Panchang in Ipameri, Goiás, Brazil Mon 28 Oct 2019

Govardhan Puja is done in pratahkala, the first fifth of the day. Pratipada runs from 00:38 on Mon 28 Oct to 21:43 on Mon 28 Oct, so only Monday’s pratahkala (05:36–08:08) falls within it. No text giving Govardhan Puja’s time was found; pratahkala is Tithika’s convention.

Govardhan Puja: every date in Ipameri

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, 05:36 here. Amavasya ended at 00:38, before it. Pratipada ends at 21:43, when the lead reaches 12°. The lead passed 0° at the new moon of 28 Oct, so the Moon is waxing: Shukla paksha.

Sunrise here, 06:29, came before Amavasya ended at 09:08: this day reads Amavasya. Pratipada ends at 06:13 Tue, before the next sunrise, so no day here reads Pratipada: it is kshaya.

The night of Sun 27 Oct ran from sunset 18:17 Sun to sunrise 05:36, 11 h 19 m. Cut into 15 muhurtas of 45 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:36 to 18:17, splits into 8 choghadiyas of 1 h 35 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:17 to 05:35 Tue, splits into 8 choghadiyas of 1 h 24 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 3 at 193°20′. It leaves at 16:30, for Vishakha.

Add the Sun's and the Moon's places among the stars: 190.5° + 193.4° = 383.9°, one full turn and 23.9°. 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 09:55, then Ayushmana.

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 11:07, when the lead reaches 6°; Bava until 21:43.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:36 to 05:35 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, 26 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 28 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: 5 Apr 2019, 05:50 Fri. Since then the Sun has moved 199.3° round the stars. Vikram Samvat numbers that year 2076; Shaka Samvat numbers it 1941.
