The story
Saṅkrānti is the Sun's passage from one sign into the next. Of the twelve in a year this is the one India keeps, because it opens Uttarāyaṇa, the Sun's northward run and the lengthening of days. Bhīṣma, wounded on the battlefield of Kurukṣetra, lay on a bed of arrows for weeks waiting for this turn before he let go of life, since a death in Uttarāyaṇa carries no return.
The same day is Pongal in Tamil Nadu, Māgh Bihu in Assam, Uttarāyaṇ in Gujarat, Pedda Paṇḍuga in Andhra, Māghī after Lohṛī in Punjab, Pouṣ Saṅkrānti in Bengal, Khicaṛī in the Hindi belt, and Māghe Saṅkrānti in Nepal. Every region has its own harvest to give thanks for.
