Panchang in Sevan, Gegharkunik, Armenia Mon 28 Oct 2019

Govardhan Puja is done in pratahkala, the first fifth of the day. Pratipada runs from 07:38 on Mon 28 Oct to 04:43 on Tue 29 Oct, so it touches only Monday’s pratahkala (07:24–09:32). No text giving Govardhan Puja’s time was found; pratahkala is Tithika’s convention.

Govardhan Puja: every date in Sevan

Amavasya follows the tithi at sunrise. Amavasya runs from 10:53 on Sun 27 Oct to 07:38 on Mon 28 Oct, so it holds sunrise only on Mon 28 Oct, at 07:24. No text giving Amavasya’s time was found; sunrise is Tithika’s convention.

Amavasya: every date in Sevan

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 348°–360° is the 30th, Krishna Amavasya. A day takes the tithi in force at its sunrise, 07:24 here. Chaturdashi ended at 10:53 Sun, before it. Amavasya ends at 07:38, when the lead reaches 360°. The lead passed 180° at the full moon of 14 Oct, so the Moon is waning: Krishna paksha.

A day takes the tithi in force at its sunrise. Pratipada began at 07:38 and ended at 04:43 Tue, between the sunrises of 07:24 and 07:25 Tue. Monday reads Amavasya and Tuesday reads Dwitiya: Pratipada is a kshaya tithi here.

The night of Sun 27 Oct ran from sunset 18:03 Sun to sunrise 07:24, 13 h 21 m. Cut into 15 muhurtas of 53 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 07:24 to 18:02, splits into 8 choghadiyas of 1 h 19 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:02 to 07:25 Tue, splits into 8 choghadiyas of 1 h 40 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′. Swati spans 186°40′–200°00′; the Moon entered its pada 2 at 190°. It leaves at 23:30, for Vishakha.

Add the Sun's and the Moon's places among the stars: 190.3° + 190.1° = 380.4°, one full turn and 20.4°. 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 16:55, then Ayushmana.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Amavasya is Chatushpada and the second Nagava. Chatushpada ended at 21:14 Sun, when the lead reached 354°; Nagava runs until 07:38.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 07:24 to 07:25 Tue, so the hours after midnight still belong to Somawara.

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, 28 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 28 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: 5 Apr 2019, 12:50 Fri. Since then the Sun has moved 199.1° round the stars. Vikram Samvat numbers that year 2076; Shaka Samvat numbers it 1941.
