Amavasya Dates 2026–2027 and Purnima Dates — Every Date With Its Timing

The lunar month has two halves and two hinge points. Purnima, the full moon, closes the bright half; amavasya, the new moon, closes the dark half. Between them they anchor almost every Hindu festival, which is why the amavasya dates 2027 and purnima dates 2027 are worth having in one place with their exact timings.

The table above gives both lists for whichever year you choose, with the minute each tithi begins and ends, the day of the week, and the festival that falls on it. Because the tithi rarely aligns with a calendar day, the observance is kept on the day it prevails at sunrise - and that day is what the table shows, computed for your own city rather than for a national average.

A normal year holds twelve of each. When an adhik maas is inserted there are thirteen, and the extra month repeats a name. The calculator handles that automatically.

Almost every purnima carries a festival, which is why the purnima vrat list doubles as a calendar of the year's major observances.

The vrat itself is simple: a partial fast until moonrise, Satyanarayan katha at home, a bath in a river where one is close, and charity. None of it is compulsory, and the scale varies enormously between families.

The sharad purnima date deserves separate mention. Falling in Ashwin, usually October, it is the night the Moon is held to be at its most complete and its rays most restorative. Kheer is left out in the moonlight overnight and eaten the next morning, and in many regions it also marks Kojagari Lakshmi Puja, when the goddess is said to ask who is awake.

The amavasya timing today, or for the next one if today is not an amavasya, sits in the card at the top of this page with the exact start and end of the tithi for your city. The full year's list follows in the table.

Amavasya is the day for ancestors. Tarpan - offering water with black sesame - is performed, charity is given, and where a river is accessible a bath is taken. Kali and Shani are worshipped on particular amavasyas. What the day is not used for is beginnings: no weddings, no griha pravesh, no new ventures.

Three amavasyas stand apart. Mauni Amavasya in Magha is the great bathing day of the Magh Mela, kept in silence. Sarva Pitru Amavasya in Ashwin closes Pitru Paksha and serves for every ancestor whose tithi is unknown. And the Kartik amavasya is Diwali itself - the one amavasya of the year that is celebrated rather than observed quietly.

When an amavasya falls on a Monday it becomes Somvati Amavasya, and the day carries far more weight than an ordinary new moon. Soma is the Moon, and Monday is the Moon's day; the coincidence of the Moon's own tithi with its own weekday is read as a doubling of its influence.

It comes irregularly - some years hold two or three, others none at all. The table above marks every somvati amavasya date in green for the year you choose, so it can be planned for in advance.

The observance belongs particularly to married women, who fast and circumambulate a peepal tree one hundred and eight times, tying a thread around it, for the long life of their husbands. Men and unmarried people observe it as an ordinary amavasya with tarpan and charity. In many families it is also the preferred day of the year for a pind daan at Gaya or a river bath.

Because it depends on a coincidence of tithi and weekday rather than on any fixed date, a somvati amavasya date cannot be predicted by eye - which is exactly what the computed table on this page is for.

1. Tithi boundaries. The Moon's elongation from the Sun is tracked through the year with the Swiss Ephemeris; the moments the fifteenth and thirtieth tithis begin and end are found to the minute.

2. The day of observance. The day on which the tithi prevails at your city's sunrise is selected, using your latitude and longitude.

3. Names and weekday. The lunar month gives each date its traditional name, and the weekday is checked so Somvati Amavasya can be flagged.

Between one amavasya and the next lies a full lunar month of about twenty-nine and a half days, divided at purnima into two halves. The bright half, shukla paksha, runs from the new moon to the full moon as the Moon waxes. The dark half, krishna paksha, runs from full to new as it wanes.

Almost every observance in the Hindu calendar is fixed by this rhythm rather than by a date. Ekadashi comes twice a month, once in each half. Sankashti Chaturthi falls in the dark half and Vinayaka Chaturthi in the bright. Pradosh comes twice. The two halves also carry different characters in the tradition: the waxing half is favoured for beginnings and growth, the waning half for completion, release and ancestor rites.

One regional difference is worth knowing because it causes genuine confusion. In north India the lunar month ends at purnima - the purnimanta system - while in the south and west it ends at amavasya, the amanta system. The dates are identical; only the month name attached to a dark-half tithi differs. A festival in Krishna paksha may therefore be called Shravana in Maharashtra and Bhadrapada in Uttar Pradesh on the very same day.

Every row in the tables above carries two times - when the tithi begins and when it ends - and knowing how to read them prevents most calendar arguments.

A tithi lasts anywhere from about nineteen to twenty-six hours, because the Moon's speed varies through its orbit. It therefore rarely matches a calendar day. The rule for observance is simple: the day on which the tithi is running at sunrise is the day it is kept. That is the day shown in the Date column here, already computed for your city.

Two edge cases follow from this. A tithi that begins after one sunrise and ends before the next touches no sunrise at all and is kshaya - skipped from the calendar. A tithi that covers two sunrises is vriddhi - it appears twice, and the observance is kept on the first or second depending on the specific rule for that festival.

For fasting that ends at moonrise - purnima vrat in particular - the end time matters as much as the date, which is why both are given. And for amavasya rites, the tarpan is performed while the tithi is actually running, not merely on the calendar day it falls.

The gap between what the texts prescribe and what households do is wide, and the practical version is worth recording.

On purnima, most families light a lamp, keep a light meal or a partial fast until moonrise, and read or hear the Satyanarayan katha - often on the nearest convenient evening rather than the exact day. Where a temple or river is close, a visit is made. On Sharad Purnima the kheer is put out overnight; on Kartik Purnima lamps go to the water.

On amavasya, the observance is quieter. Water with sesame is offered facing south, a meal or some money is given in charity, and nothing new is begun. Many families cook a simple meal the ancestors were fond of. Shani worship is added where the family keeps it, and on Diwali amavasya the day turns into the year's largest celebration instead.

Neither day requires a priest, a long ritual or expense. What the tradition asks for is attention on a fixed rhythm - twice a month, every month - and the calendar on this page exists mainly to make that rhythm easy to keep track of.
