When is the best time to perform Daan for maximum merit?

The most auspicious times for Daan are: Pitrupaksha (the 16-day Shradh fortnight), Amavasya (new moon days), solar and lunar eclipses, Ekadashi, and during Kumbh Mela or Magh Mela at Prayagraj. Daan performed at sacred Teertha Kshetras — especially Triveni Sangam, Gaya, and Kashi — during these times generates merit multiplied many thousands of times compared to ordinary giving.
