Both holidays occur on dates in the lunar Islamic calendar, which is different from the solar based Gregorian calendar, so they are observed on different Gregorian dates every year. There are a number of other days of note and festivals, some common to all Muslims, other specific to Shia Islam as a whole or branches thereof. 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.
