Panchang in Ipameri, Goiás, Brazil Sun 5 Apr 1964

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 264°–276° is the 23rd, Krishna Ashtami. A day takes the tithi in force at its sunrise, 06:19 here. Saptami ended at 13:38 Sat, before it. Ashtami ends at 15:43, when the lead reaches 276°. The lead passed 180° at the full moon of 27 Mar, so the Moon is waning: Krishna paksha.

The night of Sat 4 Apr ran from sunset 18:11 Sat to sunrise 06:19, 12 h 8 m. Cut into 15 muhurtas of 48 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:19 to 18:10, splits into 8 choghadiyas of 1 h 28 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:10 to 06:20 Mon, 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 fixed stars divide the Moon's path into 27 nakshatras of 13°20′, each in 4 padas of 3°20′. Purva Ashadha spans 253°20′–266°40′; the Moon entered its pada 4 at 263°20′. It leaves at 11:47, for Uttara Ashadha.

Add the Sun's and the Moon's places among the stars: 352.3° + 263.9° = 616.2°, one full turn and 256.2°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 253°20′–266°40′ is the 20th, Shiva. It ends at 01:29 Mon, then Siddha.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Ashtami is Balava and the second Kaulava. Balava ended at 02:44, when the lead reached 270°; Kaulava runs until 15:43.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:19 to 06:20 Mon, so the hours after midnight still belong to Raviwara.

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 12 Apr, with the Sun in Meena, begins Chaitra (Adhik). Until then this Krishna paksha reads Chaitra (Adhik) here, and Chaitra (Adhik) in the amanta count.

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 22.1° round the stars. Vikram Samvat numbers that year 2021; Shaka Samvat numbers it 1886.
