Panchang in Sevan, Gegharkunik, Armenia Mon 31 Oct 2016

Govardhan Puja is done in pratahkala, the first fifth of the day. Pratipada runs from 21:38 on Sun 30 Oct to 00:09 on Tue 1 Nov, so only Monday’s pratahkala (07:28–09:34) falls within it. No text giving Govardhan Puja’s time was found; pratahkala is Tithika’s convention.

Govardhan Puja: every date in Sevan

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 0°–12° is the 1st, Shukla Pratipada. A day takes the tithi in force at its sunrise, 07:28 here. Amavasya ended at 21:38 Sun, before it. Pratipada ends at 00:09 Tue, when the lead reaches 12°. The lead passed 0° at the new moon of 30 Oct, so the Moon is waxing: Shukla paksha.

The night of Sun 30 Oct ran from sunset 17:58 Sun to sunrise 07:28, 13 h 30 m. Cut into 15 muhurtas of 54 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 07:28 to 17:57, splits into 8 choghadiyas of 1 h 18 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 17:57 to 07:30 Tue, splits into 8 choghadiyas of 1 h 41 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 4 at 196°40′. It leaves at 10:30, for Vishakha.

Add the Sun's and the Moon's places among the stars: 194° + 198.5° = 392.5°, one full turn and 32.5°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 26°40′–40°00′ is the 3rd, Ayushmana. It ends at 21:23, then Saubhagya.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Pratipada is Kinstughna and the second Bava. Kinstughna runs until 10:53, when the lead reaches 6°; Bava until 00:09 Tue.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 07:28 to 07:30 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: Tula gives Kartika. The Sun enters Vrishchika on 16 Nov, inside the month. The next new moon, 29 Nov, finds it in Vrishchika and begins Margashirsha.

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, began Kartika. This Shukla paksha reads Kartika in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 7 Apr 2016, 15:23 Thu. Since then the Sun has moved 200° round the stars. Vikram Samvat numbers that year 2073; Shaka Samvat numbers it 1938.
