Islamic Mourning Period Calculator

Calculate the key dates in Islamic mourning — the 3-day condolence period, the 40-day cultural milestone, and the widow's iddah — after a loved one's passing.

Calculate Islamic Mourning Dates

Enter the date of passing to see the 3rd day (end of formal hidad), the 40th day (cultural Arba'een), and the widow's iddah date.

Islam provides a structured framework for mourning that balances the human need to grieve with a theological orientation toward patience (sabr) and trust in God's will (tawakkul). The formal Islamic mourning period is shorter than many Western traditions — just 3 days — but the ongoing remembrance of the deceased through prayer and charity extends far beyond those three days.

Cultural practices in Muslim-majority countries often extend the formal Islamic timeline. The 40-day gathering (called Arba'een in Arab communities, Kırk in Turkish communities) is observed across North Africa, the Middle East, Turkey, and Central Asia as a significant mourning milestone — even though it is a cultural rather than strictly religious observance.

The Iddah Period for Widows

The iddah (عدة) for a widow is 4 months and 10 days from the date of her husband's death — approximately 130 days. This period is established by Quranic verse (2:234) and is a formal religious requirement, not a cultural custom. During iddah, a widow refrains from remarrying, typically avoids perfume and jewelry, and limits social outings. The period ends when she gives birth if she is pregnant at the time of her husband's death.

The iddah is both a protective waiting period (to confirm the absence of pregnancy) and a time of spiritual observation. Many scholars note that the 4-month-10-day period also serves as a mourning interval that honors the depth of the marital bond — a reflection of Islamic jurisprudence's sensitivity to the emotional reality of loss.
