Panchang in Atliaca, Guerrero, Mexico Wed 6 May 2020

Buddha Purnima follows the tithi at sunrise. Purnima begins at 09:15 on Wed 6 May, after that sunrise, and ends at 05:45 on Thu 7 May, before the next: it holds no sunrise. A tithi that holds no sunrise is kept on the day it is current: Wed 6 May. No text giving Buddha Purnima’s time was found; sunrise is Tithika’s convention.

Purnima: every date in Atliaca

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, 07:08 here. Trayodashi ended at 12:51 Tue, before it. Chaturdashi ends at 09:15, when the lead reaches 168°. The lead passed 0° at the new moon of 22 Apr, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise. Purnima began at 09:15 and ended at 05:45 Thu, between the sunrises of 07:08 and 07:08 Thu. Wednesday reads Chaturdashi and Thursday reads Pratipada: Purnima is a kshaya tithi here.

The night of Tue 5 May ran from sunset 19:59 Tue to sunrise 07:08, 11 h 9 m. Cut into 15 muhurtas of 44 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 07:08 to 20:00, 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 night here, 20:00 to 07:08 Thu, splits into 8 choghadiyas of 1 h 23 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′. Swati spans 186°40′–200°00′; the Moon entered its pada 1 at 186°40′. It leaves at 00:37 Thu, for Vishakha.

Add the Sun's and the Moon's places among the stars: 22.3° + 189° = 211.3°. The sum, cut into 27 parts of 13°20′, gives the yoga: 200°00′–213°20′ is the 16th, Siddhi. It ends at 10:08, then Vyatipata.

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 23:03 Tue, when the lead reached 162°; Vanija runs until 09:15.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 07:08 to 07:08 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, 22 May, 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 22 Apr, 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: 24 Mar 2020, 03:28 Tue. Since then the Sun has moved 42.2° round the stars. Vikram Samvat numbers that year 2077; Shaka Samvat numbers it 1942.
