Amavasya – The New Moon Day in Hinduism, Explained
अमावस्या
What is Amavasya and when does it happen?
Amavasya is the no-moon (new moon) night that closes each lunar fortnight in the Hindu calendar, arriving about once every 29 to 30 days. It is treated as a quiet, inward day, held to be the most powerful time of the month for honouring ancestors through Pitru Tarpana and Shraddha, and for personal spiritual practice. New ventures and big celebrations are usually avoided; the day belongs to remembrance, charity and prayer.
Amavasya is the dark, moonless night that ends every lunar fortnight in the Hindu calendar, coming round roughly once a month. With the moon hidden, tradition reads the day as turned inward – a time to look back rather than forward. It is the classic day for remembering the departed through tarpan and shraddha, for bathing in sacred rivers, for quiet fasting and japa, and for giving in charity. Many Amavasyas carry their own names and meaning depending on the weekday or the month in which they fall, from the silent bath of Mauni Amavasya to the lamps of Diwali.
When Is Amavasya? The Monthly Rhythm
Amavasya is not a single dated festival – it returns roughly once a month, once for every lunar cycle, so there are twelve or thirteen Amavasyas in a year. Because it follows the moon and not the Western calendar, its Gregorian date shifts each month.
| Named Amavasya | Falls in | Next date | Why it matters |
|---|---|---|---|
| Mauni Amavasya | Magha (Jan-Feb) | 6 February 2027 | Silent holy bath at Prayag; a peak day of the Magh Mela |
| Sarva Pitru / Mahalaya Amavasya | Bhadrapada (Sep-Oct) | 10 October 2026 | Closes Pitru Paksha; shraddha for all ancestors |
| Diwali / Kartik Amavasya | Kartik (Oct-Nov) | 8 November 2026 | Lakshmi Puja in the north; Kali Puja in Bengal |
| Somvati Amavasya | Any month, on a Monday | 9 November 2026 | New moon on a Monday; special for married women and peepal worship |
A no-moon night that falls on a Monday is called Somvati Amavasya and one that falls on a Tuesday is Bhaumvati Amavasya – the weekday, not a fixed date, gives these their name, so they recur only when the tithi and the weekday line up. Because the calendar is lunar, the same named Amavasya lands on a different Gregorian date every year.
Why Amavasya Matters
Amavasya is considered the most inward day of the lunar month – held to favour ancestor rites and spiritual practice, and to be a poor choice for launching anything new.
With no moonlight, the night carries a settled, reflective mood. Classical thought links the waning fortnight (Krishna Paksha) that ends on Amavasya with release and letting go, which is why the day is given over to the departed rather than to fresh beginnings.
It is also read as a potent day for sadhana. Fasting, silence, japa and meditation are thought to go deeper when the outward pull of the full moon is absent, so many practitioners reserve Amavasya for quiet, disciplined worship.
The ancestors' day
Amavasya is the standing monthly date for honouring the pitrs (forefathers). Offering water and til (sesame) as tarpan, and performing shraddha for a departed parent whose passing fell in the dark fortnight, is a duty many families keep every month.
A day to turn inward
The hidden moon is taken as a signal to look within. Rather than parties or purchases, the tradition points towards fasting, silence, charity and prayer – working on the self instead of the world outside.
Hold back new starts
Weddings, housewarmings, shop openings and other shubh beginnings are generally kept off Amavasya. The energy of the day is thought to suit completion and remembrance, not fresh undertakings, so muhurats are usually set for brighter tithis.
Who Is Worshipped on Amavasya
Amavasya is less about one deity and more about the pitrs (ancestors), though several gods are honoured depending on the day and the region.
The Pitrs (ancestors)
The forefathers are the central focus. Water, sesame and a simple food offering are made so that the departed are remembered and their line stays blessed. On Sarva Pitru Amavasya this widens to include every ancestor, named or forgotten.
Lord Shiva & the peepal tree
Monday belongs to Shiva, so a Somvati Amavasya draws Shiva worship. Married women circumambulate and water the peepal (Ashvattha) tree, which is held sacred, praying for the long life of their husbands and the wellbeing of the family.
Goddess Lakshmi & Kali
The Kartik Amavasya night is Diwali. Homes in much of India worship Goddess Lakshmi for prosperity, while Bengal, Assam and Odisha keep the same night as Kali Puja, honouring the fierce mother goddess.
Lord Shani (Saturn)
When Amavasya falls on a Saturday it is called Shani Amavasya, and Lord Shani is propitiated with oil, black sesame and charity to ease the effects of Saturn in one’s chart.
Key Practices of Amavasya, Step by Step
The exact observance varies by family and by which Amavasya it is, but a common shape runs from the morning bath to evening charity.
- Snan (holy bath). Rise early and bathe, ideally in a sacred river such as the Ganga, Yamuna or the Sangam; where that is not possible, a few drops of Ganga water added to the bath at home stand in for it.
- Pitru Tarpana. Face south, and offer water mixed with black sesame (til) and kusha grass to the ancestors, reciting their names or a simple prayer of remembrance.
