October (Roman month) did not number days of a month sequentially from the 1st through the last day. Instead, they counted back from the three fixed points of the month: the Nones (5th or 7th), the Ides (13th or 15th), and the Kalends (1st) of the following month. The Nones of October was the 7th, and the Ides was the 15th. The last day of October was the "pridie Kalendas Novembris," "day before the Kalends of November". Roman counting was inclusive; October 9 was "ante diem VII Idūs Octobris", "the 7th day before the Ides of October," usually abbreviated "a.d. VII Id. Oct."
Dhanu (month) (astrology). Dhanu (month) Dhanu, or Dhanus, is a month in the Hindu calendar, Malayalam calendar and others. It corresponds to the zodiacal sign of Sagittarius, and overlaps with approximately the second half of December and about the first half of January in the Gregorian calendar. In Vedic texts, the Dhanus month is called Sahas (IAST: Sahas), but in these ancient texts it has no zodiacal associations. The solar month of Dhanu overlaps with its lunar month Pausha, in Hindu lunisolar calendars. The Dhanu marks the winter season for the Indian subcontinent. It is preceded by the solar month of Vṛścik‌‌‌a,
