Karka Sankranti
When it falls
The date shifts because it tracks the moon, not the Gregorian calendar.

Why Karka Sankranti Matters
A sankranti is the moment the Sun crosses from one zodiac sign into the next, and it is reckoned purely from the Sun's position along the ecliptic — not from the Moon or the lunar fortnight. Karka Sankranti is the entry into Cancer (Karka), the fourth sign, and it usually falls around mid-July. Because the date is fixed by the Sun's longitude, it stays close to the same calendar window each year, unlike the tithi-based festivals that shift more widely.
The deeper meaning of this particular sankranti is the turn it marks in the year. From here the Sun begins Dakshinayana — its apparent southward journey — which runs for the next six months until Makar Sankranti, when the northward Uttarayana begins again. In traditional reckoning Dakshinayana is treated as the more inward, contemplative half of the year, a season for restraint, devotion, and remembrance rather than for major auspicious undertakings.
Karka Sankranti also sits at the threshold of the monsoon and the start of Chaturmas, the four-month period that opens around this season and is kept by many as a span of simpler living, fasting, and study. The mood of the festival follows from this: it is observed quietly and with intent, not with the public celebration of a harvest day.
Rituals & observance
Karka Sankranti is observed in the hours around the Sun's ingress — the period known as the punya-kala (the meritorious window). The acts kept on this day are simple and personal rather than elaborate.
- Take a holy bath (snan) during the punya-kala, ideally in a river or sacred water; where that is not possible, a bath at home with the intention of the day is kept instead.
- Offer charity (dana) — food, grain, clothing, or money to those in need — which is considered especially meaningful on a sankranti.
- Make water and sesame offerings to ancestors (tarpan) where the family tradition includes remembrance of the departed on sankranti days.
- Observe a light or simple diet, and in households that keep Chaturmas, begin the period's vows of restraint and devotion from around this time.
- Spend part of the day in prayer, reading, or remembrance rather than in major new ventures, in keeping with the inward character of Dakshinayana.
