Panchang in Sevan, Gegharkunik, Armenia Sun 18 Dec 2011

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 264°–276° is the 23rd, Krishna Ashtami. A day takes the tithi in force at its sunrise, 08:17 here. Saptami ended at 17:39 Sat, before it. Ashtami ends at 15:50, when the lead reaches 276°. The lead passed 180° at the full moon of 10 Dec, so the Moon is waning: Krishna paksha.

The night of Sat 17 Dec ran from sunset 17:34 Sat to sunrise 08:17, 14 h 43 m. Cut into 15 muhurtas of 58 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 08:17 to 17:34, splits into 8 choghadiyas of 1 h 9 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 17:34 to 08:18 Mon, splits into 8 choghadiyas of 1 h 50 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 Phalguni spans 146°40′–160°00′; the Moon entered its pada 3 at 153°20′. It leaves at 18:57, for Hasta.

Add the Sun's and the Moon's places among the stars: 241.8° + 153.7° = 395.5°, one full turn and 35.5°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 26°40′–40°00′ is the 3rd, Ayushmana. It ends at 15:18, then Saubhagya.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Ashtami is Balava and the second Kaulava. Balava ended at 04:47, when the lead reached 270°; Kaulava runs until 15:50.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 08:17 to 08:18 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: Vrishchika gives Margashirsha. The Sun enters Dhanu on 16 Dec, inside the month. The next new moon, 24 Dec, 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 24 Dec, 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: 3 Apr 2011, 19:32 Sun. Since then the Sun has moved 252.3° round the stars. Vikram Samvat numbers that year 2068; Shaka Samvat numbers it 1933.
