Panchang in Ipameri, Goiás, Brazil Sun 11 Nov 2012

Dhanteras puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi runs from 05:58 on Sun 11 Nov to 03:03 on Mon 12 Nov, so only Sunday’s pradosha (19:24–21:37) falls within it. No text giving Dhanteras’s time was found; pradosha is Tithika’s convention.

Shiva’s Pradosh puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi runs from 05:58 on Sun 11 Nov to 03:03 on Mon 12 Nov, so only Sunday’s pradosha (19:24–21:37) 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 03:03 on Mon 12 Nov to 23:43 on Mon 12 Nov, between the two nights’ nishitha, touching neither. The Nirnayasindhu then takes the earlier day: Sun 11 Nov. 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, 06:29 here. Dwadashi ended at 05:58, before it. Trayodashi ends at 03:03 Mon, when the lead reaches 336°. The lead passed 180° at the full moon of 29 Oct, so the Moon is waning: Krishna paksha.

The night of Sat 10 Nov ran from sunset 19:23 Sat to sunrise 06:29, 11 h 6 m. Cut into 15 muhurtas of 44 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:29 to 19:24, 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 night here, 19:24 to 06:29 Mon, 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 fixed stars divide the Moon's path into 27 nakshatras of 13°20′, each in 4 padas of 3°20′. Hasta spans 160°00′–173°20′; the Moon entered its pada 3 at 166°40′. It leaves at 12:37, for Chitra.

Add the Sun's and the Moon's places among the stars: 205.3° + 169.6° = 374.9°, one full turn and 14.9°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 13°20′–26°40′ is the 2nd, Priti. It ends at 00:29 Mon, then Ayushmana.

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 16:34, when the lead reaches 330°; Vanija until 03:03 Mon.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:29 to 06:29 Mon, so the hours after midnight still belong to Raviwara.

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: Kanya gives Ashwina. The Sun enters Tula on 16 Oct, inside the month. The next new moon, 13 Nov, finds it in Tula and begins Kartika.

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 Nov, with the Sun in Tula, begins Kartika. Until then this Krishna paksha reads Kartika here, and Ashwina in the amanta count.

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 227° round the stars. Vikram Samvat numbers that year 2069; Shaka Samvat numbers it 1934.
