Can I perform both Dwadashi Shradh and Magha Shradh on October 7, 2026?

Yes. Since both Dwadashi Shradh and Magha Shradh fall on October 7, 2026, a family may need to perform both if they have ancestors who died on Dwadashi Tithi and ancestors who died under Magha Nakshatra. A pandit will sequence the rituals appropriately within the Aparahna window.
