How long is the mourning period in Hindu tradition?

The formal ritual mourning period lasts 13 days, called the Sutak period. During this time, the immediate family observes dietary restrictions, avoids temples and celebrations, and performs daily rituals for the departed soul. The mourning period formally ends after the Tehrvin ceremony on the 13th day. Some communities observe additional restrictions through the first month, and annual Shraddha and Pitrupaksha observances continue each year.
