Makara Sankranti

Makar(a) Sankrānti (Sanskrit: मकरसङ्क्रान्ति, romanized: Makarasaṅkrānti; transl. Capricorn Festival) also referred to as Uttarāyana, Makara, or simply Sankrānti, is a Hindu observance and a mid-winter harvest festival in India and Nepal. The Sun God (Surya) is worshipped in Makar Sankranti. It is typically celebrated on 14 January annually (15 January on a leap year). This occasion marks the transition of the sun from the zodiac of Sagittarius (dhanu) to Capricorn (makara). As this transition coincides with the sun's movement from south to north, the festival is dedicated to the solar deity, Surya, and is observed to mark a new beginning. Across India, the occasion is celebrated with numerous multi-day festivals.
