Is Magha Purnima (January–February) a good alternative to Pitru Paksha for Teerth Shradh?

Yes, absolutely. The full moon of Magha at Prayagraj is described in the Puranas as one of the most auspicious occasions for holy bathing and ancestral rites. The weather in January–February is pleasant and comfortable for travel, crowds are much lower than in October, and flight fares from NRI hubs are significantly cheaper. It is our most recommended alternative window for NRIs who cannot travel in September–October.
