Panchang in Ipameri, Goiás, Brazil Wed 21 May 1997

Buddha Purnima follows the tithi at sunrise. Purnima begins at 06:38 on Wed 21 May, after that sunrise, and ends at 06:13 on Thu 22 May, before the next: it holds no sunrise. A tithi that holds no sunrise is kept on the day it is current: Wed 21 May. No text giving Buddha Purnima’s time was found; sunrise is Tithika’s convention.

Purnima: every date in Ipameri

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 156°–168° is the 14th, Shukla Chaturdashi. A day takes the tithi in force at its sunrise, 06:32 here. Trayodashi ended at 06:27 Tue, before it. Chaturdashi ends at 06:38, when the lead reaches 168°. The lead passed 0° at the new moon of 6 May, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise. Purnima began at 06:38 and ended at 06:13 Thu, between the sunrises of 06:32 and 06:32 Thu. Wednesday reads Chaturdashi and Thursday reads Pratipada: Purnima is a kshaya tithi here.

A day takes the tithi in force at its sunrise. Chaturdashi began at 06:27 Tue, before sunrise at 06:32 Tue, and ends at 06:38, after the next sunrise at 06:32. Both days read Chaturdashi: it is a vriddhi tithi here.

The night of Tue 20 May ran from sunset 17:46 Tue to sunrise 06:32, 12 h 46 m. Cut into 15 muhurtas of 51 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:32 to 17:46, splits into 8 choghadiyas of 1 h 24 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 17:46 to 06:32 Thu, splits into 8 choghadiyas of 1 h 35 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The fixed stars divide the Moon's path into 27 nakshatras of 13°20′, each in 4 padas of 3°20′. Vishakha spans 200°00′–213°20′; the Moon entered its pada 2 at 203°20′. It leaves at 22:41, for Anuradha.

Add the Sun's and the Moon's places among the stars: 36.6° + 204.5° = 241.1°. The sum, cut into 27 parts of 13°20′, gives the yoga: 240°00′–253°20′ is the 19th, Parigha. It ends at 03:25 Thu, then Shiva.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Chaturdashi is Garaja and the second Vanija. Garaja ended at 18:37 Tue, when the lead reached 162°; Vanija runs until 06:38.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:32 to 06:32 Thu, so the hours after midnight still belong to Budhawara.

An amanta month runs from new moon to new moon and takes its name from the rashi the Sun is in at the new moon that begins it: Mesha gives Vaishakha. The Sun enters Vrishabha on 14 May, inside the month. The next new moon, 5 Jun, finds it in Vrishabha and begins Jyeshtha.

A purnimanta month runs from full moon to full moon, so its waning half comes first. It shares its name with the amanta month that its second half falls in: the new moon of 6 May, with the Sun in Mesha, began Vaishakha. This Shukla paksha reads Vaishakha in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 7 Apr 1997, 08:01 Mon. Since then the Sun has moved 42.7° round the stars. Vikram Samvat numbers that year 2054; Shaka Samvat numbers it 1919.
