//! //! module Calendar
//! //! This is the islamic calendar. Due to some sources, //! they decide the first day of the new months on a //! month-to-month basis (sightings of the new moon), //! so it's probably not <i>that</i> accurate. If //! someone can confirm (or deny) accuracy better than that, //! please contact me so I can change this statement. //! //! It's vaugely based on rules presented in algorithms by //!
