Panchang in Ipameri, Goiás, Brazil Thu 27 Sep 1973

Ghatasthapana is done in pratahkala, the first fifth of the day. Pratipada runs from 10:53 on Wed 26 Sep to 10:06 on Thu 27 Sep, so only Thursday’s pratahkala (05:58–08:24) falls within it.

Sharad Navratri: 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, 05:58 here. Amavasya ended at 10:53 Wed, before it. Pratipada ends at 10:06, when the lead reaches 12°. The lead passed 0° at the new moon of 26 Sep, so the Moon is waxing: Shukla paksha.

The night of Wed 26 Sep ran from sunset 18:09 Wed to sunrise 05:58, 11 h 49 m. Cut into 15 muhurtas of 47 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:58 to 18:09, splits into 8 choghadiyas of 1 h 31 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:09 to 05:57 Fri, splits into 8 choghadiyas of 1 h 28 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′. Hasta spans 160°00′–173°20′; the Moon entered its pada 4 at 170°. It leaves at 11:06, for Chitra.

Add the Sun's and the Moon's places among the stars: 160.6° + 170.5° = 331.1°. The sum, cut into 27 parts of 13°20′, gives the yoga: 320°00′–333°20′ is the 25th, Brahma. It ends at 09:42, then Indra.

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 ended at 22:26 Wed, when the lead reached 6°; Bava runs until 10:06.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:58 to 05:57 Fri, so the hours after midnight still belong to Guruwara.

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 16 Oct, inside the month. The next new moon, 26 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 26 Sep, with the Sun in Kanya, began Ashwina. This Shukla paksha reads Ashwina in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 3 Apr 1973, 08:45 Tue. Since then the Sun has moved 170.5° round the stars. Vikram Samvat numbers that year 2030; Shaka Samvat numbers it 1895.
