Panchang in Ipameri, Goiás, Brazil Sat 2 Feb 2064

Purnima follows the tithi at sunrise. Purnima runs from 21:41 on Fri 1 Feb to 18:37 on Sat 2 Feb, so it holds sunrise only on Sat 2 Feb, at 06:00. 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: 168°–180° is the 15th, Shukla Purnima. A day takes the tithi in force at its sunrise, 06:00 here. Chaturdashi ended at 21:41 Fri, before it. Purnima ends at 18:37, when the lead reaches 180°. The lead passed 0° at the new moon of 18 Jan, so the Moon is waxing: Shukla paksha.

The night of Fri 1 Feb ran from sunset 18:52 Fri 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 Sun, 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 3 at 100°. It leaves at 14:43, for Ashlesha.

Add the Sun's and the Moon's places among the stars: 288.5° + 101.3° = 389.8°, one full turn and 29.8°. 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 21:24, then Saubhagya.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Purnima is Vishti and the second Bava. Vishti runs until 08:11, when the lead reaches 174°; Bava until 18:37.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:00 to 06:01 Sun, so the hours after midnight still belong to Shaniwara.

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, 17 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 18 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: 29 Mar 2063, 21:50 Thu. Since then the Sun has moved 303.9° round the stars. Vikram Samvat numbers that year 2120; Shaka Samvat numbers it 1985.
