Panchang in Ipameri, Goiás, Brazil Sat 11 Jun 1904

Shiva’s Pradosh puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi runs from 21:18 on Fri 10 Jun to 20:52 on Sat 11 Jun, so only Saturday’s pradosha (17:38–20:13) falls within it. No text giving Pradosh Vrat’s time was found; pradosha is Tithika’s convention.

Pradosh Vrat: every date in Ipameri

Shiva’s worship centres on nishitha, the midnight muhurta. Chaturdashi runs from 20:52 on Sat 11 Jun to 19:45 on Sun 12 Jun, so only Saturday night’s nishitha (23:39–00:31 Sun) 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 21:24 Fri, before it. Trayodashi ends at 20:58, 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 Fri 10 Jun ran from sunset 17:44 Fri 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 Sun, 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 07:36, for Krittika.

Add the Sun's and the Moon's places among the stars: 57.5° + 26.1° = 83.6°. The sum, cut into 27 parts of 13°20′, gives the yoga: 80°00′–93°20′ is the 7th, Sukarma. It ends at 23:01, then Dhriti.

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 09:17, when the lead reaches 330°; Vanija until 20:58.

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

A month normally holds one sankranti, the Sun's entry into a new rashi. From 15 May 07:57 Sun to 13 Jun 18:10 Mon the Sun stayed in Vrishabha, entering Mithuna at 13 Jun 21:50 Mon, 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 13 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: 17 Mar 1904, 02:39 Thu. Since then the Sun has moved 83.8° round the stars. Vikram Samvat numbers that year 1961; Shaka Samvat numbers it 1826.
