I usually go to bed early, so it is really hard for me stay awake until midnight. And it is so 'not surprising' , to have a midnight birthday cake. Everybody does it. I would love to be surprised if I know it is not expected. But most of the times I know, and it's just not as much fun anymore . I know I sound boring :( . I really like to save cake cutting for the birthday evening to get a better feel of the day and there are more friends and family members who can join.
Oh yes it is. People like to celebrate the birthday by cutting cake when clock strikes 12 and the day actually begins. There are online stores that deliver birthday cake at midnight along with flowers or anything else you want to deliver. Some people also like to call at midnight, so that their wish is the first one.
