Panchang in Ipameri, Goiás, Brazil Fri 18 May 1923

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 24°–36° is the 3rd, Shukla Tritiya. A day takes the tithi in force at its sunrise, 06:31 here. Dwitiya ended at 22:56 Thu, before it. Tritiya ends at 00:02 Sat, when the lead reaches 36°. The lead passed 0° at the new moon of 15 May, so the Moon is waxing: Shukla paksha.

The night of Thu 17 May ran from sunset 17:47 Thu to sunrise 06:31, 12 h 44 m. Cut into 15 muhurtas of 50 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:31 to 17:46, 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, 17:46 to 06:31 Sat, 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′. Mrigashira spans 53°20′–66°40′; the Moon entered its pada 3 at 60°. It leaves at 16:59, for Ardra.

Add the Sun's and the Moon's places among the stars: 33.6° + 61.2° = 94.8°. The sum, cut into 27 parts of 13°20′, gives the yoga: 93°20′–106°40′ is the 8th, Dhriti. It ends at 03:34 Sat, then Shula.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Tritiya is Taitila and the second Garaja. Taitila runs until 11:32, when the lead reaches 30°; Garaja until 00:02 Sat.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:31 to 06:31 Sat, so the hours after midnight still belong to Shukrawara.

A month normally holds one sankranti, the Sun's entry into a new rashi. From 15 May 19:38 Tue to 14 Jun 09:41 Thu the Sun stayed in Vrishabha, entering Mithuna at 14 Jun 18:42 Thu, after the new moon. A month with no sankranti is Adhika Jyeshtha, before Jyeshtha itself.

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 15 May, with the Sun in Vrishabha, began Jyeshtha (Adhik). This Shukla paksha reads Jyeshtha (Adhik) in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 17 Mar 1923, 09:51 Sat. Since then the Sun has moved 60.5° round the stars. Vikram Samvat numbers that year 1980; Shaka Samvat numbers it 1845.
