Calender Archives is a wonderful plugin to display your archive. It is a very straight forward plugin to display all your posts in a big yearly calender with thumbnail images. It also comes with two styles.

The implementation is also very easy as any other plugin.

  1. Upload the plugin to the wp-content/plugins folder and activate it
  2. Add [calendar-archive] short code in one of your page, where you want to display the calender.

There is an options page to modify the basic settings of the plugin, which allows you to

  1. Choose the style
  2. Set the size of the calender boxes.
  3. Change the color of the day box and Weekday.

If you want more customization in the style, you can also edit calendar-layout-2.css.php or calendar-layout-1.css.php and then set it as the style in the plugin settings.
