Right now I am following the procedure bellow.
For hijri year 1370 and after wards. Moon age should be 9 hours at sun set in Mecca.

And for years before 1370 I am following Yollop's crescent visibility formula. This extends upto Hijri 1st.

This one is looking very promising as it more closely matches to what Saudi Government declares each year.

Execution time: 0.03 render + 0.00 s transfer.
