Panchang in Sevan, Gegharkunik, Armenia Wed 28 Dec 1921

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 336°–348° is the 29th, Krishna Chaturdashi. A day takes the tithi in force at its sunrise, 07:22 here. Trayodashi ended at 07:13 Tue, before it. Chaturdashi ends at 07:44, when the lead reaches 348°. The lead passed 180° at the full moon of 15 Dec, so the Moon is waning: Krishna paksha.

A day takes the tithi in force at its sunrise. Chaturdashi began at 07:13 Tue, before sunrise at 07:22 Tue, and ends at 07:44, after the next sunrise at 07:22. Both days read Chaturdashi: it is a vriddhi tithi here.

The night of Tue 27 Dec ran from sunset 16:39 Tue to sunrise 07:22, 14 h 43 m. Cut into 15 muhurtas of 58 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 07:22 to 16:40, 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, 16:40 to 07:22 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′. Mula spans 240°00′–253°20′; the Moon entered its pada 1 at 240°. It leaves at 06:57 Thu, for Purva Ashadha.

Add the Sun's and the Moon's places among the stars: 253.1° + 241° = 494.1°, one full turn and 134.1°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 133°20′–146°40′ is the 11th, Vriddhi. It ends at 05:30 Thu, then Dhruva.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Chaturdashi is Vishti and the second Shakuni. Vishti ended at 19:25 Tue, when the lead reached 342°; Shakuni runs until 07:44.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 07:22 to 07:22 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 15 Dec, inside the month. The next new moon, 29 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 29 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: 8 Apr 1921, 12:04 Fri. Since then the Sun has moved 257.9° round the stars. Vikram Samvat numbers that year 1978; Shaka Samvat numbers it 1843.
