Is Pitru Paksha the only time Shradh can be performed?

No. While Pitru Paksha (Sep 7–21, 2026) carries the highest merit, Shradh can be performed on any Amavasya (new moon) day, on the death anniversary (tithi), or on any day at a sacred teertha. The Teerth Shradh package is available year-round — the location itself amplifies the merit.
