Kali Puja: Significance, Date and Observance

Kali Puja (काली पूजा) is observed on Kartik Amavasya, with worship performed at midnight. The deity honoured is Kali, and the central observance is night worship of Kali. It is kept widely in West Bengal, Odisha and Assam. This page sets out why the festival is kept, how its date is fixed from the panchang, and how it is observed across regions.

Significance and story

Kali Puja falls on the new moon of Kartik. The night is dark and the worship is at its darkest hour — this is not incidental to the festival but the shape of it. Where many festivals are timed to sunrise or to the bright half of the month, Kali Puja is deliberately placed at the junction of the lunar month's end, and the puja is held at midnight rather than at dawn or dusk.

The worship is directed to Kali, and the observance is described simply as night worship. Devotees keep vigil, and the rites are performed in the night hours rather than in daylight. Because the tithi is Amavasya — the last tithi of the waning fortnight — the day carries the character of an ending and a turning: the lunar cycle closes, and the next fortnight begins from it.

Readers looking for the fuller narrative associated with the deity will find it treated in the Puranic and Shakta literature. On this page we keep to what the panchang and the observance itself tell us: the tithi, the hour, the deity, and the regions where the festival is kept.

How the date is fixed

Kali Puja is fixed by tithi, not by a fixed Gregorian date. Specifically, it is observed on Kartik Amavasya, and the puja is performed at midnight. Because the tithi is a lunar measurement, its correspondence with the civil calendar shifts from year to year. Exact Gregorian dates are computed each year from the panchang and listed on this page.

A tithi is not a full solar day. It is the time taken for the longitudinal distance between the Moon and the Sun to increase by twelve degrees. A tithi therefore begins and ends at moments that do not align with sunrise, and a festival assigned to a tithi may be kept on the civil day on which that tithi prevails at the relevant hour. For a midnight observance, the hour that matters is the midnight hour itself.

This is also why the date can differ between calendars. Hindu festival dates follow the tithi, nakshatra or solar ingress at a place, so they can shift by a day between cities, and between amanta and purnimanta reckonings of the lunar month. A tradition that counts the month from the new moon and one that counts it from the full moon will name the same sequence of days differently, and the festival's placement in the civil calendar can follow. Dates given here are for New Delhi sunrise with Lahiri ayanamsha; readers elsewhere may see a variation of a day, and should follow their local panchang.

Puja vidhi

The observance is, in its essentials, night worship of Kali on Kartik Amavasya. The puja is timed to midnight. Householders and community pandals alike keep the vigil through the night hours.

Beyond this, the specific sequence of rites — the sankalpa, the upacharas, the offerings, the mantra and the conclusion — varies by family, by region and by the priest's tradition. Those details are properly taken from a qualified jyotishi or family purohit rather than generalised here. Where a household has an inherited paddhati, that is the one to follow.

Regional variations

Kali Puja is kept in West Bengal, Odisha and Assam. In these regions the festival is a major observance, and the midnight hour of Kartik Amavasya is the fixed point around which the night is arranged.

Practice outside these regions, and the precise ritual order within them, differs by community and by lineage. Where traditions differ — between regions, between amanta and purnimanta reckonings, and between household and community observance — we note the difference rather than settling on one form as authoritative. A reader in one city and a reader in another may keep the same tithi on adjacent civil days, and both are following their own panchang correctly.

What to avoid

• Do not treat the date as fixed in the Gregorian calendar. It is determined by Kartik Amavasya and computed each year from the panchang.
• Do not assume a single date applies everywhere. Tithi-based dates can shift by a day between cities and between amanta and purnimanta reckonings.
• Do not rely on this page for your local muhurat. The dates listed here are for New Delhi sunrise with Lahiri ayanamsha.
• Do not expect this page to prescribe outcomes. It describes the tithi, the deity and the observance; it makes no claims about results for any individual.
• For matters concerning your own chart, consult a qualified jyotishi.
