Panchang in Ipameri, Goiás, Brazil Fri 20 Mar 2015

Ghatasthapana is done in pratahkala, the first fifth of the day. Pratipada runs from 06:36 on Fri 20 Mar to 03:02 on Sat 21 Mar, so it touches only Friday’s pratahkala (06:16–08:42). No text giving Chaitra Navratri · Ghatasthapana’s time was found; pratahkala is Tithika’s convention.

Chaitra Navratri: every date in Ipameri

Vikram Samvat 2072 begins with Chaitra Shukla Pratipada. Here Pratipada holds no sunrise, so the year begins on the day it is current: Fri 20 Mar.

Amavasya follows the tithi at sunrise. Amavasya runs from 10:18 on Thu 19 Mar to 06:36 on Fri 20 Mar, so it holds sunrise only on Fri 20 Mar, at 06:16. 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, 06:16 here. Chaturdashi ended at 10:18 Thu, before it. Amavasya ends at 06:36, when the lead reaches 360°. The lead passed 180° at the full moon of 5 Mar, so the Moon is waning: Krishna paksha.

A day takes the tithi in force at its sunrise. Pratipada began at 06:36 and ended at 03:02 Sat, between the sunrises of 06:16 and 06:16 Sat. Friday reads Amavasya and Saturday reads Dwitiya: Pratipada is a kshaya tithi here.

The night of Thu 19 Mar ran from sunset 18:24 Thu to sunrise 06:16, 11 h 52 m. Cut into 15 muhurtas of 47 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:16 to 18:23, 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, 18:23 to 06:16 Sat, 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 Bhadrapada spans 333°20′–346°40′; the Moon entered its pada 1 at 333°20′. It leaves at 00:32 Sat, for Revati.

Add the Sun's and the Moon's places among the stars: 335.4° + 335.2° = 670.6°, one full turn and 310.6°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 306°40′–320°00′ is the 24th, Shukla. It ends at 20:21, then Brahma.

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 20:26 Thu, when the lead reached 354°; Nagava runs until 06:36.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:16 to 06:16 Sat, so the hours after midnight still belong to Shukrawara.

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, 20 Mar, 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 20 Mar, 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: 20 Mar 2015, 06:36. Since then the Sun has moved 0° round the stars. Vikram Samvat numbers that year 2072; Shaka Samvat numbers it 1937.
