Iranian Islamic Republic Day (Persian: روز جمهوری اسلامی‎) is Farvardin 12 that known as Ruz e Jomhuri ye Eslāmi.[1] This day is a national[2] and a public holiday in Iran.[3][4][5] On Iranian Solar Hijri calendar, this day is registered as the anniversary of the 1979 establishment of the Islamic Republic and celebrated by people.[6] Two months after victory of the Islamic Revolution on 1979, the new government held the Iranian Islamic Republic referendum on the 10th and 11th of Farvadin (30th and 31 March) for changing the Pahlavi dynasty with an Islamic Republic. On 12 Farvadin, the referendum results were announced, with 98.2 percent of the Iranians voting for an Islamic Republic.[7][2][8]

Before the referendum, some political groups suggested various name for the ideology of the revolution, such as a Republic (without Islam) or democratic republic. But Ruhollah Khomeini, the founder of the Islamic Republic of Iran, asked the people to vote for an the Islamic Republic, not a word more and not one less word.[8][9]

12 Farvardin is a book about events of Islamic Republic Day by Saeed Zahedi. Also other books were published about this day.[10]

12 Farvardin is also the day of the Martyrdom of Imam Ali al-Najqi al-Hadī.[11]

The day usually falls on April 1, however, as it is determined by the vernal equinox, the date can change if the equinox does not fall on March 21. In 2016, it was on March 31,[12] and in 2017 the date was back to April 1.[13]
