Why does Makar Sankranti fall on almost the same date every year, while most Indian festivals keep shifting? And if Uttarayan actually begins in December, why do we celebrate it in mid January? This episode breaks a very common assumption about the Indian calendar and reveals the elegant astronomical logic behind Sankranti.We explore what Sankranti really means, why there are 12 of them every year, and why only Makar Sankranti became culturally significant. From zodiac transitions and solar calendars to leap years and Earth’s slow cosmic wobble, this story connects ancient Indian astronomy with modern science in a surprisingly simple way.If you’ve ever wondered why Sankranti is sometimes on the 14th and sometimes on the 15th, or how calendars, equinoxes, and traditions like Uttarayan fit together, this episode will completely change how you look at Indian festivals and time itself.
