Panchang in Sevan, Gegharkunik, Armenia Tue 12 Jul 1983

Rath Yatra follows the tithi at sunrise. Dwitiya runs from 13:40 on Mon 11 Jul to 10:00 on Tue 12 Jul, so it holds sunrise only on Tue 12 Jul, at 06:39. No text giving Rath Yatra’s time was found; sunrise is Tithika’s convention.

Rath Yatra: every date in Sevan

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, 06:39 here. Pratipada ended at 13:40 Mon, before it. Dwitiya ends at 10:00, when the lead reaches 24°. The lead passed 0° at the new moon of 10 Jul, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise. Tritiya began at 10:00 and ended at 06:28 Wed, between the sunrises of 06:39 and 06:40 Wed. Tuesday reads Dwitiya and Wednesday reads Chaturthi: Tritiya is a kshaya tithi here.

The night of Mon 11 Jul ran from sunset 21:31 Mon to sunrise 06:39, 9 h 8 m. Cut into 15 muhurtas of 36 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:39 to 21:31, splits into 8 choghadiyas of 1 h 51 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 21:31 to 06:40 Wed, splits into 8 choghadiyas of 1 h 8 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′. Ashlesha spans 106°40′–120°00′; the Moon entered its pada 1 at 106°40′. It leaves at 02:28 Wed, for Magha.

Add the Sun's and the Moon's places among the stars: 85.5° + 107.6° = 193.1°. The sum, cut into 27 parts of 13°20′, gives the yoga: 186°40′–200°00′ is the 15th, Vajra. It ends at 16:57, then Siddhi.

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 23:50 Mon, when the lead reached 18°; Kaulava runs until 10:00.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:39 to 06:40 Wed, so the hours after midnight still belong to Mangalawara.

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, 9 Aug, 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 10 Jul, 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: 13 Apr 1983, 12:58 Wed. Since then the Sun has moved 86.3° round the stars. Vikram Samvat numbers that year 2040; Shaka Samvat numbers it 1905.
