5th - Birthday of Sayyida Zaynab (pbuh)
13th - Possible Wafat day of Sayyida Fatima Zahra (pbuh)
There are different narrations regarding the martyrdom of Sayyida Fatima (pbuh) . But the two dates which are considered most acceptable among scholars are the ones known popularly as the first Fatimiyya (13th Jamadi al-Awwal) and the second Fatimiyya (3rd Jamadi al-Thani). The best way to mourn for her is to speak about her virtues as well as her sufferings and to present her ethical and moral examples.
