Panchang in Ipameri, Goiás, Brazil Sat 8 Dec 2007

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 336°–348° is the 29th, Krishna Chaturdashi. A day takes the tithi in force at its sunrise, 06:29 here. Trayodashi ended at 11:07 Fri, before it. Chaturdashi ends at 13:31, when the lead reaches 348°. The lead passed 180° at the full moon of 24 Nov, so the Moon is waning: Krishna paksha.

The night of Fri 7 Dec ran from sunset 19:38 Fri to sunrise 06:29, 10 h 51 m. Cut into 15 muhurtas of 43 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:29 to 19:39, splits into 8 choghadiyas of 1 h 38 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 19:39 to 06:30 Sun, splits into 8 choghadiyas of 1 h 21 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′. Anuradha spans 213°20′–226°40′; the Moon entered its pada 2 at 216°40′. It leaves at 02:29 Sun, for Jyeshtha.

Add the Sun's and the Moon's places among the stars: 231.9° + 216.7° = 448.6°, one full turn and 88.6°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 80°00′–93°20′ is the 7th, Sukarma. It ends at 15:18, then Dhriti.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Chaturdashi is Vishti and the second Shakuni. Vishti ended at 00:21, when the lead reached 342°; Shakuni runs until 13:31.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:29 to 06:30 Sun, so the hours after midnight still belong to Shaniwara.

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: Tula gives Kartika. The Sun enters Vrishchika on 16 Nov, inside the month. The next new moon, 9 Dec, finds it in Vrishchika and begins Margashirsha.

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 9 Dec, with the Sun in Vrishchika, begins Margashirsha. Until then this Krishna paksha reads Margashirsha here, and Kartika in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 18 Mar 2007, 23:42 Sun. Since then the Sun has moved 257.7° round the stars. Vikram Samvat numbers that year 2064; Shaka Samvat numbers it 1929.
