The concept of Saptha Rishis is known to Hindus.
These are the seven Sages who are to be accorded the highest respect and their works are believed to be the most authentic for the Manvanthara, a Time Scale to Indian Philosophy.
In performing any Hindu rite the mention of the Saptha Rishis is mandatory.
They are the Patriarchs of the Vedic Religion.
For the present Manvantara, the list is,
Atri, Bhrigu, Kuthsa,Vasishta,Gauthama,Gauthama Angirasa.
There is a variation of this as well,
Bhrigu, Atri, Angirasa Vashista, Pulastya, Pulalaha and Kratu.
Sanatana Dharma states that these Rishis change for each Manvanthara.
Manvantara is the astronomical time within an aeon or Kalpa, a “day (day only) of Brahma”, like the present Śveta Vārāha Kalpa, where again 14Manvantaras add up to create one Kalpa.

* there is a differnce in the name of the Rishis for the present Manvantara.
Hindu scriptures declare that the Saptha Rishis change as well as The Pole Star, The Dhruva Nakshatra.
This is validated by Modern Atronomy.
Lord Krishna in The Bhagavad Gita says.
‘I am Arjuna among Pandava and Abhijit among Nakshatras’.
Abhijit is the unseen Nakshatra in Hinduism , the twenty-eighth.
Abhijit is the Sanskrit name for Vega, the brightest star in the northern constellation of Lyra.
Abhijit means “Victorious” or “the One who cannot be defeated”.
This also changes for Manvantaras.
“Once Pluto moved into 10 degrees of Capricorn, it came within orb of Vega, another of astrology’s famous fixed stars.
Vega is one of the brightest stars in the sky – the 5th brightest in the whole of the sky. Back around 12,000 BCE, it was Earth’s pole star. And such cycles being what they are, it will be Earth’s pole star yet again – just prior to the year 14,000 CE…
“from an Earthly ‘pole pointer perspective’ means Planet Earth is currently pointed almost as ‘away’ from Vega as Earth will ever get. If a planet can ‘look away’ from something, Earth has another 800+ years to go, and it will be ‘pointed’ in as opposite a direction as it can get from Vega. And that’s a rather interesting notion, considering that the astrological Vega is known to be a charismatic position.”
It may be noted that Vasishta was the Kula Guru of Dasaratha and Lord Rama and Ram’s date is around 5000 BC.
