Dhanu (month) followed by the solar month of Makara. The Dhanus month is called "Margali" in the Tamil Hindu calendar. The ancient and medieval era Sanskrit texts of India vary in their calculations about the duration of Dhanus, just like they do with other months. For example, the "Surya Siddhanta" calculates the duration of Vrschika to be 29 days, 7 hours, 37 minutes and 36 seconds. In contrast, the "Arya Siddhanta" calculates the duration of the Vrschika month to be 29 days, 8 hours, 24 minutes and 48 seconds. Dhanu is also an astrological sign in Indian horoscope systems, corresponding to Sagittarius
