Magha Puja is celebrated on the full moon day of the third lunar month in March. According to legends, after Gautama Buddha's retreat in the Deer Park, Sarnath, Lord Buddha headed towards the Rajagaha City. Around 1250 arahants along with Sariputta and Moggalana reached Veruvana Monastery to pay their respect to Buddha. The Enlightened One delivered a sermon to these worshippers. He recited the Patimokkha. The Magha Puja is thus celebrated to commemorate this event.

History of the Magha Puja
Lord Buddha reached the Rajagaha city on post the first Rains Retreat (Vassa) at the Deer Park in Sarnath, Here, without seeking his consent, 1250 Arahats along with two of his main disciples, Ven. Sariputta and Ven. Moggalana, collected to pay their respect to him at the Veruvana Monastery. To this meeting, Buddha delivered his lecture, or recitation of the Patimokkha. The Magh Day Puja is celebrated to honor this event which took place early in the life of the Buddha.

This day is also known as the Magha Day, Four Fold Sangha or the Sangha Day. The Sangha had four special features. Firstly all the 1250 Buddhist followers were arahants. Secondly, it was Buddha who had ordained all of them. Thirdly all of them had gathered on their own accord. Buddha did not invite them. Lastly all of them had gathered on a full moon day in the Magha (March) month. Hence the Magha Day Puja is also referred to as Four Fold Sangha.
