fireworks at midnight

It is currently 11:51 pm on a Tuesday night. I am wide awake because there is a commotion going on outside my window. I just opened the curtains and found the street behind my house teeming with Chinese people, fireworks in tow. Evidently this is a day they pay homage to their ancestors by setting off fireworks at midnight. Aren't their ancestors asleep already? Won't they anger them by waking them up? Oh wait...that's just me. :)
