These are just a few examples of sites using the Ajax Availability Calendar script.
If you would like to see your website listed here, drop me a line via the contact form and I will consider including it.


The script (version 3) has been downloaded 92847 times since Feb 2010.
Unfortunately I don't have any official figures as to how many sites are using the calendar, but estimates from a specific keyword search in Google makes me believe there are over 5000 sites currently using the calendar.

Important - PHP 8

There is an issue with the script in PHP 8 which is causing the calendar to not display properly.
Here is a quick fix for existing versions (no need to update):

In ac-includes > common.inc.php and change line 16 (latest version) from this:

//error_reporting(E_ALL ^ E_NOTICE);
to this:
error_reporting(0);

This code turns of PHP error reporting just for the calendar script.

Coming soon!

The new version front-end features:
  • No JavaScript libraries
  • No images
  • No iFrames - code loaded via JS
  • Simple CSS
  • Responsive:
    • Automatically calculates the number of months to show.
    • The code recalculates the number of months to show the browser window is resized.
  • Uses built-in PHP functions and data to define local language texts.

Help with installation?

The calendar script is very simple to set up on your server. However, if you prefer, I can install the calendar on your server for you.
Requirements: I will of course also require ftp access to your server. The cost for this service is 40 Euros * (payable via Paypal) however this may need to be adjusted if you have "special" installation requirements.
If you are interested in this option, don't hesitate to contact me via my contact form. I will get back to you as soon as possible.
