Every year on the 14th of January, Makar Sankranti is observed. Unlike most Hindu festivals, which are based on the Lunar Calendar and are determined by the changing positions of the Moon, Makar Sankranti is based on the Solar Calendar. Makar Sankranti is observed every year to commemorate the Sun's passage through the Capricorn or Makar sign. Sankranti simply translates to 'movement.' As a result, the event commemorates the Sun's entry into the Makar zodiac.

The duration of the day and night are equal on the day of the Makar Sankranti festival, making it one of the oldest solstice festivities. The festival formally heralds the arrival of spring, often known as Indian summer. The Sun stays in for a bit longer after this day than it did the previous days, making days last a little longer than nights.
