Eid

Write a Python Islamic calendar Eid date predictor that calculates the expected dates of Eid al-Fitr and Eid al-Adha for any year. Using the astronomical calculation method: calculate the new moon conjunction date for Shawwal and Dhul Hijjah for any Gregorian year, determine the expected Eid date based on the conjunction plus moon visibility calculation — the Yallop criterion for new crescent visibility at a defined geographic location, generate the predicted Eid date range — accounting for the one-day variation from moon sighting versus calculation differences, and produce a 10-year Eid date calendar showing how the dates shift through the Gregorian calendar and the implications for fasting day length at a defined latitude.
