Cultural significance


In India, the day of Sun entering the zodiacal belt Capricorn is celebrated as Makara Sankranti festival. Tropic of Capricorn is called Makara Vrutta in Indian languages. It should be noted here that the Indian astronomical calendar is not based on the Western sidereal system but has a differential lag. Hence, the festival is celebrated on either of 14th Jan or 15th Jan every year, when, as per the Indian astronomical calendar, the Sun enters the Capricorn sign.
