The tropical year (365.2422 days) vs. Gregorian year (365.2425 days) creates a tiny mismatch, corrected every four years by leap day. But Pongal doesn’t care about February 29 – it cares about the actual Earth-Sun geometry. Section 2: The Astronomical Anchor – Why This Date Matters Pongal marks the end of the winter solstice effect. On December 21/22, the sun reaches its southernmost point (Tropic of Capricorn). For three weeks, the sun appears to "stand still" – then, around January 14, it begins its northward journey ( Uttarayana – "the northern course"). when is pongal
