Panchang in Ipameri, Goiás, Brazil Tue 3 Feb 1920

Purnima follows the tithi at sunrise. Purnima begins at 08:18 on Tue 3 Feb, after that sunrise, and ends at 05:42 on Wed 4 Feb, before the next: it holds no sunrise. A tithi that holds no sunrise is kept on the day it is current: Tue 3 Feb. No text giving Purnima’s time was found; sunrise is Tithika’s convention.

Purnima: every date in Ipameri

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 156°–168° is the 14th, Shukla Chaturdashi. A day takes the tithi in force at its sunrise, 06:00 here. Trayodashi ended at 11:08 Mon, before it. Chaturdashi ends at 08:18, when the lead reaches 168°. The lead passed 0° at the new moon of 21 Jan, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise. Purnima began at 08:18 and ended at 05:42 Wed, between the sunrises of 06:00 and 06:01 Wed. Tuesday reads Chaturdashi and Wednesday reads Pratipada: Purnima is a kshaya tithi here.

The night of Mon 2 Feb ran from sunset 18:52 Mon to sunrise 06:00, 11 h 8 m. Cut into 15 muhurtas of 44 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:00 to 18:52, splits into 8 choghadiyas of 1 h 36 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:52 to 06:01 Wed, 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 fixed stars divide the Moon's path into 27 nakshatras of 13°20′, each in 4 padas of 3°20′. Pushya spans 93°20′–106°40′; the Moon entered its pada 2 at 96°40′. It leaves at 21:38, for Ashlesha.

Add the Sun's and the Moon's places among the stars: 290.5° + 97.2° = 387.7°, one full turn and 27.7°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 26°40′–40°00′ is the 3rd, Ayushmana. It ends at 01:00 Wed, then Saubhagya.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Chaturdashi is Garaja and the second Vanija. Garaja ended at 21:42 Mon, when the lead reached 162°; Vanija runs until 08:18.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:00 to 06:01 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: Makara gives Magha. The Sun enters Kumbha on 12 Feb, inside the month. The next new moon, 19 Feb, finds it in Kumbha and begins Phalguna.

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 21 Jan, with the Sun in Makara, began Magha. This Shukla paksha reads Magha in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 31 Mar 1919, 18:04 Mon. Since then the Sun has moved 303.1° round the stars. Vikram Samvat numbers that year 1976; Shaka Samvat numbers it 1841.
