Panchang in Ipameri, Goiás, Brazil Sun 11 Jun 1972

Vat Savitri Vrat follows the tithi at sunrise. Amavasya runs from 11:52 on Sat 10 Jun to 08:29 on Sun 11 Jun, so it holds sunrise only on Sun 11 Jun, at 06:39. No text giving Vat Savitri Vrat’s time was found; sunrise is Tithika’s convention.

Amavasya: every date in Ipameri

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, 06:39 here. Chaturdashi ended at 11:52 Sat, before it. Amavasya ends at 08:29, when the lead reaches 360°. The lead passed 180° at the full moon of 28 May, so the Moon is waning: Krishna paksha.

A day takes the tithi in force at its sunrise. Pratipada began at 08:29 and ended at 05:24 Mon, between the sunrises of 06:39 and 06:40 Mon. Sunday reads Amavasya and Monday reads Dwitiya: Pratipada is a kshaya tithi here.

The night of Sat 10 Jun ran from sunset 17:44 Sat to sunrise 06:39, 12 h 55 m. Cut into 15 muhurtas of 51 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:39 to 17:44, splits into 8 choghadiyas of 1 h 23 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 17:44 to 06:40 Mon, splits into 8 choghadiyas of 1 h 37 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′. Mrigashira spans 53°20′–66°40′; the Moon entered its pada 1 at 53°20′. It leaves at 23:58, for Ardra.

Add the Sun's and the Moon's places among the stars: 57.1° + 56° = 113.1°. The sum, cut into 27 parts of 13°20′, gives the yoga: 106°40′–120°00′ is the 9th, Shula. It ends at 17:11, then Ganda.

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 22:09 Sat, when the lead reached 354°; Nagava runs until 08:29.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:39 to 06:40 Mon, so the hours after midnight still belong to Raviwara.

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: Mesha gives Vaishakha. The Sun enters Vrishabha on 14 May, inside the month. The next new moon, 11 Jun, finds it in Vrishabha and begins Jyeshtha.

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 11 Jun, with the Sun in Vrishabha, begins Jyeshtha. Until then this Krishna paksha reads Jyeshtha here, and Vaishakha in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 15 Mar 1972, 08:34 Wed. Since then the Sun has moved 85.6° round the stars. Vikram Samvat numbers that year 2029; Shaka Samvat numbers it 1894.
