Panchang in Ipameri, Goiás, Brazil Sat 26 May 1945

Buddha Purnima follows the tithi at sunrise. Purnima runs from 21:07 on Fri 25 May to 22:48 on Sat 26 May, so it holds sunrise only on Sat 26 May, at 06:34. No text giving Buddha 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, 06:34 here. Chaturdashi ended at 21:07 Fri, before it. Purnima ends at 22:48, when the lead reaches 180°. The lead passed 0° at the new moon of 11 May, so the Moon is waxing: Shukla paksha.

The night of Fri 25 May ran from sunset 17:45 Fri to sunrise 06:34, 12 h 49 m. Cut into 15 muhurtas of 51 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:34 to 17:45, 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 night here, 17:45 to 06:34 Sun, 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 fixed stars divide the Moon's path into 27 nakshatras of 13°20′, each in 4 padas of 3°20′. Anuradha spans 213°20′–226°40′; the Moon entered its pada 1 at 213°20′. It leaves at 07:19 Sun, for Jyeshtha.

Add the Sun's and the Moon's places among the stars: 41.7° + 214.1° = 255.8°. The sum, cut into 27 parts of 13°20′, gives the yoga: 253°20′–266°40′ is the 20th, Shiva. It ends at 02:30 Sun, then Siddha.

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 10:00, when the lead reaches 174°; Bava until 22:48.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:34 to 06:34 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: Mesha gives Vaishakha. The Sun enters Vrishabha on 14 May, inside the month. The next new moon, 10 Jun, finds it in Vrishabha and begins Jyeshtha.

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 11 May, with the Sun in Mesha, began Vaishakha. This Shukla paksha reads Vaishakha in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 14 Mar 1945, 00:50 Wed. Since then the Sun has moved 71.6° round the stars. Vikram Samvat numbers that year 2002; Shaka Samvat numbers it 1867.
