Panchang in Ipameri, Goiás, Brazil Sat 3 Nov 2018

Dhanteras puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi runs from 17:54 on Sat 3 Nov to 16:17 on Mon 5 Nov, so only Saturday’s pradosha (19:20 Sun–21:34 Sun) falls within it. No text giving Dhanteras’s time was found; pradosha is Tithika’s convention.

Dhanteras puja muhurat: pradosha, 19:20 Sun–21:34 Sun. Within it Vrishabha, a fixed (sthira) lagna, rises in the east from 20:08 Sun to 21:34 Sun.

Shiva’s Pradosh puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi runs from 17:54 on Sat 3 Nov to 16:17 on Mon 5 Nov, so only Saturday’s pradosha (19:20 Sun–21:34 Sun) falls within it. No text giving Pradosh Vrat’s time was found; pradosha is Tithika’s convention.

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 300°–312° is the 26th, Krishna Ekadashi. A day takes the tithi in force at its sunrise, 05:32 here. Dashami ended at 20:40 Fri, before it. Ekadashi ends at 18:44, when the lead reaches 312°. The lead passed 180° at the full moon of 24 Oct, so the Moon is waning: Krishna paksha.

The night of Fri 2 Nov ran from sunset 18:19 Fri to sunrise 05:32, 11 h 13 m. Cut into 15 muhurtas of 44 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:32 to 18:19, splits into 8 choghadiyas of 1 h 35 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:19 to 06:32 Sun, splits into 8 choghadiyas of 1 h 24 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′. Purva Phalguni spans 133°20′–146°40′; the Moon entered its pada 3 at 140°. It leaves at 14:14, for Uttara Phalguni.

Add the Sun's and the Moon's places among the stars: 196.7° + 141.6° = 338.3°. The sum, cut into 27 parts of 13°20′, gives the yoga: 333°20′–346°40′ is the 26th, Indra. It ends at 18:50, then Vaidhriti.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Ekadashi is Bava and the second Balava. Bava runs until 07:41, when the lead reaches 306°; Balava until 18:44.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:32 to 06:32 Sun, so the hours after midnight still belong to Shaniwara.

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 17 Oct, inside the month. The next new moon, 7 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 7 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: 17 Mar 2018, 10:11 Sat. Since then the Sun has moved 223.9° round the stars. Vikram Samvat numbers that year 2075; Shaka Samvat numbers it 1940.
