Time Lord is a plugin which allows you to schedule the publication of part of your content on a set date. It can also calculate age based on a set year in the past or the estimated time if the year is set in the future.
You can use it in posts, pages or any other content type via the <code>[timelord]</code> shordcode. Here are some common examples, supposing that present day is on April 2015:
<ul>
<li><code>[timelord from="2016-01"]SOME CONTENT[/timelord]</code> would output “SOME CONTENT” only when January 2016 comes. </li>
<li><code>[timelord to="2016-01"]SOME CONTENT[/timelord]</code> would output “SOME CONTENT” until January 2016 and then it would remove it. </li>
<li><code>[timelord from="2015-04-01" to="2016-04-01" every="1 day"]SOME CONTENT[/timelord]</code> would output “SOME CONTENT” every other day until April 2016. </li>
<li><code>[timelord from="2015-04-01" to="2016-04-01" every="Monday"]SOME CONTENT[/timelord]</code> would output “SOME CONTENT” every Monday until April 2016. </li>
<li><code>[timelord to="2014-01" del="yes"]SOME CONTENT[/timelord]</code> would output <code><del>SOME CONTENT</del></code> (check screenshot for an example of what the user would actually see in the frontend). </li>
<li><code>[timelord from="2015-01" to="2016-01"]SOME CONTENT[/timelord]</code> would output “SOME CONTENT” from January 2015 to January 2016.</li>
<li><code>[timelord mode="hide" from="2015-01" to="2016-01"]SOME CONTENT[/timelord]</code> would output “SOME CONTENT” every other time except from January 2015 to January 2016.</li>
<li><code>[timelord year="1980"]</code> would output “35”.</li>
<li><code>[timelord year="1980" ordinal="yes"]</code> would output “35th”.</li>
</ul>

WP Reading Time let’s you easily add an estimated reading time to your WordPress posts. Activating the plugin will automatically add the reading time to the beginning of your post’s content. This can be deactivated in the Reading Time settings which can be accessed from your Dashboard’s Settings menu. You can also edit the label and postfix from this menu.
If you’d prefer more control over where you add your reading time you can use the the [rt_reading_time] shortcode to insert the time into a post. This shortcode also excepts values for label and postfix. These are optional. Ex. [rt_reading_time label=”Reading Time:” postfix=”minutes” postfix_singular=”minute”].

Reading Time WP

This is awesome

Easy to setup and get shortcode added. Done in minutes

Just what I needed

Reading Time WP creates an estimated reading time of your posts that is inserted above the content or by using a shortcode.
