Panchang in Ipameri, Goiás, Brazil Tue 3 Apr 1973

Ghatasthapana is done in pratahkala, the first fifth of the day. Pratipada runs from 08:45 on Tue 3 Apr to 06:08 on Wed 4 Apr, between the two mornings’ pratahkala, touching neither. The Nirnayasindhu then takes the earlier day: Tue 3 Apr. No text giving Chaitra Navratri · Ghatasthapana’s time was found; pratahkala is Tithika’s convention.

Chaitra Navratri: every date in Ipameri

Vikram Samvat 2030 begins with Chaitra Shukla Pratipada. Here Pratipada holds no sunrise, so the year begins on the day it is current: Tue 3 Apr.

Nav Samvatsar: every date in Ipameri

Amavasya follows the tithi at sunrise. Amavasya runs from 10:58 on Mon 2 Apr to 08:45 on Tue 3 Apr, so it holds sunrise only on Tue 3 Apr, at 06:19. No text giving Amavasya’s time was found; sunrise is Tithika’s convention.

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 348°–360° is the 30th, Krishna Amavasya. A day takes the tithi in force at its sunrise, 06:19 here. Chaturdashi ended at 10:58 Mon, before it. Amavasya ends at 08:45, when the lead reaches 360°. The lead passed 180° at the full moon of 18 Mar, so the Moon is waning: Krishna paksha.

A day takes the tithi in force at its sunrise. Pratipada began at 08:45 and ended at 06:08 Wed, between the sunrises of 06:19 and 06:19 Wed. Tuesday reads Amavasya and Wednesday reads Dwitiya: Pratipada is a kshaya tithi here.

The night of Mon 2 Apr ran from sunset 18:13 Mon to sunrise 06:19, 12 h 6 m. Cut into 15 muhurtas of 48 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:19 to 18:12, 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 night here, 18:12 to 06:19 Wed, 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 fixed stars divide the Moon's path into 27 nakshatras of 13°20′, each in 4 padas of 3°20′. Revati spans 346°40′–360°00′; the Moon entered its pada 1 at 346°40′. It leaves at 01:13 Wed, for Ashwini.

Add the Sun's and the Moon's places among the stars: 350° + 348.6° = 698.6°, one full turn and 338.6°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 333°20′–346°40′ is the 26th, Indra. It ends at 18:50, then Vaidhriti.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Amavasya is Chatushpada and the second Nagava. Chatushpada ended at 21:55 Mon, when the lead reached 354°; Nagava runs until 08:45.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:19 to 06:19 Wed, so the hours after midnight still belong to Mangalawara.

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: Kumbha gives Phalguna. The Sun enters Meena on 14 Mar, inside the month. The next new moon, 3 Apr, finds it in Meena and begins Chaitra.

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 3 Apr, with the Sun in Meena, begins Chaitra. Until then this Krishna paksha reads Chaitra here, and Phalguna in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 3 Apr 1973, 08:45. Since then the Sun has moved -0.1° round the stars. Vikram Samvat numbers that year 2030; Shaka Samvat numbers it 1895.
