Julian date calculations and calendar conversions for Swift
License: MIT License
This library is fantastic. I was dreading this part of my project the most, but this made it so much easier. Especially appreciate the references to where you got the algorithms for your calculations. Cheers!
This is in the source:
/// This JDN corresponds to January 1, 45 BCE in the Julian calendar.
public static let effectiveJulianDayNumber: JulianDayNumber = 1704987
However in wikipedia have this interesting statement:
The proleptic Julian calendar is produced by extending the Julian calendar backwards to dates preceding AD 8 when the quadrennial leap year stabilized.
So I suspect that the isProleptic
for the Julian Calendar calculates this wrongly.
