README
Jalaali Haskell
A few Haskell functions for converting Jalaali (Jalali, Persian, Khayyami, Khorshidi, Shamsi) and Gregorian calendar systems to each other.
About
Jalali calendar is a solar calendar that was used in Persia, variants of which today are still in use in Iran as well as Afghanistan. Read more on Wikipedia or see Calendar Converter.
Calendar conversion is based on the algorithm provided by Kazimierz M. Borkowski and has a very good performance.

isJalaaliLeapYear
Checks whether a Jalaali year is leap or not.
isJalaaliLeapYear :: JalaaliYear > Bool
jalaaliMonthLength
Returns the number of days in a Jalaali year and month.
