Hide date at pages

Hey guys,
i have a question and i′m sure that this question is asked in this forum for many many times, but with my bad english a can′t have the right search results because with my litte vocabular i can′t make an inteligent search.

So my question is:
When i make ab Page(not ab post) there is always showing the date of the makeing. I don′t like this, i want only to see the date at the posts not at the normal pages….

how to make it like i want?

hope you can help me ??
