Panchang in Ipameri, Goiás, Brazil Thu 22 May 1902

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, 06:32 here. Chaturdashi ended at 05:20 Wed, before it. Purnima ends at 07:45, when the lead reaches 180°. The lead passed 0° at the new moon of 7 May, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise. Purnima began at 05:20 Wed, before sunrise at 06:32 Wed, and ends at 07:45, after the next sunrise at 06:32. Both days read Purnima: it is a vriddhi tithi here.

The night of Wed 21 May ran from sunset 17:46 Wed to sunrise 06:32, 12 h 47 m. Cut into 15 muhurtas of 51 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:32 to 17:45, splits into 8 choghadiyas of 1 h 24 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 06:32 Fri, splits into 8 choghadiyas of 1 h 35 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 2 at 216°40′. It leaves at 01:32 Fri, for Jyeshtha.

Add the Sun's and the Moon's places among the stars: 37.9° + 217.3° = 255.2°. The sum, cut into 27 parts of 13°20′, gives the yoga: 253°20′–266°40′ is the 20th, Shiva. It ends at 04:09 Fri, 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 ended at 18:32 Wed, when the lead reached 174°; Bava runs until 07:45.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:32 to 06:32 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: Mesha gives Vaishakha. The Sun enters Vrishabha on 14 May, inside the month. The next new moon, 6 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 7 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: 8 Apr 1902, 10:49 Tue. Since then the Sun has moved 42.6° round the stars. Vikram Samvat numbers that year 1959; Shaka Samvat numbers it 1824.
