In Hindu culture, the names of the weekdays have been determined based on the ancient astronomical text called the Surya Siddhanta. This text, which was written in Sanskrit, describes the movements and characteristics of celestial bodies and provides information about the calculation of time.
According to the Surya Siddhanta, each day of the week is named after a celestial body. The seven celestial bodies used for this purpose are the Sun, Moon, Mars, Mercury, Jupiter, Venus, and Saturn. These seven celestial bodies were considered the most important and were believed to have a significant impact on life on Earth.
The first day of the week is dedicated to the Sun and is known as Ravivara. The Sun was considered to be the most important celestial body and was worshipped as a deity in Hinduism. The second day is dedicated to the Moon and is known as Somavara. The Moon was believed to influence tides and human emotions, and its waxing and waning phases were used to determine the phases of the lunar month.
The third day of the week is dedicated to Mars and is known as Mangalavara. Mars was believed to be associated with conflict and was considered to have a significant impact on human affairs. The fourth day is dedicated to Mercury and is known as Budhavara. Mercury was considered to be the planet of communication and was believed to influence commerce and trade.
The fifth day of the week is dedicated to Jupiter and is known as Guruvara. Jupiter was considered to be the planet of wisdom and was believed to influence growth and expansion. The sixth day is dedicated to Venus and is known as Shukravara. Venus was considered to be the planet of love and was believed to influence beauty and sensuality.
The final day of the week is dedicated to Saturn and is known as Shanivara. Saturn was considered to be the planet of restrictions and was believed to influence limitations and obstacles.
In conclusion, the names of the weekdays in Hindu culture were determined based on the movements and characteristics of celestial bodies as described in the Surya Siddhanta. This system of naming the days of the week has been in use for thousands of years and continues to be an important part of Hindu culture and tradition.
