Panchang in Curchorem, Goa Wed 6 Jan 2016

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 312°–324° is the 27th, Krishna Dwadashi. A day takes the tithi in force at its sunrise, 07:01 here. Ekadashi ended at 06:54, before it. Dwadashi ends at 07:54 Thu, when the lead reaches 324°. The lead passed 180° at the full moon of 25 Dec, so the Moon is waning: Krishna paksha.

A day takes the tithi in force at its sunrise. Dwadashi began at 06:54, before sunrise at 07:01, and ends at 07:54 Thu, after the next sunrise at 07:01 Thu. Both days read Dwadashi: it is a vriddhi tithi here.

The night of Tue 5 Jan ran from sunset 18:16 Tue to sunrise 07:01, 12 h 45 m. Cut into 15 muhurtas of 51 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 07:01 to 18:16, splits into 8 choghadiyas of 1 h 24 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:16 to 07:01 Thu, splits into 8 choghadiyas of 1 h 35 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′. Vishakha spans 200°00′–213°20′; the Moon entered its pada 4 at 210°. It leaves at 07:26, for Anuradha.

Add the Sun's and the Moon's places among the stars: 261.1° + 213.1° = 474.2°, one full turn and 114.2°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 106°40′–120°00′ is the 9th, Shula. It ends at 17:23, then Ganda.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Dwadashi is Kaulava and the second Taitila. Kaulava runs until 19:29, when the lead reaches 318°; Taitila until 07:54 Thu.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 07:01 to 07:01 Thu, so the hours after midnight still belong to Budhawara.

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, 10 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 10 Jan, with the Sun in Dhanu, begins Pausha. Until then this Krishna paksha reads Pausha here, and Margashirsha in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 20 Mar 2015, 15:06 Fri. Since then the Sun has moved 285.7° round the stars. Vikram Samvat numbers that year 2072; Shaka Samvat numbers it 1937.
