Panchang in Ipameri, Goiás, Brazil Sat 31 Mar 1945

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 204°–216° is the 18th, Krishna Tritiya. A day takes the tithi in force at its sunrise, 06:18 here. Dwitiya ended at 19:37 Fri, before it. Tritiya ends at 21:58, when the lead reaches 216°. The lead passed 180° at the full moon of 28 Mar, so the Moon is waning: Krishna paksha.

The night of Fri 30 Mar ran from sunset 18:15 Fri to sunrise 06:18, 12 h 3 m. Cut into 15 muhurtas of 48 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:18 to 18:15, 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 night here, 18:15 to 06:19 Sun, splits into 8 choghadiyas of 1 h 30 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′. Swati spans 186°40′–200°00′; the Moon entered its pada 3 at 193°20′. It leaves at 14:13, for Vishakha.

Add the Sun's and the Moon's places among the stars: 347.2° + 196.1° = 543.3°, one full turn and 183.3°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 173°20′–186°40′ is the 14th, Harshana. It ends at 12:37, then Vajra.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Tritiya is Vanija and the second Vishti. Vanija runs until 08:48, when the lead reaches 210°; Vishti until 21:58.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:18 to 06:19 Sun, so the hours after midnight still belong to Shaniwara.

A month normally holds one sankranti, the Sun's entry into a new rashi. From 14 Mar 00:50 Wed to 12 Apr 09:29 Thu the Sun stayed in Meena, entering Mesha at 13 Apr 06:29 Fri, 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: 14 Mar 1945, 00:50 Wed. Since then the Sun has moved 17.1° round the stars. Vikram Samvat numbers that year 2002; Shaka Samvat numbers it 1867.
