Unlimited power event today or saturday

Hi will the unlimited power event be happening this Thursday? Because last year it didn't happened the end of December due to the overlap of reinforcement day and I was wondering if that won't happened? I miss the unlimited power event and I am hoping that this Thursday it happens for New Years eve and that is still a plan? It say's January 1st is the event but usually we get 2 days to play the event and I was wondering if that is happening this week?
