Earlier this week a mysterious countdown clock was added to the AC/DC official website.

The clock doesn’t give any indication as to what it is counting down too, just asking fans the question “ARE YOU READY”.

Some fans have already done the math and have determined the countdown clock will expire this upcoming Monday February 12th at 3:00 AM Eastern Time.

The vague message has fans speculating what this all means, the leading theory is that this is the band’s way of announcing a new tour.

This would be significant since the last time the Australian music group toured was  back in 2016 with their “Rock or Bust World Tour”
