Both Eid al-Fitr and Eid al-Adha follow a period of 10 holy days or nights: the last 10 nights of Ramadan (Eid al-Fitr), and the first 10 days of Dhu al-Hijjah (Eid al-Adha). The Night of Power, one of the last 10 nights of Ramadan, is the holiest night of the year. Conversely, the Day of Arafah, the day before Eid al-Adha, is the holiest day of the Islamic year.
