The best time aligns with the Badrinath temple opening season, typically from late April/early May to October/November, before heavy snowfall closes access. Within this period, Pitru Paksha (the 16-lunar day fortnight dedicated to ancestors, usually falling in September/October) is considered the most auspicious time, drawing large crowds. Performing Tarpan on the specific death anniversary (tithi) or during Amavasya (new moon days) occurring within the open season is also highly recommended for enhanced spiritual merit
