what's the problem any idea?

Answer 1

If you translate the page to English (using Google Translate) then you have the text 01 مهر 97 at the top - that certainly looks like it has something to do with it.

As @Stephen suggested in comments they often fish the date out from on-page content - using some kind of "clever" (but seemingly flawed) algorithm.

Answer 2

The reason might be is that you just updated your dates recently, now you have to wait until Google recrawls your site or you can force Google to recrawl your website

To force Google to recrawl your site (usually takes several minutes):

1. Add your website is added to WebMasters console if it's not added,
2. then just go to: https://www.google.com/webmasters/tools/googlebot-fetch
3. then fetch the page you want to recrawl or you can fetch the whole website

You can use this tool to perform a Meta tags analysis, and check what is the date if your date is shown correctly, then just follow the steps I mentioned above to make it appear on the search results

Update:

After reading @MrWhite's answer, I think that's the reason, it's inside a large-post-meta and you stated a date in it.

This is what I found by looking at the source of your page is that you have this div that has a date next to it

<div class="large-post-meta text-center">
<span class="avatar">نویسنده : نازنین صباحی</span>
<span><i class="fa fa-clock-o"></i> ۰۱ مهر ۹۷</span>
<span><a href="single-1.html#comments"><i class="fa fa-comments-o"></i> 0</a></span>
<span><i class="fa fa-eye"></i> 16</span>
</div>

as you can see, it's a div with a post class: <div class="large-post-meta text-center"> that has a date in it in this span tag: <span><i class="fa fa-clock-o"></i> ۰۱ مهر ۹۷</span>.

So I would advise you to use a Schema Markup to force define your date and anyother information instead of Google just trying to guess it.

So your date schema markup is going to be something like this:

  <meta itemprop="datePublished" content="2009-05-08">May 8, 2009

You can test it, and even try to add missing schemas using Structured Data testing Tool and Structured Data Markup Helper provided by Google.
