This plugin hasn’t been tested with the latest 3 major releases of WordPress. It may no longer be maintained or supported and may have compatibility issues when used with more recent versions of WordPress.

Availability Calendar


The Availability Plugin displays booking availability on a year by year basis.

A full calendar year is displayed, with booked dates highlighted.

It is possible for mulitiple calendars to be created using a single install of this plugin.


  • The availability calendar management page.
  • Availability calendar with default styles.
  • Example showing the addition of shortcodes to a page.
  • Multi-calendar management and plugin settings.


Here we go:

  1. Upload the availability folder to the /wp-content/plugins/ directory.
  2. Activate the plugin through the ‘Plugins’ menu in WordPress.
  3. Use the shortcode [availability] to display the calendar.


How do I manage the availability?

Once logged in to wp-admin, browse to Pages > Availability, here you can select all the booked dates and click save once you are done.

Can I display the current year shown?

Yes, use the shortcode [availability display="year"] within your post or page.

How can I display calendars other than the default one?

Using the shortcode [availability calendar="calendar-id"] will display the calendar created with ID calendar-id.

The ID of any additionally created calendars is the value shown in brackets on the settings page.

When using multiple calendars, how do I show the current calendar name?

The shortcode [availability display="name"] can be used.

How do you select a year to view?

The shortcode [availability display="dropdown"] can be used, this will generate a form with a list of available years.

Alternatively you can use the function call <?php availability_dropdown(); ?> in your template files.

How can I style certain elements?

As of version 0.2.2 you can make use of the class names assigned to certain elements of the calendar.

  • wp-availability
  • year-[1234] – e.g. year-2012
  • year-current
  • year-previous
  • year-next
  • wp-availability-month
  • month-[1-12] – e.g. month-3 for March
  • month-[jan-dec] – e.g. month-mar for March
  • month-current
  • month-previous
  • month-next

For further information please refer to the generated source code of the availability calendar itself.

Hi Steve,thanks for your absolutely perfect availability calendar!I’ve used it since quite a while for my families holiday home and it’s really supereasy and design is so clean… and probably the best lightweight plugin… I noticed, that it only works up to PHP 7.2 (getting no security updates anymore) with WP 6.4.2… Is there any chance, you adjust it to newer PHP versions?Thanks in advance!

Simple and handy plugin to generate a calendar table with days marked as available/not available. I’m using it from years and it still works with WP 4.8.3

Thanks Lucian. **update** now they automatically email the embed code when you create a new calendar Perfect free solution (and to update in the backend) for your availability calendar needs.
