Dhanteras puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi runs from 03:32 on Fri 17 Oct to 00:49 on Sat 18 Oct, so only Friday’s pradosha (17:28–19:54) falls within it. No text giving Dhanteras’s time was found; pradosha is Tithika’s convention.

Shiva’s worship centres on nishitha, the midnight muhurta. Chaturdashi runs from 00:49 on Sat 18 Oct to 22:12 on Sat 18 Oct, between the two nights’ nishitha, touching neither. The Nirnayasindhu then takes the earlier day: Fri 17 Oct. 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, 05:36 here. Dwadashi ended at 03:32, before it. Trayodashi ends at 00:49 Sat, when the lead reaches 336°. The lead passed 180° at the full moon of 5 Oct, so the Moon is waning: Krishna paksha.

The night of Thu 16 Oct ran from sunset 17:29 Thu to sunrise 05:36, 12 h 7 m. Cut into 15 muhurtas of 48 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:36 to 17:28, splits into 8 choghadiyas of 1 h 29 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 17:28 to 05:36 Sat, splits into 8 choghadiyas of 1 h 31 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 4 at 143°20′. It leaves at 08:31, for Uttara Phalguni.

Add the Sun's and the Moon's places among the stars: 179.7° + 144.9° = 324.6°. The sum, cut into 27 parts of 13°20′, gives the yoga: 320°00′–333°20′ is the 25th, Brahma. It ends at 19:03, then Indra.

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 14:10, when the lead reaches 330°; Vanija until 00:49 Sat.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:36 to 05:36 Sat, so the hours after midnight still belong to Shukrawara.

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, 19 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 19 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: 28 Mar 2036, 04:56 Fri. Since then the Sun has moved 196.3° round the stars. Vikram Samvat numbers that year 2093; Shaka Samvat numbers it 1958.
