Buddha Purnima is celebrated by the followers of Gautam Buddha to commemorate his birthday. This year, the auspicious day falls on April 30. Generally, this festival is observed on the day of full moon in the Hindu month of Vaisakha. People in Lumbini celebrate the day on a large scale as it is believed that Buddha was born on this day in Lumbini (now known as Nepal) approximately around the year 563 BCE, as per Theravada Tripitaka. While this day is widely known to be the day when Buddha was born, many also believe that he attained salvation or Nirvana under the Mahabodhi tree at Bodh Gaya on this day.
