Panchang in Sevan, Gegharkunik, Armenia Thu 21 Dec 1972

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 180°–192° is the 16th, Krishna Pratipada. A day takes the tithi in force at its sunrise, 08:19 here. Purnima ended at 13:45 Wed, before it. Pratipada ends at 10:20, when the lead reaches 192°. The lead passed 180° at the full moon of 20 Dec, so the Moon is waning: Krishna paksha.

A day takes the tithi in force at its sunrise. Dwitiya began at 10:20 and ended at 07:17 Fri, between the sunrises of 08:19 and 08:20 Fri. Thursday reads Pratipada and Friday reads Tritiya: Dwitiya is a kshaya tithi here.

The night of Wed 20 Dec ran from sunset 17:35 Wed to sunrise 08:19, 14 h 44 m. Cut into 15 muhurtas of 58 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 08:19 to 17:36, 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, 17:36 to 08:20 Fri, 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′. Ardra spans 66°40′–80°00′; the Moon entered its pada 4 at 76°40′. It leaves at 13:32, for Punarvasu.

Add the Sun's and the Moon's places among the stars: 245.9° + 76.8° = 322.7°. The sum, cut into 27 parts of 13°20′, gives the yoga: 320°00′–333°20′ is the 25th, Brahma. It ends at 00:27 Fri, then Indra.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Pratipada is Balava and the second Kaulava. Balava ended at 00:00, when the lead reached 186°; Kaulava runs until 10:20.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 08:19 to 08:20 Fri, so the hours after midnight still belong to Guruwara.

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, 4 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 4 Jan, 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: 15 Mar 1972, 15:34 Wed. Since then the Sun has moved 274.4° round the stars. Vikram Samvat numbers that year 2029; Shaka Samvat numbers it 1894.
