Fatimiyya are days when Shia Muslims mourn the martyrdom of Fatima, the daughter of the Islamic prophet Muhammad. Fatimiyya is a window between the two possible dates of her death, that is, from the 13th of Jumad al-Awwal to the 3rd of Jumad al-Thani. Specifically, the Fatimiyya period is six days in total, three days in the month of Jamadi al-Awal and three days in the month of Jumada al-Thani. This means that the first Fatimiyya is 13-15 Jumada al-Awwal and the second Fatimiyya is 3-5 Jamadi al-Thani. Instead of three, some Shia Muslims mourn for ten days.
Although there is no fixed convention, Fatimiyya periods such as the "first ten days" (10-20 Jumada al-Awwal) or the "second ten days" (1-10 Jumada al-Thani) have been increasingly commemorated by Shia Muslims in recent years they are very fond of the first ten days of Muharram, which are traditionally associated with the martyrdom of Hussein. Fatimah's prominent place in Islam as the daughter of the Islamic Prophet Muhammad, the hardships she endured in her short life, and the fact that she gave her life to defend the first Shia imam, Ali, are some of the reasons why Shia Muslims give an annual commemoration of Fatimah.
In addition to Iran and Iraq, Fatimiyya is also observed in other countries, including India, Pakistan, Australia, Azerbaijan and Tajikistan. There are also events organized in Europe by the Islamic Center in Hamburg, Germany, the Islamic Center in England, and others in Sweden and elsewhere.
