Makara Sankranti or Maghi, is a festival day in the Hindu calendar, dedicated to the deity Surya (sun). It is observed each year in the lunar month of Magha which corresponds with the month of January as per the Gregorian calendar and is a day the people of India and Nepal celebrate their harvest. It marks the first day of the sun's transit into Makara rashi (Capricorn), marking the end of the month with the winter solstice and the start of longer days.
