"IslamicFatimidCalendar
Concept:
IslamicFatimidCalendar implements the Islamic Fatimid Calendar. The Islamic Fatimid Calendar (also called the Tabular Islamic Calendar) is an arithmetical variation of the Astronomical Islamic Calendar (the one most Muslims use for religious purposes.) It has the same year numbers and months, but the months are determined by arithmetic rules rather than by observation or astronomical calculations. It was developed by early Muslim astronomers of the second Hijra century (the eighth century AD) to provide a predictable time base for calculating the positions of the moon, sun, and planets. Historians use it to convert an Islamic date into a Western calendar date when no other information (like the day of the week) is available. Some Muslims (e.g, the Daudi Bohras, the Isma'ilis) also use the arithmetical calendar for regligous purposes [reference:
http://archive.mumineen.org/publications/oup/bohras.html]. All Muslims commonly use it to estimate future (and sometimes past) dates."
Is that what you want?
