Panchang in Ipameri, Goiás, Brazil Thu 21 Jun 2012

Rath Yatra follows the tithi at sunrise. Dwitiya runs from 13:36 on Wed 20 Jun to 14:44 on Thu 21 Jun, so it holds sunrise only on Thu 21 Jun, at 06:42. No text giving Rath Yatra’s time was found; sunrise is Tithika’s convention.

Rath Yatra: 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, 06:42 here. Pratipada ended at 13:36 Wed, before it. Dwitiya ends at 14:44, when the lead reaches 24°. The lead passed 0° at the new moon of 19 Jun, so the Moon is waxing: Shukla paksha.

The night of Wed 20 Jun ran from sunset 17:46 Wed to sunrise 06:42, 12 h 56 m. Cut into 15 muhurtas of 51 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:42 to 17:46, 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 night here, 17:46 to 06:42 Fri, splits into 8 choghadiyas of 1 h 37 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′. Punarvasu spans 80°00′–93°20′; the Moon entered its pada 2 at 83°20′. It leaves at 19:46, for Pushya.

Add the Sun's and the Moon's places among the stars: 66.4° + 86.5° = 152.9°. The sum, cut into 27 parts of 13°20′, gives the yoga: 146°40′–160°00′ is the 12th, Dhruva. It ends at 19:20, then Vyaghata.

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 02:13, when the lead reached 18°; Kaulava runs until 14:44.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:42 to 06:42 Fri, so the hours after midnight still belong to Guruwara.

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: Mithuna gives Ashadha. The Sun enters Karka on 16 Jul, inside the month. The next new moon, 19 Jul, finds it in Karka and begins Shravana.

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 19 Jun, with the Sun in Mithuna, began Ashadha. This Shukla paksha reads Ashadha in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 22 Mar 2012, 11:37 Thu. Since then the Sun has moved 88.1° round the stars. Vikram Samvat numbers that year 2069; Shaka Samvat numbers it 1934.
