Vaishakh Month 2027: Start and End Dates, Buddha Purnima

Vaishakh 2027 in Short (वैशाख मास)

Vaishakh (also written Vaishakha, Baisakh or Vaisakh) is the second month of the lunar year, and in 2027 it has two sets of edges depending on the almanac. North Indian purnimanta calendars, which run from the day after one full moon to the next full moon, open it on Wednesday 21 April and close it on Thursday 20 May, Buddha Purnima: 30 sunrises at New Delhi. Amanta calendars, kept in Maharashtra, Gujarat, Karnataka and the Telugu states, count from new moon to new moon; their Vaishakh starts on Friday 7 May and its last morning is Friday 4 June, 29 sunrises.

The two versions overlap for the bright fortnight only, 7 May to 20 May, which is 14 days long and carries Akshaya Tritiya, Mohini Ekadashi, Narasimha Jayanti and Buddha Purnima. The north’s dark half, 21 April to 6 May, is still Chaitra on an amanta calendar, and the amanta dark half, 21 May to 4 June, is already Jyeshtha in the north. That split is why the same Ekadashi or Amavasya can carry a Vaishakh label in one household almanac and a neighbouring month’s in another. The Chaitra month 2027 page covers the month before.

The Bengali Boishakh and the Punjabi Vaisakh are a separate, solar reckoning: the Sun’s stay in sidereal Aries. By the site’s ingress table that stay starts at 15:23 IST on 14 April 2027 and ends when the Sun reaches Taurus at 12:14 IST on 15 May 2027. Which civil day those calendars count as the first of their month, and the festivals kept on it, follow their own rules; this page gives the two instants and leaves the observance days to the regional almanacs.

The Four Lunations That Fix the Edges

Each boundary is an instant in the site’s DE421 lunation table. A civil day belongs to whichever tithi is running at its sunrise, so the table below sets each instant beside the first or last New Delhi morning it produces.

The April full moon comes at 03:57 on 21 April, 113 minutes ahead of sunrise, so that Wednesday already dawns on the Krishna Pratipada and opens the north’s Vaishakh. The morning before, Tuesday 20 April, is the Purnima of Chaitra and the festival table’s Hanuman Jayanti. The amanta month starts a fortnight later: the May new moon falls at 16:28 on 6 May, well into the afternoon, which leaves that day as the Amavasya closing amanta Chaitra and 7 May as the first Vaishakh sunrise. At the far end, the full moon of 20 May arrives at 16:29, so Buddha Purnima’s morning is still Purnima and is the north’s last day of the month. The June new moon lands at 01:10 on 5 June, hours before sunrise in any listed city, and 4 June is the last amanta morning.

On those edge mornings (21 April, 6 May, 7 May, 20 May, 21 May and 5 June) the town does not matter. The site’s sunrise code places every one of the 38 cities in its panchang list on the same tithi as New Delhi, each with at least half an hour to spare.

Kshaya and Vriddhi: Thirty Tithis, Not Thirty Days

A lunar month has thirty tithis, but they do not map one-to-one onto sunrises. In the north’s Vaishakh the Krishna Panchami is current at two sunrises in a row, 25 April and 26 April (a vriddhi tithi), and the Shukla Panchami is current at none (a kshaya tithi), which is how 30 sunrises carry thirty tithis. The amanta month shares the lost Panchami, doubles the Krishna Saptami on 27 May and 28 May, and drops the Krishna Chaturdashi as well, leaving 29 sunrises.

The two dropped tithis are not rows in the festival table, so their start and end instants below come from the site’s lunar code; checked against the generated tables, that code differs by at most 1 minute across 86 festival rows. The Shukla Panchami opens at 06:23 on Monday 10 May, 50 minutes after New Delhi’s sunrise, and ends at 03:48 on 11 May, before the next one. That opening is close enough to dawn for the west and south to matter:

Every listed city computes 10 May as Shukla Chaturthi and the following morning as Shukla Shashthi, so on the arithmetic the Panchami holds no sunrise anywhere. The closing side is comfortable in every town. The opening side is not: in 15 cities of the 38, every one of them in the west or the south of the country, sunrise on 10 May comes less than half an hour before the Panchami begins, and in Goa the gap is only 16 minutes. That is inside the half hour this site wants before ruling on a sunrise tithi. For a reader there, whether the dropped tithi of this fortnight is the Panchami or the Shukla Chaturthi before it is an almanac’s call, not this page’s. In Kolkata and Guwahati, where the Sun rises earlier, the margin is wide.

The Krishna Chaturdashi in the amanta dark half runs from 06:35 on 3 June to 04:05 on 4 June, opening after one sunrise and closing before the next, so 4 June dawns on the Amavasya. Here the risk sits in the east: Guwahati’s sunrise that morning, at 04:30, trails the start of the Amavasya by 25 minutes, the one city of the 38 under half an hour. Everywhere else the reading is clear. Your own town’s sunrise tithi is on the panchang calculator.

Festivals and Ekadashis in Each Version of Vaishakh

The timeline lists the dated events in order. Clock times appear only for instants carried in the site’s tables, and the two right-hand columns give the month each calendar assigns to that date’s New Delhi sunrise.

