Panchang in Codcod, Western Visayas, Philippines Sat 8 Nov 1980

Govardhan Puja is done in pratahkala, the first fifth of the day. Pratipada began at 04:42 on Sat 8 Nov, before that morning’s pratahkala, and ended at 06:50 on Sun 9 Nov, partway into the next. The Nirnayasindhu takes the morning Pratipada fills: Sat 8 Nov. No text giving Govardhan Puja’s time was found; pratahkala is Tithika’s convention.

Govardhan Puja: every date in Codcod

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, 05:40 here. Amavasya ended at 04:42, before it. Pratipada ends at 06:50 Sun, when the lead reaches 12°. The lead passed 0° at the new moon of 8 Nov, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise. Pratipada began at 04:42, before sunrise at 05:40, and ends at 06:50 Sun, after the next sunrise at 05:40 Sun. Both days read Pratipada: it is a vriddhi tithi here.

The night of Fri 7 Nov ran from sunset 17:21 Fri to sunrise 05:40, 12 h 19 m. Cut into 15 muhurtas of 49 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:40 to 17:21, splits into 8 choghadiyas of 1 h 27 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 17:21 to 05:40 Sun, splits into 8 choghadiyas of 1 h 32 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′. Vishakha spans 200°00′–213°20′; the Moon entered its pada 1 at 200°. It leaves at 03:18 Sun, for Anuradha.

Add the Sun's and the Moon's places among the stars: 202.1° + 202.5° = 404.6°, one full turn and 44.6°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 40°00′–53°20′ is the 4th, Saubhagya. It ends at 21:51, then Shobhana.

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 17:48, when the lead reaches 6°; Bava until 06:50 Sun.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:40 to 05:40 Sun, so the hours after midnight still belong to Shaniwara.

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, 7 Dec, 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 8 Nov, 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: 17 Mar 1980, 02:55 Mon. Since then the Sun has moved 229.3° round the stars. Vikram Samvat numbers that year 2037; Shaka Samvat numbers it 1902.
