Eid-ul-Fitr will likely fall on April 10 (Wednesday) in Pakistan as there are high possibilities of sighting of the Shawal crescent on April 9 (Tuesday).
As per the Pakistan Meteorological Department (PMD), the new moon will born at 23:21 on April 8 (Monday) and its age next day after sunset will be between 19 to 20 hours. After sunset, the moon could be visible for more than 50 minutes.
The PMD has predicted clear sky in most parts of Pakistan on April 9 in the evening. Cloudy weather is likely in the northern areas of the country.
As per the prediction, people in Pakistan will observe 29 days of fasting before Eid-ul-Fitr.
Islamic months last 29 or 30 days and the beginning or end depends on sighting of the crescent. Despite having as many months as the Gregorian calendar, the Islamic calendar is nearly 10 days shorter due to it being based on the lunar orbit.
This is why Ramadan falls at a different time every year according to the Gregorian calendar.
