Panchang in Sevan, Gegharkunik, Armenia Sun 25 Nov 1973

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 0°–12° is the 1st, Shukla Pratipada. A day takes the tithi in force at its sunrise, 07:57 here. Amavasya ended at 23:55 Sat, before it. Pratipada ends at 01:59 Mon, when the lead reaches 12°. The lead passed 0° at the new moon of 24 Nov, so the Moon is waxing: Shukla paksha.

The night of Sat 24 Nov ran from sunset 17:36 Sat to sunrise 07:57, 14 h 21 m. Cut into 15 muhurtas of 57 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 07:57 to 17:36, splits into 8 choghadiyas of 1 h 12 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 07:58 Mon, splits into 8 choghadiyas of 1 h 47 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′. Anuradha spans 213°20′–226°40′; the Moon entered its pada 3 at 220°. It leaves at 15:19, for Jyeshtha.

Add the Sun's and the Moon's places among the stars: 219.2° + 223° = 442.2°, one full turn and 82.2°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 80°00′–93°20′ is the 7th, Sukarma. It ends at 04:26 Mon, then Dhriti.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Pratipada is Kinstughna and the second Bava. Kinstughna runs until 12:54, when the lead reaches 6°; Bava until 01:59 Mon.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 07:57 to 07:58 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 15 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 Nov, 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: 3 Apr 1973, 15:45 Tue. Since then the Sun has moved 229.1° round the stars. Vikram Samvat numbers that year 2030; Shaka Samvat numbers it 1895.
