Yasumi (Japanese for 'Holiday'「休み」) is the easy PHP library that helps you retrieve the dates and names of holidays and other special celebrations from various countries/states. It is calculation and rule driven avoiding the need of a comprehensive database.

Many services exist that can provide holiday information, however are either not entirely free or only offer limited information. In addition, no exhaustive PHP library exists today covering a wide range of holidays and countries. PEAR's Date_Holidays library was a similar attempt, however it hasn't been updated for a long time.

The goal of Yasumi is to be powerful while remaining lightweight, by utilizing PHP native classes wherever possible. Yasumi's calculation is provider-based (i.e. by country/state), making it easy to add new holiday providers that calculate holidays.
