El verbo contar
 

I never seem to understand the verb "contar".

What does this sentence mean?
"Me ha escrito Daniel y ha dicho que la fiesta es el sábado, proque me ha contado que sus padres.."

and

"Os escribo para contaros novedades"

Contar can mean to count (in the sense of counting how many objects there are), to count (in the sense of being relevant), or here to recount (to tell, particularly to tell a story). So "...because he has told me that his parents..." and "I'm writing to you to tell you [my] news".

Daniel has told me : Daniel me a contado or Daniel me ha dicho ^_^

Lee Ying's answer are correct and accurate too.

*corrected spelling*

Tener en cuenta=to keep in mind
Darse cuenta de= to realize

You are right contar has lots of meanings
