Complete Celebration Reminder is a Joomla extension that displays upcoming celebrations, national holidays, public holidays and name days within a country. For example, users will be able to see a list of the next 10 closest holidays starting from the current day.

The days that are usually included in such a calendar are national holidays, religious name days, international celebration days, annual events, full moons and lunar eclipses, etc. However, the extension can also function more generally as a notebook of simple reminders (text only) for the activities of a company, for the events of a shopping mall, for the matches in a stadium, etc.

Specific examples of websites that could use the extension are news websites, online holiday calendars, flower shops, pastry shops, restaurants, gift shops, online stores, social blogs, etc.
