Mahavir Janma Kalyanak
Mahavir Janma Kalyanak is one of the most important religious festivals in Jainism. It celebrates the birth of Mahavira, the twenty-fourth and last Tirthankara (supreme preacher) of present Avasarpiṇī. On the Gregorian calendar, the holiday occurs either in March or April. Birth
According to Jain texts, Mahavira was born on the thirteenth day of the bright half of the moon in the month of Chaitra in the year 599 BCE (Chaitra Sud 13). Most modern historians consider Kundagram (which is today's Kundalpur in Muzaffarpur  district of Bihar) as his birthplace. Mahavira was born in a democratic kingdom (Ganarajya), Vajji, where the king was chosen by votes. Vaishali was its capital. Mahavira was named 'Vardhaman', meaning "One who grows", because of the increased prosperity in the kingdom at the time of his birth. In Vasokund, Mahavira is revered by the villagers. A place called Ahalya bhumi has not been ploughed for hundreds of years by the family that owns it, as it is considered to be the birthplace of Mahavira. Legend
Mahavira was born into Ikshvaku dynasty as the son of King Siddhartha of Kundagrama and Queen Trishala. During her pregnancy, Trishala was believed to have had a number of auspicious dreams, all signifying the coming of a great soul. Digambara sect of Jainism holds that the mother saw sixteen dreams which were interpreted by the King Siddhartha. It is said that when Queen Trishala gave birth to Mahavira, Indra, the head of heavenly beings (devas) performed a ritual called abhisheka on Sumeru Parvat, this being the second of five auspicious events (Panch Kalyanakas), said to occur in the life of all Tirthankaras. Celebrations

The idol of Mahavira is carried out on a chariot, in a procession called rath yatra. On the way stavans (religious rhymes) are recited. Statues of Mahavira are given a ceremonial anointment called the abhisheka. During the day, most members of the Jain community engage in some sort of charitable act, prayers, pujas, and vratas. Many devotees visit temples dedicated to Mahavira to meditate and offer prayers. Lectures by monks and nuns are held in temples to preach the path of virtue as defined by Jainism. Donations are collected in order to promote charitable missions like saving cows from slaughter or helping to feed poor people. Ancient Jain temples across India typically see an extremely high volume of practitioners come to pay their respects and join in the celebrations. Ahimsa runs and rallies preaching Mahavira's message of Ahiṃsā (non-violence) are taken out on this day.
