Come January, the skies will be filled with colourful, varied-paper kites of all sizes in preparation for the harvest festival of makar sankranti. The festival officially heralds the spring season's arrival and is the equinox's time. It is perhaps one of the few Indian festivals celebrated as per the Gregorian calendar. Makar sankranti is also known as lohri and maghi in north India, uttarayani in Uttarakhand, shishur saenkraat in Kashmir, khichdi parv in Uttar Pradesh, pongal in Tamil Nadu, makara sankramana in Karnataka, bhogali bihu in Assam, poush sankranti in West Bengal, and uttarayan in Gujarat, and Maharashtra.
