Panchang in Ipameri, Goiás, Brazil Thu 19 Mar 1964

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 60°–72° is the 6th, Shukla Shashthi. A day takes the tithi in force at its sunrise, 06:16 here. Panchami ended at 11:06 Wed, before it. Shashthi ends at 08:45, when the lead reaches 72°. The lead passed 0° at the new moon of 13 Mar, so the Moon is waxing: Shukla paksha.

The night of Wed 18 Mar ran from sunset 18:25 Wed to sunrise 06:16, 11 h 51 m. Cut into 15 muhurtas of 47 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:16 to 18:24, 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, 18:24 to 06:16 Fri, splits into 8 choghadiyas of 1 h 29 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′. Rohini spans 40°00′–53°20′; the Moon entered its pada 2 at 43°20′. It leaves at 18:30, for Mrigashira.

Add the Sun's and the Moon's places among the stars: 335.5° + 46.1° = 381.6°, one full turn and 21.6°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 13°20′–26°40′ is the 2nd, Priti. It ends at 14:21, then Ayushmana.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Shashthi is Kaulava and the second Taitila. Kaulava ended at 21:54 Wed, when the lead reached 66°; Taitila runs until 08:45.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:16 to 06:16 Fri, so the hours after midnight still belong to Guruwara.

A month normally holds one sankranti, the Sun's entry into a new rashi. From 13 Mar 23:13 Fri to 12 Apr 09:37 Sun the Sun stayed in Meena, entering Mesha at 13 Apr 03:22 Mon, after the new moon. A month with no sankranti is Adhika Chaitra, before Chaitra 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 13 Mar, with the Sun in Meena, began Chaitra (Adhik). This Shukla paksha reads Chaitra (Adhik) in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 13 Mar 1964, 23:13 Fri. Since then the Sun has moved 5.3° round the stars. Vikram Samvat numbers that year 2021; Shaka Samvat numbers it 1886.
