Panchang in Davinópolis, Maranhão, Brazil Thu 16 Dec 1999

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 84°–96° is the 8th, Shukla Ashtami. A day takes the tithi in force at its sunrise, 06:51 here. Saptami ended at 10:46 Wed, before it. Ashtami ends at 10:41, when the lead reaches 96°. The lead passed 0° at the new moon of 7 Dec, so the Moon is waxing: Shukla paksha.

The night of Wed 15 Dec ran from sunset 19:17 Wed to sunrise 06:51, 11 h 34 m. Cut into 15 muhurtas of 46 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:51 to 19:18, splits into 8 choghadiyas of 1 h 33 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 19:18 to 06:52 Fri, splits into 8 choghadiyas of 1 h 26 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′. Uttara Bhadrapada spans 333°20′–346°40′; the Moon entered its pada 1 at 333°20′. It leaves at 05:16 Fri, for Revati.

Add the Sun's and the Moon's places among the stars: 240.1° + 334.1° = 574.2°, one full turn and 214.2°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 213°20′–226°40′ is the 17th, Vyatipata. It ends at 03:34 Fri, then Variyana.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Ashtami is Vishti and the second Bava. Vishti ended at 22:50 Wed, when the lead reached 90°; Bava runs until 10:41.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:51 to 06:52 Fri, so the hours after midnight still belong to Guruwara.

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: Vrishchika gives Margashirsha. The Sun enters Dhanu on 16 Dec, inside the month. The next new moon, 6 Jan, finds it in Dhanu and begins Pausha.

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 7 Dec, with the Sun in Vrishchika, began Margashirsha. This Shukla paksha reads Margashirsha in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 17 Mar 1999, 15:47 Wed. Since then the Sun has moved 267.2° round the stars. Vikram Samvat numbers that year 2056; Shaka Samvat numbers it 1921.
