Scientifically, in the northern hemisphere, Sun's transition from Sagittarius to Capricorn takes place during the winter solstice. Henceforth Sun resumes its journeys northward. This is known as Makar sakranti. The days gradually become lengthier.
In West Bengal we celebrate the festival with rice-cakes (different kind of PITHE-PULI) and here we call it POUSH-SANKRANTI.
In Karnataka, women go to their friends' & relatives' homes and exchange Sesame and Joggery(Ellu-Bella) with them. Sesame is bitter and joggery is sweet. So, it is exchanged to indicate that happiness and sadness both are natural in life and one has to accept them equally. We also make pongal (which is called Akki Huggi in Kannada).
So, like this we celebrate this festival.
Happy Makar Sankranti to all.
In many villages across the state alpona is made in front of their houses. Alpona is similar to rangoli but in it the entire design is made using rice paste.
In many tribal villages they have festivals for three days during which they all get together and celebrate it in a big way.
Many fairs are also held on this day and the main attraction as already mentioned is Pithe-Puli.
