Does anyone know what hour will Mad Men go up on US HBO Max on December 1?

I have a gut feeling it will not be midnight eastern and something like 9pm eastern is the norm of the platform nowadays but I have a little hope! I only ask because the Warner Brothers Press website didn't say a time and journalists copy off the press kit, maybe someone who works for the WB knows? This would be my first time seeing the show and I'm so excited! EDIT: 3am Eastern
