When you create a new post in WordPress, the publish date is set to ‘immediately’, this plugin allows you more control over this behaviour and set a date or time of your choosing.
For example, you can choose to have new posts scheduled for:
<ul>
<li>first Tuesday of next month at 5:30pm</li>
<li>next Monday at 09:00</li>
<li>Friday at 19:30</li>
</ul>
Any format that PHP’s (strtotime)[http://php.net/manual/en/datetime.formats.php] function can understand can be used.
Settings are on a per user basis, just go to your profile page!

Conditional Menus is a simple yet useful WordPress plugin by <a href="https://themify.me/" rel="nofollow ugc">Themify</a>, which allows you to swap the menus in the theme as per specific conditions. In short, you can have different menus in different posts, pages, categories, archive pages, etc. It works with any WordPress theme that uses the standard WordPress menu function.
<h3>How to use it</h3>
Once you activate the plugin, you will see the conditional menus on the Manage Locations tab located in your WP Admin > Appearance > Menus page.
1) To add conditional menu: click “Conditional Menu” and select a menu from the list (you can create these menus in the “Edit Menus” tab) 
 – You can remove the menu by selecting “Disable Menu” from the list. 
2) Click on “+ Conditions” to add conditions in the modal box (tick the checkboxes where you want the menu to appear) 
3) To remove the conditional menus, click on the “X” button
