Panchang in Ipameri, Goiás, Brazil Tue 19 Nov 1968

Amavasya follows the tithi at sunrise. Amavasya begins at 08:38 on Tue 19 Nov, after that sunrise, and ends at 05:01 on Wed 20 Nov, before the next: it holds no sunrise. A tithi that holds no sunrise is kept on the day it is current: Tue 19 Nov. No text giving Amavasya’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: 336°–348° is the 29th, Krishna Chaturdashi. A day takes the tithi in force at its sunrise, 05:28 here. Trayodashi ended at 11:55 Mon, before it. Chaturdashi ends at 08:38, when the lead reaches 348°. The lead passed 180° at the full moon of 5 Nov, so the Moon is waning: Krishna paksha.

A day takes the tithi in force at its sunrise. Amavasya began at 08:38 and ended at 05:01 Wed, between the sunrises of 05:28 and 05:28 Wed. Tuesday reads Chaturdashi and Wednesday reads Pratipada: Amavasya is a kshaya tithi here.

The night of Mon 18 Nov ran from sunset 18:27 Mon to sunrise 05:28, 11 h 1 m. Cut into 15 muhurtas of 44 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:28 to 18:28, 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 night here, 18:28 to 05:28 Wed, splits into 8 choghadiyas of 1 h 22 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′. Swati spans 186°40′–200°00′; the Moon entered its pada 4 at 196°40′. It leaves at 05:46, for Vishakha.

Add the Sun's and the Moon's places among the stars: 213.7° + 199.8° = 413.5°, one full turn and 53.5°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 53°20′–66°40′ is the 5th, Shobhana. It ends at 01:07 Wed, then Atiganda.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Chaturdashi is Vishti and the second Shakuni. Vishti ended at 22:20 Mon, when the lead reached 342°; Shakuni runs until 08:38.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:28 to 05:28 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: Tula gives Kartika. The Sun enters Vrishchika on 15 Nov, inside the month. The next new moon, 20 Nov, finds it in Vrishchika and begins Margashirsha.

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 Nov, with the Sun in Vrishchika, begins Margashirsha. Until then this Krishna paksha reads Margashirsha here, and Kartika in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 28 Mar 1968, 19:47 Thu. Since then the Sun has moved 228.8° round the stars. Vikram Samvat numbers that year 2025; Shaka Samvat numbers it 1890.
