Question about old dates on a resume , are they needed?

my resume is really starting to look out of date , being in my 30's it starts to look dated when you say you went to college in 2006 . that was a long time ago and i've never had an employer ask me what year i went to school , so not really sure how or why its even relavant.

and is also old dates for some jobs i had earlier too , not sure how to address this without making resume appear thin on info about me
