Astronomical forecasting of religious events, such as Eid-ul-Fitr, involves a meticulous analysis of celestial phenomena to determine significant dates. In the case of Eid-ul-Fitr 2024, astronomers predict a synchronicity in its observance in both Pakistan and Saudi Arabia. This alignment is attributed to several astronomical occurrences, primarily a solar eclipse on April 8, which obscures the sun in Saudi Arabia. During this eclipse, the new moon interposes itself between the sun and the earth, casting a shadow over the region. This celestial event plays a crucial role in determining the commencement of Eid-ul-Fitr.
The age of the moon by sunset on April 9 is a critical factor in the calculation. Astronomers note that the moon will have aged 20 hours by this time, indicating its position in its lunar cycle. This information is essential in predicting the visibility and phase of the moon during Eid-ul-Fitr.
Moreover, experts highlight the significance of the crescent moon’s visibility, estimated at 0.5%. The slender crescent marks the beginning of the lunar month and serves as a visual cue for the start of Eid-ul-Fitr festivities. Astronomical calculations help ascertain the precise timing of this event, ensuring uniformity in its observation across different regions.
