Panchang in Sevan, Gegharkunik, Armenia Sun 20 Oct 2013

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, 07:16 here. Pratipada ended at 03:42, before it. Dwitiya ends at 04:22 Mon, when the lead reaches 204°. The lead passed 180° at the full moon of 19 Oct, so the Moon is waning: Krishna paksha.

The night of Sat 19 Oct ran from sunset 18:14 Sat to sunrise 07:16, 13 h 2 m. Cut into 15 muhurtas of 52 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 07:16 to 18:12, splits into 8 choghadiyas of 1 h 22 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:12 to 07:17 Mon, 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 fixed stars divide the Moon's path into 27 nakshatras of 13°20′, each in 4 padas of 3°20′. Bharani spans 13°20′–26°40′; the Moon entered its pada 1 at 13°20′. It leaves at 02:21 Mon, for Krittika.

Add the Sun's and the Moon's places among the stars: 182.8° + 16.6° = 199.4°. The sum, cut into 27 parts of 13°20′, gives the yoga: 186°40′–200°00′ is the 15th, Vajra. It ends at 08:15, then Siddhi.

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 runs until 15:58, when the lead reaches 198°; Garaja until 04:22 Mon.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 07:16 to 07:17 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: Kanya gives Ashwina. The Sun enters Tula on 17 Oct, inside the month. The next new moon, 3 Nov, finds it in Tula and begins Kartika.

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 3 Nov, with the Sun in Tula, begins Kartika. Until then this Krishna paksha reads Kartika here, and Ashwina in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 10 Apr 2013, 13:35 Wed. Since then the Sun has moved 186.2° round the stars. Vikram Samvat numbers that year 2070; Shaka Samvat numbers it 1935.
