Panchang in Ipameri, Goiás, Brazil Sun 18 Sep 2016

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 192°–204° is the 17th, Krishna Dwitiya. A day takes the tithi in force at its sunrise, 06:05 here. Pratipada ended at 13:04 Sat, before it. Dwitiya ends at 09:51, when the lead reaches 204°. The lead passed 180° at the full moon of 16 Sep, so the Moon is waning: Krishna paksha.

The night of Sat 17 Sep ran from sunset 18:08 Sat to sunrise 06:05, 11 h 57 m. Cut into 15 muhurtas of 47 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:05 to 18:08, 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 night here, 18:08 to 06:04 Mon, 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 fixed stars divide the Moon's path into 27 nakshatras of 13°20′, each in 4 padas of 3°20′. Revati spans 346°40′–360°00′; the Moon entered its pada 3 at 353°20′. It leaves at 16:25, for Ashwini.

Add the Sun's and the Moon's places among the stars: 151.8° + 353.6° = 505.4°, one full turn and 145.4°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 133°20′–146°40′ is the 11th, Vriddhi. It ends at 08:01, then Dhruva.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Dwitiya is Taitila and the second Garaja. Taitila ended at 23:28 Sat, when the lead reached 198°; Garaja runs until 09:51.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:05 to 06:04 Mon, so the hours after midnight still belong to Raviwara.

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: Simha gives Bhadrapada. The Sun enters Kanya on 16 Sep, inside the month. The next new moon, 30 Sep, finds it in Kanya and begins Ashwina.

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 30 Sep, with the Sun in Kanya, begins Ashwina. Until then this Krishna paksha reads Ashwina here, and Bhadrapada in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 7 Apr 2016, 08:23 Thu. Since then the Sun has moved 157.8° round the stars. Vikram Samvat numbers that year 2073; Shaka Samvat numbers it 1938.
