The Islamic Hijri calendar, a lunar system, determines the dates of Ramadan and Eid al-Fitr. Unlike the solar Gregorian calendar, it’s based on the moon’s cycles, causing Ramadan to shift approximately 10-12 days each year. This lunar nature necessitates moon sightings to confirm the start and end of Ramadan, making astronomical calculations and local observations crucial for accurate date predictions, including for Ramadan 2025.
