Bhoot Chaturdashi: Bengal's Night of 14 Lamps and 14 Greens

Bhoot Chaturdashi: Bengal's Night of 14 Lamps and 14 Greens

Bhoot Chaturdashi is the Bengali observance held on the 14th lunar day of the waning moon just before Kali Puja, when households eat chouddo shaak (14 leafy greens) and light chouddo prodip (14 lamps) after dark for 14 generations of ancestors. By the Bisuddha Siddhanta panjika it falls on Saturday 7 November 2026 and Thursday 28 October 2027.

If you plan to greet a friend abroad on both nights, two SubhSandesh numbers matter: 48.3% of shared pages are opened on a phone, and in our Raksha Bandhan 2026 sample (a different festival, n = 89) 49.4% of pages were built on the festival day itself. Below: the 2026 and 2027 dates and why calendars disagree, all 14 greens by name, the lamps and the stories behind them, and a fair comparison with Halloween.

What is Bhoot Chaturdashi, and what does the name mean?

Bhoot Chaturdashi is a Bengali Hindu night for the family dead, kept on the Chaturdashi (fourteenth tithi) of the dark fortnight of Ashwin by the amanta lunar reckoning, which Bengal's solar calendar places in Kartik. Elsewhere in India the same lunar day is called Naraka Chaturdashi or Kali Chaudas, but Bengali homes in West Bengal and Bangladesh keep it as a night to feed, light and protect the house.

Its two observances are domestic: a dish of mixed greens and 14 earthen lamps in the darkest corners of the home. There is no costume, no procession and no door-to-door visiting; the big public festival is Kali Puja, which follows.

The name also belongs to a 2019 Bengali horror film. A 2025 review in the Bengal Journal of Psychiatry criticises that film for conflating psychosis and delusional beliefs with supernatural possession; it is a separate thing from the observance.

When is Bhoot Chaturdashi in 2026 and 2027?

Bengali households follow a printed almanac, and these dates come from one of them. According to the Bisuddha Siddhanta panjika dates published by MyAstrology, Bhoot Chaturdashi falls on a Saturday in 2026 and a Thursday in 2027:

• 2026: Saturday 7 November. The Chaturdashi tithi runs from 10:49 am on 7 November to 11:29 am on 8 November, Kolkata time, and Kali Puja follows on Sunday 8 November.
• 2027: Thursday 28 October, the same calendar date as Kali Puja that year.

Measured against Halloween, that is exactly one week after 31 October in 2026 and three days before it in 2027. A family using a different panjika should go by its own.

The surprise is the mismatch with Naraka Chaturdashi. Drik Panchang's Kolkata Diwali calendar lists Kali Chaudas on 7 November 2026 but Narak Chaturdashi on 8 November. The Bengali Wikipedia entry cited below explains why: the Naraka Chaturdashi oil bath is taken before sunrise while the tithi is still running.

The timings show the split. In 2026 the tithi covers the afternoon and evening of 7 November, when greens are eaten and lamps lit, but only the dawn of 8 November. For 2027 the same Kolkata calendar puts Narak Chaturdashi and Kali Puja together on 28 October, so all three fall on one date.

Chouddo prodip: why 14 lamps, and for whom?

The 14 lamps are for ancestors. The Bengali Wikipedia entry on Bhoot Chaturdashi records the belief that 14 forebears of a family come to visit their living relatives that night, and that the lamps guide them home while chasing off spirits that mean harm.

Two other stories run alongside it in the same entry. In one, Kali comes in her Chamunda form with 14 ghosts to drive harm out of a devotee's home; in the other, the demon king Bali returns from the underworld the night before Kali Puja with a crowd of ghosts and spirits. Neither is a single official account, and families tell whichever one they grew up with.

The ghosts themselves have a long written record in English. Lal Behari Day's Folk-Tales of Bengal, whose preface is dated 27 February 1883, gathers the stories old women told little children in the evenings; four of its 22 titles are ghost stories. Its footnotes describe a Sankchinni as a pale female ghost who stands at the foot of a tree at night like a sheet of white cloth, and a Brahmadaitya as the ghost of a Brahman who died unmarried.