The north’s dark fortnight has one Ekadashi, on Sunday 2 May, a single sunrise. The Ekadashi 2027 list files it under Chaitra, because it names months the amanta way, and gives it the vrat-katha name Varuthini; a purnimanta almanac counts the same fast as Vaishakh Krishna Ekadashi. That fortnight ends with the Amavasya of Thursday 6 May, Vaishakh Amavasya in the north and Chaitra Amavasya in amanta calendars.

In the shared bright fortnight, Akshaya Tritiya is the festival table’s Saturday 8 May, decided by its rule “tithi at madhyahna”. The Tritiya runs from 11:43 on 8 May to 09:03 on 9 May: it is running at midday on 8 May and has ended before midday on 9 May, even though 9 May is the morning that dawns on the Tritiya. The Akshaya Tritiya 2027 page covers the tithi and the rule in detail; this page gives no time window for the day. Mohini Ekadashi follows on Sunday 16 May. Narasimha Jayanti is the table’s Tuesday 18 May, under the rule “tithi through sayahna kaal”: that morning dawns on the Shukla Trayodashi, and the Chaturdashi it is dated by opens at 16:04, before evening. The fortnight and the north’s month end on Buddha Purnima, Thursday 20 May in the festival table, the Purnima the site’s festival rules file as Vaishakha’s.

Only the amanta reader is still in Vaishakh after the full moon. That calendar’s dark-half Ekadashi, on Tuesday 1 June, is the one the Ekadashi list names Apara; the north files it under Jyeshtha. Amanta Vaishakh then closes on Friday 4 June with the Amavasya on which the festival table dates Shani Jayanti. The festival rules file that day as Vaishakha’s dark-half fifteenth, and their own note warns that north Indian sources name dark-fortnight festivals by the purnimanta month, which makes the same day Jyeshtha Amavasya there. The May 2027 vrat and festival list has the rest of the month’s observances.

The month’s name has a lunar source too. The naming scheme the Purnima 2027 list follows pairs Vaishakha with the nakshatra Vishakha; the lunation table puts the 20 May full moon in the next nakshatra, Anuradha, in Scorpio, while the daily table still has the Moon in Vishakha at that morning’s sunrise. Searches for Vaishakh snan dates have no answer here: the site’s tables do not carry the custom’s start or end rule, so this page does not date it.

The Sun in Aries and Taurus, and No Kharmas

The Sun reaches sidereal Aries on 14 April, six days before Hanuman Jayanti, and that ingress date is where the site’s Meena Kharmas ends. Both lunar Vaishakhs therefore open with the Sun in Aries, and the convention the site’s Amavasya 2027 list uses, naming an amanta month from the Sun’s sign at the new moon that opens it, gives Aries at the 6 May new moon and so Vaishakha. The move into Taurus comes at 12:14 IST on Saturday 15 May, inside both versions of the month, and it is the only solar ingress between the two amanta new moons; the site’s panchang data counts a lunation without one as adhika, and its 2027 table has none. The day on which the Taurus ingress is observed is left to the almanacs.

Neither Vaishakh contains any Kharmas day. The site’s Kharmas table has Meena Kharmas ending at the Aries ingress and the next stretch beginning on 16 December, and the muhurat engine’s 2027 closure list has nothing that touches 21 April to 4 June: its marriage calendar is open from 15 April to 5 July, the eve of the Shukra asta closure. The Kharmas 2027 page has every stretch in the year.

Vaishakh Weddings: What the Muhurat Engine Reports

An open calendar is not the same as a list of good days. With no closure in force, the engine’s marriage verdicts turn entirely on the five panchang limbs at sunrise (tithi, weekday, nakshatra, yoga and karana), and on those limbs few Vaishakh days pass:

The single cleared day is Wednesday 28 April, in the north’s dark half, with the Moon in Uttara Ashadha at sunrise; it falls before amanta Vaishakh begins, so the amanta month has none. Across the 12 distinct days in the two versions that miss by a single limb, the failing limb is the tithi on 4, the weekday on 4, the nakshatra on 2, and the yoga and the karana on one each. Akshaya Tritiya’s 8 May and the 9 May after it are among them: the engine tests both like any other day and rejects each on its weekday. After 28 April, the next day it clears is Monday 21 June, again with Uttara Ashadha, after both Vaishakhs are over.

These are the engine’s verdicts, not muhurats. A cleared day is only a candidate, and the engine’s own note on marriage says the pheras still need a lagna window calculated from both charts, which it does not compute. The day-by-day reasons are on the April, May and June 2027 marriage pages.

Where to Go Next

This page gives the edges of Vaishakh, its sunrises and dropped tithis, and the engine’s counts. It does not read a chart, choose a wedding date, or say what the month’s fasts or bathing customs achieve. The Phalgun month 2027 page works through the year’s last month the same way, the 2027 festival calendar has the full year, and each dated festival has its own page under festivals. In Hindi: वैशाख मास 2027 कब से कब तक: तारीखें और बुद्ध पूर्णिमा.
