[1] In Vedic texts, the Vrscika month is called Urja (IAST: Ūrja), with which a female goddess is also associated called Urja but in these ancient texts it has no zodiacal associations.
[1] The ancient and medieval era Sanskrit texts of India vary in their calculations about the duration of Vrschika, just like they do with other months.
For example, the Surya Siddhanta calculates the duration of Vrschika to be 29 days, 11 hours, 46 minutes and 0 seconds.
[5] In contrast, the Arya Siddhanta calculates the duration of the Vrschika month to be 29 days, 12 hours, 12 minutes and 24 seconds.
[5] The Indian solar month names are significant in epigraphical studies of South Asia.
