Amavasya 2027 List: Somvati, Bhaumavati, Shanishchari

The lunation table has thirteen new moons in 2027, and each Amavasya is current at exactly one New Delhi sunrise: thirteen Amavasya days, none doubled or lost. What changes from one to the next is the weekday, which gives three of them the name Somvati, two the name Bhaumavati and one the name Shanishchari; the afternoon, which is where the Dharmashastra manuals put the monthly offering to the ancestors; and, once, the city.

The 2027 List (अमावस्या 2027)

The date is the day whose sunrise falls inside the Amavasya. The month column gives the amanta name, used in Gujarat, Maharashtra and the south, then the purnimanta name north Indian calendars print, one month further on for a dark-fortnight tithi. The tithi ends at the new moon.

How the Days and Months Were Found

Each row starts from a new moon in the site’s DE421 lunation table, because the Amavasya always ends at that instant. Where a festival row covers the Amavasya its start is copied from it; for the other ten it comes from the site’s lunar code, which is never more than 1 minute out against the 86 tithi spans the festival tables print. The daily panchang then says which sunrise each Amavasya holds, checked in both directions, so a tithi that missed every dawn or covered two would have stopped the build.

The amanta month is named from the sidereal sign the Sun occupies at the new moon that opens the lunation: Sun in Sagittarius makes Pausha, in Capricorn Magha, and so on round the zodiac. No lunation of 2027 keeps the Sun in one sign at both its new moons, so no month is added, and the same count reproduces the month of all 43 dated rows in the 2027 festival table.

Somvati, Bhaumavati and Shanishchari: Names From the Weekday

North Indian calendars add a second name when the Amavasya day is one of three weekdays: Somvati for a Monday, the weekday of Chandra, the Moon; Bhaumavati for a Tuesday, the weekday of Mangal; and Shanishchari for a Saturday, the weekday of Shani. In 2027 the Mondays are 8 March, 2 August and 27 December; the Tuesdays are 6 April and 31 August; the one Saturday is 6 February, which is also the Amavasya that purnimanta calendars call Magha Amavasya.

The label is read off the sunrise day and records only a meeting of tithi and weekday; the page prints it so that a date can be found under the name a calendar uses, and reads nothing more into it. Because it rides on the sunrise, it moves when the sunrise reading moves, as it does in April.

The April Tuesday Depends on the City

The Phalguna Amavasya (amanta) begins at 05:41 on 6 April, only 25 minutes before the New Delhi sunrise of Tuesday 6 April. That start is a computed instant and the margin is under this page’s half-hour threshold, so the New Delhi call rests on the daily table, which reads the tithi at each sunrise from DE421: Monday dawns on Krishna Chaturdashi, Tuesday on Amavasya and Wednesday on Shukla Pratipada. In New Delhi, then, this is a Bhaumavati Amavasya.

Sunrise comes earlier further east, and the fixed start of the tithi then has less of a lead or none. In Mumbai and Ahmedabad, where the sun rises later, the Amavasya is more than half an hour old at the Tuesday sunrise; Chennai and Kolkata are too close to call; and in Guwahati the sun is up before the Amavasya begins, so its Tuesday dawns on Chaturdashi. The new moon at 05:21 on 7 April then lands within half an hour of the next sunrise in Kolkata and Guwahati, so whether a Wednesday Amavasya appears there is not something these minutes settle. The same table shows the Friday sunrise of 4 June, clear in New Delhi by 78 minutes but too close in Guwahati.

For any other town, the panchang calculator gives the local sunrise and the tithi it falls in.

Tarpan in the Afternoon, and Three Afternoons That Move

The Dharmashastra manuals attach a monthly offering to the ancestors, the darsha shraddha, to every Amavasya, and they set its tarpan in the aparahna, the afternoon. The site’s festival generator has a fixed test point for that part of the day, which it uses for Dussehra: the middle of the fourth of five equal parts of daylight. Tested at that point, eight Amavasyas hold the afternoon of their own sunrise day. Three times the Amavasya ends on the morning of its sunrise day, before that day’s afternoon, after covering the afternoon before: 3 July against 4 July, 29 September against 30 September and 27 November against 28 November. In March the earlier afternoon is clear and the Somvati one too close to call, and on 2 August, also a Monday, the afternoon test point and the new moon are within 27 minutes of each other. The page shows these as a second reading; which day a family offers tarpan is for its purohit and its own calendar.

Sarva Pitru Amavasya: Sunrise and Afternoon Disagree

The 2027 table puts Sarva Pitru Amavasya, the close of Pitru Paksha, on Thursday 30 September, by the sunrise rule. That Amavasya runs from 10:55 on 29 September and ends 113 minutes after the 30 September sunrise, so by that day’s afternoon the tithi is Shukla Pratipada, the first day of Sharad Navratri in the same table. The only afternoon the Amavasya covers is Wednesday 29 September. The festival row and the afternoon test name different days, and the page shows both.

Diwali Lands on the Sunrise Amavasya in 2027

Diwali is not decided by sunrise; its row tests the Amavasya at pradosh, the evening. In 2027 the two agree. On the evening of 28 October the Amavasya is still more than three hours away at sunset, and on Friday 29 October it is still running 88 minutes after sunset, the same day the sunrise reading gives. In 2026, by contrast, the pradosh rule puts Diwali on 8 November, a day before the sunrise Amavasya of 9 November. By the amanta reckoning this is Ashwina Amavasya; north Indian calendars call it Kartik Amavasya.

Paush, Mauni and Shani Jayanti

The year opens with the Amavasya of Thursday 7 January, which purnimanta calendars call Paush Amavasya and amanta ones Margashirsha Amavasya. The next, on Saturday 6 February, is the Magha Amavasya of the north, kept there as Mauni Amavasya, and the year’s only Shanishchari. Shani Jayanti has its own row on Friday 4 June, the Vaishakha Amavasya of the amanta calendar, and as a Friday it carries none of the three weekday names.

Other 2027 Lists

The full moons of the year, with their own sunrise-and-evening split, are in the Purnima 2027 list, and the bright and dark Ekadashis in the Ekadashi 2027 list. The Krishna Chaturdashi night that comes before each Amavasya is in Masik Shivratri 2027, and the last Amavasya of 2026 is worked through on the Margashirsha Amavasya 2026 page. Every Amavasya sunrise in the site’s tables is on the Amavasya tithi page; the festivals are on the festival pages and in the 2027 festival calendar. In Hindi: अमावस्या 2027 की सूची: सोमवती, भौमवती, शनिश्चरी.
