Panchang in Ipameri, Goiás, Brazil Thu 17 Jun 1993

Shiva’s Pradosh puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi runs from 23:02 on Wed 16 Jun to 23:35 on Thu 17 Jun, so only Thursday’s pradosha (17:45–20:21) 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 23:35 on Thu 17 Jun to 23:31 on Fri 18 Jun, so only Thursday night’s nishitha (23:47–00:39 Fri) falls within it. No text giving Masik Shivratri’s time was found; nishitha is Tithika’s convention.

Masik Shivratri: every date in Ipameri

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, 06:41 here. Dwadashi ended at 23:02 Wed, before it. Trayodashi ends at 23:35, when the lead reaches 336°. The lead passed 180° at the full moon of 4 Jun, so the Moon is waning: Krishna paksha.

The night of Wed 16 Jun ran from sunset 17:45 Wed to sunrise 06:41, 12 h 56 m. Cut into 15 muhurtas of 51 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:41 to 17:45, 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, 17:45 to 06:41 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′. Krittika spans 26°40′–40°00′; the Moon entered its pada 2 at 30°. It leaves at 01:15 Fri, for Rohini.

Add the Sun's and the Moon's places among the stars: 62.4° + 30.1° = 92.5°. The sum, cut into 27 parts of 13°20′, gives the yoga: 80°00′–93°20′ is the 7th, Sukarma. It ends at 08:01, 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 11:23, when the lead reaches 330°; Vanija until 23:35.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:41 to 06:41 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: Vrishabha gives Jyeshtha. The Sun enters Mithuna on 14 Jun, inside the month. The next new moon, 19 Jun, finds it in Mithuna and begins Ashadha.

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, begins Ashadha. Until then this Krishna paksha reads Ashadha here, and Jyeshtha in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 23 Mar 1993, 04:14 Tue. Since then the Sun has moved 83.5° round the stars. Vikram Samvat numbers that year 2050; Shaka Samvat numbers it 1915.
