Dhanteras puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi runs from 13:45 on Thu 27 Oct to 15:50 on Fri 28 Oct, so only Thursday’s pradosha (16:50–19:46) 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 13:45 on Thu 27 Oct to 15:50 on Fri 28 Oct, so only Thursday’s pradosha (16:50–19:46) 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: 312°–324° is the 27th, Krishna Dwadashi. A day takes the tithi in force at its sunrise, 07:28 here. Ekadashi ended at 12:00 Wed, before it. Dwadashi ends at 13:45, when the lead reaches 324°. The lead passed 180° at the full moon of 16 Oct, so the Moon is waning: Krishna paksha.

The night of Wed 26 Oct ran from sunset 16:52 Wed to sunrise 07:28, 14 h 36 m. Cut into 15 muhurtas of 58 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 07:28 to 16:50, splits into 8 choghadiyas of 1 h 10 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 16:50 to 07:30 Fri, splits into 8 choghadiyas of 1 h 50 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′. Uttara Phalguni spans 146°40′–160°00′; the Moon entered its pada 2 at 150°. It leaves at 00:58 Fri, for Hasta.

Add the Sun's and the Moon's places among the stars: 190.1° + 151.2° = 341.3°. The sum, cut into 27 parts of 13°20′, gives the yoga: 333°20′–346°40′ is the 26th, Indra. It ends at 17:20, then Vaidhriti.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Dwadashi is Kaulava and the second Taitila. Kaulava ended at 00:50, when the lead reached 318°; Taitila runs until 13:45.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 07:28 to 07:30 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: Kanya gives Ashwina. The Sun enters Tula on 17 Oct, inside the month. The next new moon, 30 Oct, 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 30 Oct, 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: 7 Apr 2016, 14:23 Thu. Since then the Sun has moved 196.1° round the stars. Vikram Samvat numbers that year 2073; Shaka Samvat numbers it 1938.
