.

Why Choose Our CET to AST Converter
When someone in Central Europe suggests 2:00 PM CET, that's 9:00 AM AST. This converter shows the overlap so both sides agree on one slot — no back-and-forth.
Late-night CET times can land on a different date in AST because of the 5 hours offset. The converter labels "next day" or "previous day" next to the result so you never send a message a day early or miss a deadline.
Daylight Saving adjustments can widen or narrow the CET–AST gap by an hour. During transition weeks many people get it wrong. This converter pulls the current UTC offsets automatically, so the result is right even on the changeover day.
Product launches, sports matches, and webinars are often announced in CET. Convert the event time to AST so you know exactly when to tune in — with a 5 hours difference, a morning event in Central Europe falls during work hours in Canada.
