Mahavir Jayanti is an important religious holiday in Jainism that celebrates the birth of Mahavira, the last Tirthankara. According to Jain beliefs, Mahavira was born in 599 BCE to King Siddhartha and Queen Trishala. During her pregnancy, Trishala had sixteen auspicious dreams that were interpreted as meaning her child would become an emperor or Tirthankar. When Mahavira was born at four in the morning, it was considered very auspicious.

1. Mahavir Jayanti
In Jainism, Mahavir Jayanti, also known as Mahavir Janma Kalyanak, is the most important
religious holiday. It celebrates the birth of Mahavira, the last Tirthankara. On the Gregorian
calendar, the holiday occurs either in March or April.
He was born on the thirteenth day of the rising moon of Chaitra. The chronology accepted by all
Jains places Mahavir's birth in 599 BCE.
Mahavira was born into royalty as the son of King Siddhartha and Queen Trishala. During
pregnancy, Trishala was believed to have had a number of auspicious dreams, all signifying the
coming of a great leader. The exact number of dreams differs according to the school of
Jainism; Svetambaras generally believe that the actual number is fourteen while Digambaras
claim sixteen instead. Regardless, the astrologers that interpreted these dreams claimed that
the child would become either an emperor or a Tirthankar. It is said that when Trishala finally
gave birth to Mahavira, the god-king Indra bathed the newborn himself with celestial milk, a
ritual essentially marking him as a Tirthankar.
Just before Mahavir was born , His mother had sixteen dreams. Mahavir was born at four in the
morning, which is considered very auspicious in Jainism and Hinduism.
Her sixteen dreams were:
A white elephant
A lion
Goddess Lakshmi with two elephants at her side showering flowers
The moon lighting the universe with silvery beams
A pair of jumping fish
The radiant sun, a golden pitcher
A lake full of lotus flowers
A calm ocean of milk
A celestial palace
A throne of rubies and diamonds
A celestial king ruling the earth
A garland

didn't feel any pain associated with childbirth.
