Greg, the only way to change a date to my knowledge is to put the post in draft and then re-post it.  This will not remove the date but it can give you a more current date if you go back and edit and update a post.  I am not sure with all the changes to AR if that is still the case.  Last one I did like that was a post from 2010 and I updated it in July 2014.  This is the only thing I know of, but it will not remove the date.

I have no idea.

 Why would you want to do that? It makes no sense. To answer your question, I don't think so.

I have to ask.... Why?

It just never occurred to me to publish a date-less post.

Yes.  I have seen many bloggers post without dates and have even suggested that they include dates but they don't want to for various reasons.  I have not enquired how they do this feat on their blog.

I don't think so and wonder why you would want that?

Why do you not want a blog dated?

      You could email support at ActiveRain and maybe they will tell you.

      FWIW, I'm not a coder, but I believe that AR has the time and date programmed into the source code.  Below is an example/excerpt:

< div class="blog-date" >
        < time >December 14, 2015 01:44 PM< /time >
        < meta itemprop="datePublished" content="2015-12-14T13:44:32"/ >
      < /div >

Do not think so

Greg,

Why would you not want to have a date on it?  A

Not that I know of.

No blogs are automatically dated and time stamped, but you can choose to post it later.

I think not. Part of the blog editor is recording the date and time. Why would you want it to not have a date?

All blogs have a date that they were published. I have not had one yet that wasnt

Not that I am aware of.  Would love to know how if you find out.

Not that I know of.  A time/date stamp are automatically generated.

I think that it is automatic.

Greg - I don't think it is an option to leave the date out of a blog post, but I would imagine someone smarter than myself might be able to figure out how.

Greg, Not that I know of ... and wonder why you would want to post something without a date.
