Panchang in Sevan, Gegharkunik, Armenia Tue 7 Jun 1921

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, 04:29 here. Amavasya ended at 09:14 Mon, before it. Pratipada ends at 06:13, when the lead reaches 12°. The lead passed 0° at the new moon of 6 Jun, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise. Dwitiya began at 06:13 and ended at 03:00 Wed, between the sunrises of 04:29 and 04:29 Wed. Tuesday reads Pratipada and Wednesday reads Tritiya: Dwitiya is a kshaya tithi here.

The night of Mon 6 Jun ran from sunset 19:27 Mon to sunrise 04:29, 9 h 2 m. Cut into 15 muhurtas of 36 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 04:29 to 19:27, splits into 8 choghadiyas of 1 h 52 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 19:27 to 04:29 Wed, splits into 8 choghadiyas of 1 h 7 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′. Mrigashira spans 53°20′–66°40′; the Moon entered its pada 4 at 63°20′. It leaves at 08:50, for Ardra.

Add the Sun's and the Moon's places among the stars: 53° + 64° = 117°. The sum, cut into 27 parts of 13°20′, gives the yoga: 106°40′–120°00′ is the 9th, Shula. It ends at 09:06, then Ganda.

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 ended at 19:46 Mon, when the lead reached 6°; Bava runs until 06:13.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 04:29 to 04:29 Wed, so the hours after midnight still belong to Mangalawara.

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: Vrishabha gives Jyeshtha. The Sun enters Mithuna on 14 Jun, inside the month. The next new moon, 5 Jul, finds it in Mithuna and begins Ashadha.

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 6 Jun, with the Sun in Vrishabha, began Jyeshtha. This Shukla paksha reads Jyeshtha in both counts.

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 57.8° round the stars. Vikram Samvat numbers that year 1978; Shaka Samvat numbers it 1843.
