Panchang in Ipameri, Goiás, Brazil Tue 10 Jun 1980

Shiva’s Pradosh puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi runs from 00:44 on Tue 10 Jun to 22:07 on Tue 10 Jun, so only Tuesday’s pradosha (17:44–20:19) falls within it. No text giving Pradosh Vrat’s time was found; pradosha is Tithika’s convention.

Shiva’s worship centres on nishitha, the midnight muhurta. Chaturdashi runs from 22:07 on Tue 10 Jun to 19:42 on Wed 11 Jun, so only Tuesday night’s nishitha (23:46–00:38 Wed) falls within it. No text giving Masik Shivratri’s time was found; nishitha is Tithika’s convention.

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 324°–336° is the 28th, Krishna Trayodashi. A day takes the tithi in force at its sunrise, 06:39 here. Dwadashi ended at 00:44, before it. Trayodashi ends at 22:07, when the lead reaches 336°. The lead passed 180° at the full moon of 29 May, so the Moon is waning: Krishna paksha.

The night of Mon 9 Jun ran from sunset 17:44 Mon to sunrise 06:39, 12 h 55 m. Cut into 15 muhurtas of 51 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:39 to 17:44, 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, 17:44 to 06:39 Wed, 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′. Bharani spans 13°20′–26°40′; the Moon entered its pada 4 at 23°20′. It leaves at 12:06, for Krittika.

Add the Sun's and the Moon's places among the stars: 56.1° + 23.4° = 79.5°. The sum, cut into 27 parts of 13°20′, gives the yoga: 66°40′–80°00′ is the 6th, Atiganda. It ends at 07:29, then Sukarma.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Trayodashi is Garaja and the second Vanija. Garaja runs until 11:25, when the lead reaches 330°; Vanija until 22:07.

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

A month normally holds one sankranti, the Sun's entry into a new rashi. From 14 May 09:00 Wed to 12 Jun 17:38 Thu the Sun stayed in Vrishabha, entering Mithuna at 14 Jun 09:25 Sat, after the new moon. A month with no sankranti is Adhika Jyeshtha, before Jyeshtha itself.

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 12 Jun, with the Sun in Vrishabha, begins Jyeshtha (Adhik). Until then this Krishna paksha reads Jyeshtha (Adhik) here, and Jyeshtha (Adhik) in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 16 Mar 1980, 15:55 Sun. Since then the Sun has moved 83.3° round the stars. Vikram Samvat numbers that year 2037; Shaka Samvat numbers it 1902.
