Someone is saying kaddish for his father. The petiyra was on 4 Tishrei 5786 / Friday, September 26, 2025. The Kevura was on Sunday September 28, 2025 / 6 Tishrei 5786. When is the last kaddish? Thank you

Shalom, Thank you for your question. Kaddish is recited for 11 months, as the punishment for the wicked in Gehenom is at most 12 months, and one does not want to proclaim that their parents were so wicked as to attain a full 12 months there. So even though the mourning is for one year, the kaddish is only for 11 months. The 11 months are counted from the day of the burial, and not the passing. So, in your case, the date of the burial was the 6th of Tishrei – therefor they will recite their last kaddish on the 5th of Ellul (Tuesday, 18th August - up to and including Mincha), which is the last day of 11 months of reciting kaddish, which they started on the 6th of Tishrei, on the day of the burial. May his memory be a blessing for all.
