Panchang in Ipameri, Goiás, Brazil Wed 20 Sep 2017

Ghatasthapana is done in pratahkala, the first fifth of the day. Pratipada runs from 02:29 on Wed 20 Sep to 02:04 on Thu 21 Sep, so only Wednesday’s pratahkala (06:03–08:28) 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, 06:03 here. Amavasya ended at 02:29, before it. Pratipada ends at 02:04 Thu, when the lead reaches 12°. The lead passed 0° at the new moon of 20 Sep, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise.

The night of Tue 19 Sep ran from sunset 18:08 Tue to sunrise 06:03, 11 h 55 m. Cut into 15 muhurtas of 47 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:03 to 18:08, splits into 8 choghadiyas of 1 h 30 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:08 to 06:03 Thu, splits into 8 choghadiyas of 1 h 29 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′. Uttara Phalguni spans 146°40′–160°00′; the Moon entered its pada 3 at 153°20′. It leaves at 14:32, for Hasta.

Add the Sun's and the Moon's places among the stars: 153.5° + 155.3° = 308.8°. The sum, cut into 27 parts of 13°20′, gives the yoga: 306°40′–320°00′ is the 24th, Shukla. It ends at 01:01 Thu, then Brahma.

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 14:13, when the lead reaches 6°; Bava until 02:04 Thu.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:03 to 06:03 Thu, so the hours after midnight still belong to Budhawara.

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, 19 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 20 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: 27 Mar 2017, 23:57 Mon. Since then the Sun has moved 170° round the stars. Vikram Samvat numbers that year 2074; Shaka Samvat numbers it 1939.
