How to hide blog date header

Update: There is an easier way to do this without editing the template directly. See Blogger "Edit posts" options

I have tested "unticking" the date header by testing at Testing Blogger Beta without editing directing the template directly at Testing Blogger Beta and you can check a label page eg Label: Comments you would see that there are no date header. Also read the comment: puluth® has left a new comment on your post "How to hide blog date header":

Thanks. but how to remove it from blogger label page?

While blogs started as web logs or weblogs (chronological publication of personal thoughts or diary) and thus characteristically have a date header like the one above this post, but because blogs have now become a convenient way of putting content online, many have been using blogs for other purposes more like a typical website, many bloggers want to get rid of the typical date header.

That is not difficult to do. Sign into Dashboard > Design > Edit HTML to open the template editor and look for the block of code like the one below (for the Minima template, yours depending on your template may be slightly different):

/* Posts
-----------------------------------------------
*/
h2.date-header {
margin:1.5em 0 .5em;
}

and just add this line: visibility:hidden; for example like below:

/* Posts
-----------------------------------------------
*/
h2.date-header {
visibility:hidden;
margin:1.5em 0 .5em;
}

and the date header will be gone.