- Shraddha or Pind Daan. Where a monthly or annual shraddha is due, prepare pind (rice balls) and food offerings for the pitrs, often through a priest, especially on Sarva Pitru Amavasya.
- Vrat (fast). Many keep a full or partial fast through the day, breaking it only after the evening rites; some observe silence (mauna) alongside, most strictly on Mauni Amavasya.
- Peepal worship. On Somvati Amavasya in particular, water the peepal tree, offer it a thread wound around the trunk, and light a lamp – a practice tied to marital wellbeing and to Shiva.
- Deep daan and puja. Light a lamp at dusk for the ancestors and the deities of the day; on Kartik Amavasya this becomes the full Lakshmi or Kali puja of Diwali.
- Daan (charity). Close the day by giving food, clothes, sesame, oil or money to the needy and to Brahmins – charity done on Amavasya is held to reach the ancestors and to lighten karmic burdens.
The Special Amavasyas, by Name
Certain Amavasyas stand out through the year, each shaped by its month or the weekday it lands on.
Mauni Amavasya (Magha)
Falling in the month of Magha, this is the great day of silent bathing. Pilgrims take a mauna vrat (vow of silence) and bathe at the Triveni Sangam in Prayagraj, where it is one of the principal snan dates of the Magh Mela and the Kumbh.
Somvati Amavasya (Monday)
A new moon that falls on a Monday. It is prized by married women, who fast, circle the peepal tree and pray for their husbands’ long life, and it is treated as an especially auspicious day for tarpan and Shiva worship.
Bhaumvati Amavasya (Tuesday)
Amavasya on a Tuesday, linked with Mangal (Mars) and Hanuman. It is observed to relieve Mangal dosha and debt-related troubles, with charity, Hanuman worship and ancestor offerings.
Sarva Pitru / Mahalaya Amavasya
The final day of Pitru Paksha, the fortnight of the ancestors. Shraddha is offered to every departed forebear, including those whose date of death is unknown, making it the most important pitru day of the year.
Diwali / Kartik Amavasya
The darkest night of Kartik becomes the brightest festival. Rows of lamps drive back the dark, homes worship Goddess Lakshmi for prosperity, and across Bengal and the east the same night is kept as Kali Puja.
Hariyali / Shravan Amavasya
The new moon of Shravan, in the green heart of the monsoon. Known as Hariyali Amavasya, it is a day for planting trees and honouring nature, marked with fairs, swings and greenery across north and western India.

Frequently Asked Questions
What is Amavasya?
Amavasya is the no-moon or new-moon night in the Hindu lunar calendar, the day that ends each dark fortnight (Krishna Paksha). It comes about once every 29 to 30 days, so there are twelve or thirteen Amavasyas in a year. Traditionally it is an inward day, most auspicious for honouring ancestors and for spiritual practice.
When does Amavasya occur?
Amavasya occurs roughly once a month, once for every full lunar cycle. Because it follows the moon rather than the Western calendar, its Gregorian date shifts each month, and the exact window is fixed by tithi and varies by city, so a local panchang gives the precise timing.
Why is Amavasya considered important?
Amavasya is considered the most powerful day of the month for ancestor rites and for sadhana. With the moon hidden, the day is read as inward and reflective, ideal for tarpan, shraddha, fasting, charity and prayer. It is generally avoided for auspicious new beginnings such as weddings or business openings.
What rituals are performed on Amavasya?
The main practices on Amavasya are a holy bath, Pitru Tarpana (offering water and black sesame to the ancestors), shraddha or pind daan where due, fasting, worship of the peepal tree, lighting a lamp at dusk, and charity to the needy. The exact rites vary by family and by which named Amavasya it is.
What is Mauni Amavasya?
Mauni Amavasya is the new-moon day in the month of Magha (January-February), observed with a vow of silence (mauna) and holy bathing. It is one of the most important snan dates at the Triveni Sangam in Prayagraj during the Magh Mela and Kumbh, and in 2027 it falls on 6 February.
What is Somvati Amavasya and why is it special?
Somvati Amavasya is an Amavasya that falls on a Monday, which happens only once or twice a year. It is especially auspicious for married women, who fast and circumambulate the sacred peepal tree praying for their husbands’ long life, and Monday’s link with Lord Shiva makes it a favoured day for worship and tarpan.
What is Sarva Pitru Amavasya?
Sarva Pitru Amavasya, also called Mahalaya Amavasya, is the last day of Pitru Paksha, the fortnight dedicated to the ancestors. On this day shraddha is offered to all departed forebears, including those whose date of death is unknown, making it the most significant ancestor-remembrance day of the year. In 2026 it falls on 10 October.
Why is Amavasya avoided for new beginnings?
Amavasya is avoided for new beginnings because its energy is traditionally read as inward and completing rather than expansive. The dark fortnight that ends on Amavasya is associated with release and remembrance, so weddings, housewarmings and business launches are usually scheduled for brighter, waxing tithis instead.
May the new-moon night bring you stillness and the blessings of those who came before you. Pitru devo bhava.
