Panchang in Ipameri, Goiás, Brazil Fri 23 May 1986

Buddha Purnima follows the tithi at sunrise. Purnima runs from 21:30 on Thu 22 May to 17:44 on Fri 23 May, so it holds sunrise only on Fri 23 May, at 06:33. 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: 168°–180° is the 15th, Shukla Purnima. A day takes the tithi in force at its sunrise, 06:33 here. Chaturdashi ended at 21:30 Thu, before it. Purnima ends at 17:44, when the lead reaches 180°. The lead passed 0° at the new moon of 8 May, so the Moon is waxing: Shukla paksha.

Sunrise here, 05:26, came before Chaturdashi ended at 06:00: this day reads Chaturdashi. Purnima ends at 02:14 Sat, before the next sunrise, so no day here reads Purnima: it is kshaya.

Sunrise here, 06:33, came after Chaturdashi ended at 21:30 Thu: this day reads Purnima.

The night of Thu 22 May ran from sunset 17:45 Thu to sunrise 06:33, 12 h 48 m. Cut into 15 muhurtas of 51 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:33 to 17:45, 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, 17:45 to 06:33 Sat, splits into 8 choghadiyas of 1 h 36 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 4 at 210°. It leaves at 09:12, for Anuradha.

Add the Sun's and the Moon's places among the stars: 38.3° + 211.7° = 250°. The sum, cut into 27 parts of 13°20′, gives the yoga: 240°00′–253°20′ is the 19th, Parigha. It ends at 11:34, then Shiva.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Purnima is Vishti and the second Bava. Vishti runs until 07:39, when the lead reaches 174°; Bava until 17:44.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:33 to 06:33 Sat, so the hours after midnight still belong to Shukrawara.

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, 7 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 8 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: 9 Apr 1986, 03:08 Wed. Since then the Sun has moved 42.9° round the stars. Vikram Samvat numbers that year 2043; Shaka Samvat numbers it 1908.
