Panchang in Davinópolis, Maranhão, Brazil Fri 11 Oct 2030

Purnima follows the tithi at sunrise. Purnima runs from 07:10 on Thu 10 Oct to 07:46 on Fri 11 Oct, so it holds sunrise only on Fri 11 Oct, at 05:50. No text giving Purnima’s time was found; sunrise is Tithika’s convention.

Purnima: every date in Davinópolis

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, 05:50 here. Chaturdashi ended at 07:10 Thu, before it. Purnima ends at 07:46, when the lead reaches 180°. The lead passed 0° at the new moon of 27 Sep, so the Moon is waxing: Shukla paksha.

The night of Thu 10 Oct ran from sunset 18:02 Thu to sunrise 05:50, 11 h 48 m. Cut into 15 muhurtas of 47 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:50 to 18:02, splits into 8 choghadiyas of 1 h 31 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:02 to 05:49 Sat, splits into 8 choghadiyas of 1 h 28 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′. Revati spans 346°40′–360°00′; the Moon entered its pada 2 at 350°. It leaves at 19:31, for Ashwini.

Add the Sun's and the Moon's places among the stars: 173.8° + 352.9° = 526.7°, one full turn and 166.7°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 160°00′–173°20′ is the 13th, Vyaghata. It ends at 17:41, then Harshana.

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 ended at 19:24 Thu, when the lead reached 174°; Bava runs until 07:46.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:50 to 05:49 Sat, so the hours after midnight still belong to Shukrawara.

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: Kanya gives Ashwina. The Sun enters Tula on 17 Oct, inside the month. The next new moon, 26 Oct, finds it in Tula and begins Kartika.

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 27 Sep, with the Sun in Kanya, began Ashwina. This Shukla paksha reads Ashwina in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 2 Apr 2030, 19:02 Tue. Since then the Sun has moved 184.9° round the stars. Vikram Samvat numbers that year 2087; Shaka Samvat numbers it 1952.
