Quincenera

I am doing a spanish project and it is due Wednesday, and I don`t have anything for it. I have a lot of questions that need to be answered. Please help if you can.

1. When and where does a quincenera take place?
2. How long does it last?
3. What are the festivities that are apart of it?
4. Are there special names for certain characters, foods or festivities in the quincenera different from ours?
5. What is the reason for a quincenera?

Thanks!
