Panchang in Sevan, Gegharkunik, Armenia Fri 22 Oct 1965

Dhanteras puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi runs from 00:18 on Fri 22 Oct to 21:58 on Fri 22 Oct, so only Friday’s pradosha (18:10–20:48) falls within it. No text giving Dhanteras’s time was found; pradosha is Tithika’s convention.

Dhanteras puja muhurat: pradosha, 18:10–20:48. Within it Vrishabha, a fixed (sthira) lagna, rises in the east from 19:13 to 20:48.

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, 07:18 here. Dwadashi ended at 00:18, before it. Trayodashi ends at 21:58, when the lead reaches 336°. The lead passed 180° at the full moon of 10 Oct, so the Moon is waning: Krishna paksha.

The night of Thu 21 Oct ran from sunset 18:11 Thu to sunrise 07:18, 13 h 7 m. Cut into 15 muhurtas of 52 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 07:18 to 18:10, splits into 8 choghadiyas of 1 h 21 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:10 to 07:19 Sat, splits into 8 choghadiyas of 1 h 38 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 19:01, for Hasta.

Add the Sun's and the Moon's places among the stars: 185.1° + 153° = 338.1°. The sum, cut into 27 parts of 13°20′, gives the yoga: 333°20′–346°40′ is the 26th, Indra. It ends at 20:40, then Vaidhriti.

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 11:06, when the lead reaches 330°; Vanija until 21:58.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 07:18 to 07:19 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, 24 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 24 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: 2 Apr 1965, 04:20 Fri. Since then the Sun has moved 196.4° round the stars. Vikram Samvat numbers that year 2022; Shaka Samvat numbers it 1887.
