Panchang in Ipameri, Goiás, Brazil Thu 17 Feb 2011

Purnima follows the tithi at sunrise. Purnima begins at 10:04 on Thu 17 Feb, after that sunrise, and ends at 06:35 on Fri 18 Feb, before the next: it holds no sunrise. A tithi that holds no sunrise is kept on the day it is current: Thu 17 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, 07:07 here. Trayodashi ended at 13:09 Wed, before it. Chaturdashi ends at 10:04, when the lead reaches 168°. The lead passed 0° at the new moon of 3 Feb, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise. Purnima began at 10:04 and ended at 06:35 Fri, between the sunrises of 07:07 and 07:08 Fri. Thursday reads Chaturdashi and Friday reads Pratipada: Purnima is a kshaya tithi here.

The night of Wed 16 Feb ran from sunset 19:46 Wed to sunrise 07:07, 11 h 21 m. Cut into 15 muhurtas of 45 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 07:07 to 19:45, splits into 8 choghadiyas of 1 h 34 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 19:45 to 07:08 Fri, splits into 8 choghadiyas of 1 h 25 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′. Ashlesha spans 106°40′–120°00′; the Moon entered its pada 2 at 110°. It leaves at 22:08, for Magha.

Add the Sun's and the Moon's places among the stars: 304.3° + 110.6° = 414.9°, one full turn and 54.9°. 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 00:41 Fri, then Atiganda.

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 23:40 Wed, when the lead reached 162°; Vanija runs until 10:04.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 07:07 to 07:08 Fri, so the hours after midnight still belong to Guruwara.

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 13 Feb, inside the month. The next new moon, 4 Mar, 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 3 Feb, 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: 15 Mar 2010, 18:01 Mon. Since then the Sun has moved 333.1° round the stars. Vikram Samvat numbers that year 2067; Shaka Samvat numbers it 1932.
