This Library requires java version 8 or above.

The library uses the Khayyam table algorithm with hardcoded exceptions. The algorithm calculates a 128-year cycle offset and checks against a predefined set of leap year positions.

Exception years (1403, 1436, 1469, 1404, 1437, 1470) are handled via HashSet lookups.

Any contribution is greatly appreciated.
