Each page should have a unique class (page id) on the body tag that you can target with css plus the css that would be wrapped around the post date/author info. For example, if a page had a unique id of 24 and the post date/author info was wrapped in a div with a class called page-meta you could hide like:
.page-id-24 .page-meta {
display: none;
}

Hope that helps you out.
this is the page (http://www.dailymotivationcz.com/?page_id=371)
this is the code I amusing
.page-id-371 .page-meta {
display: none;
}
still not working for some reason….
details depend on the currently used theme.
as you hadn’t posted any information about that, the suggestion by @brad Davis could only have been a general good guess.
for your theme, it is:
.page-id-371 .post-meta {
display: none;
}
for further details, please contact your theme’s developer;
