Bangabda: Based on Sanatana Hindu calendar.

Bangabda: An Era Based On Sanatana Hindu Calendar.

Bangabda was introduced by Great Bengali (Gauda) King Shashanka upon Sanatana Hindu Calendar, not by Mughal King Akbar.

Avik Sengupta | HENB | Kolkata | April 13, 2020:: Sanatana texts describe units of Kala measurements, from microseconds to trillions of years. According to these texts, time is cyclic, which repeats itself forever. The cycle repeats itself and that’s the concept of Yugas.

Bharatiya Calendar is a set of various lunisolar calendar that are traditionally used in the Indian Subcontinent and South East Asia with regional variations for social and Sanatana religious purposes. They adopt a similar underlying concept for timekeeping with based on sidereal year  for solar cycle and adjustment of lunar cycles in every three years, however also differ in their relative emphasis to moon cycle or the sun cycle and the names of months and when they consider the New Year to start.

Of the various regional calendars, the most studied and known Sanatana calendars are the Shalivahana Shaka found in South India, Vikram Sambat (Bikrami) found in Nepal, North and Central regions of India, Tamil calendar used in Tamil Nadu, and the Bengali calendar used in the Bengal – all of which emphasize the lunar cycle.

Their new year starts in spring. In contrast, in regions such as Kerala, the solar cycle is emphasized and this is called the Malayalam Calendar, their New Year starts in autumn, and these have origins in the second half of the 1st millennium CE. A Sanatana calendar is sometimes referred to as Panchanga (पञ्चाङ्ग). This is the real essence of Unity in Diversity of entire Aryavarta or Bharatbarsha; erstwhile Navibarsha the land of the supreme race of humans who went into the granular details of time to the highest ever dimension of the same . They worshipped a deity Yama who ruled over the life and death, as well as used to be a unit of Time. And their supreme deity is Kalantaka Mahadev, who is destroyer of kala(time).

The ancient Sanatana calendar conceptual design is also found in the Jewish calendar, but different from the Gregorian calendar. Unlike Gregorian calendar which adds additional days to lunar month to adjust for the mismatch between twelve lunar cycles (354 lunar days) and nearly 365 solar days, the Sanatana calendar maintains the integrity of the lunar month, but insert an extra full month by complex rules, every few years, to ensure that the festivals and crop-related rituals fall in the appropriate season.

Bengali calendar is also a luni-solar calendar and is aligned to the Sanatana calendar system. Sanatanas developed a calendar system in ancient times. Jyotisha, one of the six ancient Vedangas was the Vedic era field of tracking and predicting the movements of astronomical bodies in order to keep time. The ancient Indian culture developed a sophisticated time keeping methodology and calendars for Vedic rituals.

Surya Siddhanta is an important treatise on the concept of time and Bengali calender. The current Bengali calendar in use by Bengali people in the Indian states such as West Bengal, Tripura, Assam and Jharkhand is based on the Sanskrit text Surya Siddhanta. It retains the historic Sanskrit names of the months, with the first month as Baishakh. Their calendar remains tied to the Sanatana calendar system and is used to set the various Bengali Sanatana festivals.

 In rural Bengali communities of India, the Bengali calendar is credited to Vikramaditya, like many other parts of India and Nepal. However, unlike these regions where it starts in 57 BC, the Bengali calendar starts from 594 suggesting that the starting reference year was adjusted at some point.

Some historians attribute the Bengali calendar to the 7th century King Shashanka. The term Bangabda (Bengali Era) is found too in two Shiva temples many centuries older than Akbar’s reign, suggesting that a Bengali calendar existed long before Akbar’s time. Nitish Sen Gupta in his book, “The Land Of Two Rivers” mentioned about two terracotta temples of Bengal; one is in Dihargram of Bankura District and in Sonatapan; both are more than 1000 years old and these are the temples which are carrying the legacy of Bangabda. Researchers Meghna Guha Thakurta, Kunal Chakraborty et al also carry the same opinion that Bangabda is in existence much before Akbar.

    The beauty of Bharat lies in its past. The present day Bharat is full
    of violence and lack of knowledge. Since the cruel/brutal and barbaric
    foreign invaders came into India the progression came on hold. An
    exception is made by ISRO Gurus, who have shows Bharat NATIVE
    knowledge and beauty is not buried by the barbaric foreign killer Gods.
    Even in the corona virus crisis, Medical Gurus are serving Bharat on the
    best way. To keep the progression going India needs a NEW EDUCATIONAL
    SYSTEM under leadership of the VED-GURUS. The beauty of a country
    lies in its creation of knowledge under its DIVINE RULE, RAM RAJYA or
    GURU RAJYA. Bharat uphold your HINDU RASHTRAM! This is a message
    of Sri Hanuman Seva Sena.

    A grossly wrong historical narrative is this that Muslims ruled present day India for 800 years! The fact is hardly 500 years or so. They started roughly in 1200 CE after the second battle of Tarain. They consolidated in the northern by 1250 CE. Their end started in 1707 AD when Aurangjeb died. By 1757, the battle of Plassey was the last nail in the coffin of Muslims in the northern era. Even with most liberal views, their rule in northern India was from 1200 CE to 1750 CE or 550 years. But in the other parts of the country, it was much less. In telangana, Maharashtra, Gujarat and Central India, they started in 1300 CE and lost to the Marathas by 1730, a rule for 430 years. Odisha, Andhra, Karnataka for only 160 years 1560 tp 1720 and Tamil Nadu, and Kerala Assam for less than 150 years or so. If you take the average, it will be around 300 to 400 years.

    I draw the attention of the researcher Mr. Abhik Sengupto to look into the treatise of the great jyotish Shri Pathani Smanta of Odisha. It is a unique text which has formulated panchang for future 10000 yrs. One who is a real researcher can not afford to ignore it.

    Our history of Bengal was possibly rightly tried with Nihar Ray as we used to find in our Santiniketan school days 1957-67 , having moved across Bharat since 1967 living almost 64 destination for an unbiased identity , building projects but searching Indian history study as Itihas Parichay initiated by Tagore, later gone through Romilla and abridged version of Toynbee , then since 2012 after retirement going through RMIC Golpark enriched me such search feels beyond Christian Goggles we must search our identity if not beyond only few hundred years of Islam, with 23 Tirthankars in view pre Buddha since long.
