Panchang in Sevan, Gegharkunik, Armenia Fri 13 Dec 1985

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 12°–24° is the 2nd, Shukla Dwitiya. A day takes the tithi in force at its sunrise, 08:14 here. Pratipada ended at 01:30, before it. Dwitiya ends at 22:27, when the lead reaches 24°. The lead passed 0° at the new moon of 12 Dec, so the Moon is waxing: Shukla paksha.

The night of Thu 12 Dec ran from sunset 17:33 Thu to sunrise 08:14, 14 h 41 m. Cut into 15 muhurtas of 58 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 08:14 to 17:33, 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, 17:33 to 08:15 Sat, 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′. Mula spans 240°00′–253°20′; the Moon entered its pada 4 at 250°. It leaves at 08:15, for Purva Ashadha.

Add the Sun's and the Moon's places among the stars: 237.4° + 253.3° = 490.7°, one full turn and 130.7°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 120°00′–133°20′ is the 10th, Ganda. It ends at 12:08, then Vriddhi.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Dwitiya is Balava and the second Kaulava. Balava runs until 11:55, when the lead reaches 18°; Kaulava until 22:27.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 08:14 to 08:15 Sat, so the hours after midnight still belong to Shukrawara.

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 15 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 12 Dec, with the Sun in Vrishchika, began Margashirsha. This Shukla paksha reads Margashirsha in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 21 Mar 1985, 15:58 Thu. Since then the Sun has moved 260.2° round the stars. Vikram Samvat numbers that year 2042; Shaka Samvat numbers it 1907.
