Why is Capricorn season not Makar Sankranti?
Tropical Capricorn begins when the Sun’s longitude is 270 degrees. That is the solstice, 21 December 2026 at 20:50 UTC, and it ends when the Sun enters Aquarius on 20 January 2027 at 07:29 UTC. Sidereal Makar Sankranti, used for Pongal and Lohri, is observed on 15 January because that zodiac is measured from the stars, not from the solstice point.
The sign is a coordinate. Qhapaq Raymi is the Andean feast of the same solstice. The page does not turn the month into a personality.
