A State of Trance

A State of Trance (often abbreviated as ASOT) is a Dutch trance radio show, hosted by Armin van Buuren and co-producer Ruben de Ronde, that first aired in June 2001. It is currently aired weekly every Thursday at 20:00 (CET) and 14:00 (EST) and as of January 2021, ASOT is broadcast by more than 150 stations in 84 countries claiming a weekly listener count surpassing 40 million.

ASOT is broadcast as a 2-hour livestream with some stations re-airing the entire stream. However, several of its radio affiliates omit the second hour while other stations format the show into two 58-minute segments to make time for local advertising and station branding.
