Makar Sankranti 2027: Why the Date Is Arguable

A solar festival, which is why its date barely moves

Almost every Hindu festival is lunar, anchored to a tithi, which is why Diwali and Holi roam across the Gregorian calendar by weeks. Makar Sankranti does not, and the reason is that it is solar.

Sankranti means the Sun's passage from one sign into the next. Makar Sankranti is the passage into Makara, Capricorn. There are twelve such transitions a year and this is the one that is celebrated nationally, under many names: Pongal, Magh Bihu, Uttarayan, Maghi, Khichdi.

Because it depends on the Sun alone, it lands on 14 or 15 January every year rather than wandering. The variation between those two dates is what this page is about.

The computed instant for 2027

Using the Lahiri ayanamsa, which is the Indian government standard, the Sun reaches zero degrees of sidereal Capricorn on **14 January 2027 at 20:56 IST**.

That figure is a straightforward computation and it is not controversial. Different ayanamsas shift it: a practitioner using Raman or Krishnamurti will get an instant some hours earlier or later, because those place the sidereal zero point differently. Within Lahiri, the number is the number.

What the number does not settle is which day to observe, because 20:56 is well after sunset, which in Delhi in mid-January is near 17:45.

Punya kaal, and why night entry moves the day

The observance is not the instant. It is the punya kaal, the meritorious period around the sankranti, during which bathing in a river, giving charity, and offering sesame and jaggery are prescribed.

Punya kaal is reckoned in daylight. The usual rules give a window of some hours following the sankranti moment, and a shorter maha punya kaal at its start. When the sankranti falls during the day, the punya kaal runs from that moment and the festival is observed the same day.

When the sankranti falls at night, there is no daylight left to contain it. The standard convention is then to shift the observance to the following sunrise and reckon the punya kaal from there. Applied to 2027, the entry at 20:56 on 14 January points the observance to the morning of 15 January.

That convention is widely used but it is a convention, not an astronomical fact, and some traditions and almanacs handle a night sankranti differently. So both dates will appear in print. Anyone telling you the other date is simply wrong is overstating what the tradition settles.

Why Sankranti drifted away from the solstice

Makar Sankranti is popularly described as the start of Uttarayana, the Sun's northward journey, which is the winter solstice. The solstice is near 21 December. The festival is near 14 January. The gap is about twenty four days and it is not an error.

It is precession. The sidereal zodiac is fixed to the stars; the tropical zodiac, and the solstice, are fixed to the seasons. The two drift apart by roughly one degree every seventy two years, and the accumulated difference is the ayanamsa, about 24.2 degrees now.

So when the sidereal Capricorn entry was computed in antiquity it did coincide with the solstice. Since then the solstice has stayed put seasonally while the sidereal entry has walked forward through the calendar at about a day every seventy two years. In another few centuries Makar Sankranti will fall in February.

This is the same drift that separates a Vedic chart from a Western one, and it is the clearest everyday illustration of it. Anyone who has been told their Western sun sign and their Vedic Moon sign do not match is looking at the same twenty four degrees.