Chouddo shaak: the 14 greens, by name

The Bengali Wikipedia entry lists the classic 14 and traces the rule to Raghunandana Bhattacharya, the 16th-century Bengali smriti scholar, who recorded it in his Krityatattva. We have not read the Sanskrit text itself, so treat the attribution as the entry's. The list, in Bengali names with glosses where we could verify the plant:

1. Ol (elephant-foot yam)
2. Keu
3. Betho (bathua, lamb's quarters, Chenopodium album)
4. Kalkasunde (Senna sophera)
5. Neem (Azadirachta indica)
6. Sorshe (mustard greens)
7. Shalincha
8. Jayanti
9. Gulancha (Tinospora cordifolia)
10. Palta (pointed-gourd leaves)
11. Ghetu
12. Hinche (Enydra fluctuans)
13. Shushni (a Marsilea water clover)
14. Shelu

Names for keu, shalincha, jayanti, ghetu and shelu vary by district, so we left them unglossed. The same entry says Ashwin and Kartik were once called the season of Yama's fangs because illness peaked as the weather turned, and that the 14 greens were eaten to strengthen the body against it.

There is a harder reason these plants were on hand at that time of year. A 2014 survey of 167 households in Lalmonirhat and Nilphamari, northern Bangladesh, published in Evidence-Based Complementary and Alternative Medicine, recorded 34 non-conventional plant species people eat during Monga, the hunger season before the rice harvest. The greater Monga falls in the Bangla months of Ashwin and Kartik, mid-September to mid-November, which are the same weeks as Bhoot Chaturdashi.

Bathua, hinche and a Marsilea water clover appear on that famine-food list and on the chouddo shaak list. The overlap is our observation, not the study's claim, and the paper never mentions the festival. It records traditional medicinal uses rather than clinical results, so the immunity idea remains a belief, not a finding.

Bhoot Chaturdashi and Halloween: alike, not the same

People abroad often meet this night as "Bengal Halloween". The comparison helps for five minutes and misleads after that, so here they are side by side on five points.

The takeaway: both nights use light against the dark and both are crowded with ghosts, but Bhoot Chaturdashi is an obligation to named kin while Halloween is a public game. Calling it "Indian Halloween" quietly removes the ancestors, who are the whole point.

One message for Halloween, one for Bhoot Chaturdashi

With a close friend in Toronto or London, the calendar hands you a pair. In 2026 the nights are seven days apart, which suits a playful message on 31 October and a quieter one on 7 November; in 2027 Bhoot Chaturdashi comes first. Four lines written for that pairing, yours to copy:

• "You carve the pumpkin on the 31st; I light the fourteen lamps on the 7th. Same dark, two kinds of light."
• "Your ghosts want sweets. Mine only want the house swept and every corner lit. Happy Halloween, and a quiet Bhoot Chaturdashi."
• "Happy Halloween from half a planet away. Next week my mother counts out fourteen kinds of greens, and I will be thinking of you."
• "This year my ghost night comes before yours. Light something for the people you miss."

For the 31 October half, the interactive Halloween card suits a short, playful hello: up to six photos, a pumpkin they carve until your word glows, a letter read by flashlight, and about five minutes to make. If the friendship deserves more, the premium Halloween page with a voice note adds a recording of up to 60 seconds, up to 12 photos and an optional unlock time that shows only a countdown until the moment you set; it takes about ten minutes.

Both have a best-friend mode, so the closing question is not a romantic one. For 7 November a Halloween page is the wrong tone, and a radio-style dedication in your own voice fits a night about remembering better: they tune through static, land on your station and hear you introduce a song.

On timing, our only festival measurement is from Raksha Bandhan 2026, a one-day festival with n = 89 pages, too small for finer cuts. There, 49.4% of pages were built on the day itself and 27.0% the day before, so most people make these late. With a friend several hours behind you, build it a day early.

When a Halloween greeting is the wrong call

A greeting page is not always the right gesture on a night for the dead. Four cases stand out:

• A family in mourning. Bhoot Chaturdashi is about their dead. In the first year after a loss, a cute "Will you be my boo?" page lands badly; a phone call is better.
• An elder who reads Bengali first. Both Halloween templates have an English interface, and 48.3% of SubhSandesh views happen on a phone, so a small English screen is the likely experience.
• Someone in the same city. If you can walk over and help light the 14 lamps, do that instead.
• A group. These are one-person greeting pages, not party invitations.

If your note mentions grandparents who have died, add a password. Across the platform, 38.5% of SubhSandesh creators already put one on before sharing.
