Vṛṣabha

[1] The ancient and medieval era Sanskrit texts of India vary in their calculations about the duration of Vrsabha, just like they do with other months.

For example, the Surya Siddhanta calculates the duration of Vrsabha to be 31 days, 10 hours, 5 minutes and 12 seconds.

In contrast, the Arya Siddhanta calculates the duration of Vrsabha to be 31 days, 9 hours, 37 minutes and 36 seconds.

[6] The Indian solar month names are significant in epigraphical studies of South Asia.

[7] Vṛṣabha is also an astrological sign in Indian horoscope systems, corresponding to Taurus.
