The ideal time is when the Badrinath temple is open (late April/early May to Oct/Nov). The most auspicious period is Pitru Paksha (the 16-day fortnight dedicated to ancestors, usually Sep/Oct). Performing Pind Daan on the ancestor’s specific death anniversary (tithi) or during Amavasya (new moon days) within the open season is also highly beneficial. It is often recommended to perform Pind Daan at Prayagraj, Kashi, and Gaya before performing it at Brahmakapal, which is considered the final place.
