Based on the historical and chronological accounts of Sri Lankan historical texts Deepavansa and Mahavamsa, Shakyamuni Buddha was born in Lumbini in 623 BC on the day of Baisakh Purnima. Based on the reign of Emperor Ashoka and archeological facts, most of the historians believe that Buddha's birth date was 563 BC. While the United Nations and UNESCO internationally recognize Lumbini, the birthplace of Buddha, 623 BC is considered the birth date of Shakyamuni Buddha. The government of Nepal considers this date as Buddha's birth date.

Buddha passed away at the age of 80 in present-day Kushinagar, India, on the full moon day of Baisakh, an event known as Buddha's Mahaparinirvana. Counting from the time Buddha attained Mahaparinirvana, today falls on the 2569th Buddha Jayanti. Buddha died at the age of 35 in Bodh Gaya, India on the full moon day of Baisakh.

He attained enlightenment by destroying all his classes. It is certainly not a common occurrence for three major important events in a person's life (tri-samyoga) to fall on the same date. Thus, today is a day to remember these three events and to take inspiration to follow the path taught by the Buddha. 

In the context of celebrating Buddha Jayanti, since birth, enlightenment and Mahaparinirvana fall on the same date, the date of Buddha's Mahaparinirvana is considered as the basis for the joint memory of all three spiritual events. Buddhist countries such as India, Sri Lanka, Thailand, Myanmar, Cambodia, Laos, etc. seem to have taken this event as a celebration of his enlightenment, Mahaparinirvana and the Satyapath preached by him rather than the birth date of Buddha. With the rise of democracy in Nepal, especially after the renaissance of Theravada Buddhism, Buddha Jayanti has been celebrated based on Mahaparinirvana, inspired by the practices of these Buddhist countries. Generally, commemoration celebrations are based on the date of birth. In the context of celebrating Buddha Jayanti, it seems reasonable to celebrate Buddha's 2649th birthday today by calculating the time after his birth. Concerned stakeholders have also started raising their voices in this regard. Since Nepal is the birthplace of Buddha, it is necessary to start this work from our country. It is necessary to take high diplomatic initiatives from the state level to maintain unity in this regard among other Buddhist countries. 

Now some scholars interpret Buddha's teachings as a rebellion against the economic, social, religious and political system of the time. Even though the scholars have given this explanation because of the alternative and progressive ideology presented in the system at that time, the Buddhist literatures have explained deep ethical-characteristic-karmic and cosmic principles regarding the origin of Buddhist men. According to this principle, a virtuous person who has resolved to become a Buddha in accordance with the worldly need to reveal eternal truth knowledge (dharma), which has been extinct for a long period of time, is born as a Bodhisattva after completing all the virtues (parami) necessary to become Samyak Sambodhi for an eternity and attains Samyak Sambodhi through his own efforts. As described in the Pali literature, Bodhisattva Siddhartha, who was born as Sumedha Rishi during the time of Dipankara Buddha and promised to become Buddha in the future, achieved Samyak Sambodhi by his own efforts after completing 10 Parami, 10 Upaparami and 10 Paramattha Parami in different births for 4 countless and 100,000 kalpas. Jataka stories describe 547 such previous births of the Buddha. For today's human consciousness, the subject of 'parapsychology' such as eternal pre-birth, reincarnation seems suspicious, but Buddhist psychology and 'Buddhist cosmology' have given a reasonable explanation in this regard. 

It is difficult to estimate how many Buddhas have come into the world to this day, but Pali literature mentions 28 human Buddhas. The teachings (dharma) imparted by all these Buddhas are the same because these teachings are not the individual thoughts of each Buddha, but rather the revelation of eternal eternal laws that have been lost. These teachings are interpreted in a way that common people can understand, everyone can experience for themselves, asu-fruitful, everyone is invited to come, see can be said, 

s are introspective and can be felt by every sane person. Every Buddha who explores and investigates these truths and brings them to light are great men born in Kalkakalpa. Such great men are called by terms like Bhagwan, Arhanta, Samyaksambuddha. 

Buddha's teachings for 45 years are preserved today in Tripitaka as 84 thousand sutras. These teachings contain essential precepts for every aspect of a person's daily life, from higher mental spiritual benefits. These teachings were successfully used in the political, economic and social environment of the Buddhist society, while their relevance is increasing in today's world environment. Since the mind and its discipline are the main aspects of Buddhist education, the relevance of Buddhist education is increasing day by day in every aspect of human life including today's education system, mental health, family harmony, politics and ethics, economy and business, environmental protection, international relations and peace.
