Kumbha is also an astrological sign in Indian horoscope systems, corresponding to Aquarius (astrology). Kumbha (month) Kumbha is a month in Indian solar calendar. It corresponds to the zodiacal sign of Aquarius, and overlaps with about the second half of February and about the first half of March in the Gregorian calendar. In Vedic texts, the Kumbha month is called Tapas (IAST: Tapas), but in these ancient texts it has no zodiacal associations. The solar month of Kumbha overlaps with its lunar
Lunar month the Northern Celestial Hemisphere, and the "descending node", where the Moon moves into the Southern. The draconic or nodical month is the average interval between two successive transits of the Moon through the same node. Because of the torque exerted by the Sun's gravity on the angular momentum of the Earth–Moon system, the plane of the Moon's orbit gradually rotates westward, which means the nodes gradually rotate around Earth. As a result, the time it takes the Moon to return to the same node is shorter than a sidereal month, lasting days (27 d 5 h 5 min 35.8 s).
