Why the word "de" in the following sentence

[Stanley Ross]

Hi, I am new to learning French.  Can someone explain to me why in the following sentence, the word "de" is used? 

Tu vas faire quoi DE ton week-end? 

Merci, Stan

I think this is somewhat vernacular, giving a little extra meaning to the more straightforward Tu vas faire quoi ce weekend? or ...le weekend.

It's a bit like "what are you planning to make of your weekend?" It's the OF that is the equivalent of DE.

Salut Stu. Je comprend. Thank you very much. Stan

[Robert HYde]

So Stan, could you tell me what de beaux means?

thanks,

Sheila

I've been taking French for two years. The "de" means "of". Tu vas faire que de ton week-end?= What are you doing this weekend, but it litterally means: you doing what of your week-end?

Salut Mariah, Merci Beaucoup. I really appreciate your response. STan
