Panchang in Ipameri, Goiás, Brazil Tue 11 May 1937

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 0°–12° is the 1st, Shukla Pratipada. A day takes the tithi in force at its sunrise, 06:28 here. Amavasya ended at 10:17 Mon, before it. Pratipada ends at 06:31, when the lead reaches 12°. The lead passed 0° at the new moon of 10 May, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise. Dwitiya began at 06:31 and ended at 02:54 Wed, between the sunrises of 06:28 and 06:29 Wed. Tuesday reads Pratipada and Wednesday reads Tritiya: Dwitiya is a kshaya tithi here.

The night of Mon 10 May ran from sunset 17:49 Mon to sunrise 06:28, 12 h 39 m. Cut into 15 muhurtas of 50 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:28 to 17:49, 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 night here, 17:49 to 06:29 Wed, 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′. Krittika spans 26°40′–40°00′; the Moon entered its pada 4 at 36°40′. It leaves at 07:39, for Rohini.

Add the Sun's and the Moon's places among the stars: 27.3° + 39.3° = 66.6°. The sum, cut into 27 parts of 13°20′, gives the yoga: 53°20′–66°40′ is the 5th, Shobhana. It ends at 06:40, then Atiganda.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Pratipada is Kinstughna and the second Bava. Kinstughna ended at 20:23 Mon, when the lead reached 6°; Bava runs until 06:31.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:28 to 06:29 Wed, so the hours after midnight still belong to Mangalawara.

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, 8 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 10 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: 11 Apr 1937, 02:09 Sun. Since then the Sun has moved 29.4° round the stars. Vikram Samvat numbers that year 1994; Shaka Samvat numbers it 1859.
