The Light Development Holiday Library is a Java class library that models any kind of holiday as an event in the gregorian calendar system. It simplifies the high complexity of holiday definition by matching all different holiday classes against the same single common interface taking away the need to know about each and every detail of computation, calendar systems and algorithms.

Most major types and calendars supported

The library models different holiday classes over the gregorian, julian, islamic, hindu, hebrew and chinese calendar systems. The combination of classes (i.e. computation methods) and calendar systems models holidays observerd by the majority of world population.

Additional support for Persian and Coptic calendar systems and holidays is in preparation, making the Holiday Library the most comprehensive and common tool for modeling and occurence determination of holidays.

Simple integration, high scalability

The library can easily be incorporated in various applications, let it be local standalone applications, server based online or web applications and complex integrated systems too. It serves to end user functionality and for backend purposes scaling perfectly from mobile via desktop to server and host environments.
