Panchang in Ipameri, Goiás, Brazil Sun 8 May 2016

Akshaya Tritiya’s puja is done in purvahna, the first half of the day. Tritiya runs from 09:21 on Sun 8 May to 06:22 on Mon 9 May, so it touches only Sunday’s purvahna (06:28–12:09).

Akshaya Tritiya: every date in Ipameri

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 12°–24° is the 2nd, Shukla Dwitiya. A day takes the tithi in force at its sunrise, 06:28 here. Pratipada ended at 12:47 Sat, before it. Dwitiya ends at 09:21, when the lead reaches 24°. 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. Tritiya began at 09:21 and ended at 06:22 Mon, between the sunrises of 06:28 and 06:28 Mon. Sunday reads Dwitiya and Monday reads Chaturthi: Tritiya is a kshaya tithi here.

The night of Sat 7 May ran from sunset 17:50 Sat to sunrise 06:28, 12 h 38 m. Cut into 15 muhurtas of 50 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:28 to 17:50, splits into 8 choghadiyas of 1 h 25 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 17:50 to 06:28 Mon, splits into 8 choghadiyas of 1 h 34 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′. Rohini spans 40°00′–53°20′; the Moon entered its pada 2 at 43°20′. It leaves at 17:36, for Mrigashira.

Add the Sun's and the Moon's places among the stars: 24.1° + 46.5° = 70.6°. The sum, cut into 27 parts of 13°20′, gives the yoga: 66°40′–80°00′ is the 6th, Atiganda. It ends at 20:48, then Sukarma.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Dwitiya is Balava and the second Kaulava. Balava ended at 23:01 Sat, when the lead reached 18°; Kaulava runs until 09:21.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:28 to 06:28 Mon, so the hours after midnight still belong to Raviwara.

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, 4 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 2016, 08:23 Thu. Since then the Sun has moved 30.1° round the stars. Vikram Samvat numbers that year 2073; Shaka Samvat numbers it 1938.
