Enhanced-Calendar (<a href="http://michaelwalsh.org/blog/2010/12/08/need-to-rename-calendar-plus/" rel="nofollow ugc">previously known as Calendar-Plus</a>) enhances <a href="https://wordpress.org/extend/plugins/calendar/" rel="ugc"> 
Kieran O’Shea’s Calendar plugin</a> by removing several limitations and adding the ability to instantiate 
the calendar in a sidebar widget.


Enhanced-Calendar requires the original 
<a href="https://wordpress.org/extend/plugins/calendar/" rel="ugc">Calendar plugin</a> to be installed and activated. 
Enhanced-Calendar introduces a proper shortcode which can also be used to display the calendar in a sidebar 
by using the <a href="https://wordpress.org/extend/plugins/sidebar-shortcodes/" rel="ugc">Sidebar Shortcode plugin</a>.

<h3>Usage</h3>
Usage of Enhanced-Calendar is primarily driven by shortcodes. Enhanced-Calendar does not change the way 
in which Calendar adds and manages calendar events. The [calendar] shortcode has several arguments. You 
could create a post that contains the following content to see how the various options affect the Calendar 
output:
<pre>[calendar]

[calendar weekday=1]

[calendar weekday=3 descriptions='off']

[calendar dateswitcher='off']

[calendar weekday=3 dateswitcher='off' descriptions='off']
</pre>
<h3>Styling</h3>
Enhanced-Calendar moves the CSS styling from a plugin setting which is stored in the database to a separate CSS 
file which makes it easy to style Calendar with your own WordPress theme. The default CSS file shipped with 
Enhanced-Calendar is the same as the default settings from the Calendar plugin.
