Panchang in Sevan, Gegharkunik, Armenia Wed 17 Dec 1975

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 156°–168° is the 14th, Shukla Chaturdashi. A day takes the tithi in force at its sunrise, 08:17 here. Trayodashi ended at 18:11 Tue, before it. Chaturdashi ends at 18:43, when the lead reaches 168°. The lead passed 0° at the new moon of 3 Dec, so the Moon is waxing: Shukla paksha.

The night of Tue 16 Dec ran from sunset 17:34 Tue 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 08:17 Thu, 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′. Rohini spans 40°00′–53°20′; the Moon entered its pada 2 at 43°20′. It leaves at 01:48 Thu, for Mrigashira.

Add the Sun's and the Moon's places among the stars: 241.1° + 43.9° = 285°. The sum, cut into 27 parts of 13°20′, gives the yoga: 280°00′–293°20′ is the 22nd, Sadhya. It ends at 22:42, then Shubha.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Chaturdashi is Garaja and the second Vanija. Garaja ended at 06:32, when the lead reached 162°; Vanija runs until 18:43.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 08:17 to 08:17 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, 1 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 3 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: 11 Apr 1975, 20:38 Fri. Since then the Sun has moved 243.4° round the stars. Vikram Samvat numbers that year 2032; Shaka Samvat numbers it 1897.
