Sunday was announced Eid in Iran after the new moon of the lunar month of Shawwal was sighted Saturday night.
This year, congregational Eid prayers were not held in many parts of the country due to the coronavirus outbreak.
Eid al-Fitr marks the new lunar month of Shawwal and the end of Ramadan — the ninth month on the Islamic calendar — when Muslims refrain from eating, drinking, smoking, and indulging in anything that is in excess or ill-natured from dawn to dusk.
Muslims believe Ramadan to be an auspicious month for the revelations of God to humankind, given the belief that it was in Ramadan when the first verses of the Holy Quran were revealed to Prophet Muhammad (PBUH).
Most Muslim countries celebrate Eid on Sunday.
