Site Meta description

I was wondering why Google indexes my wordpress website with the date added to meta description?
The meta looks like this:
“30 Ian 2011 … Pentru Romanii din UK Anglia exista acum Noi Romani in UK un site cu articole de munca in UK, Romanians in UK, pentru romani online prieteni …”

Can anyone help me to trace the problem? I don’t want the date in front of the site description…
