Panchang in Sevan, Gegharkunik, Armenia Sun 14 Apr 1940

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 60°–72° is the 6th, Shukla Shashthi. A day takes the tithi in force at its sunrise, 05:23 here. Panchami ended at 06:12 Sat, before it. Shashthi ends at 06:04, when the lead reaches 72°. The lead passed 0° at the new moon of 7 Apr, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise. Saptami began at 06:04 and ended at 05:20 Mon, between the sunrises of 05:23 and 05:22 Mon. Sunday reads Shashthi and Monday reads Ashtami: Saptami is a kshaya tithi here.

The night of Sat 13 Apr ran from sunset 18:36 Sat to sunrise 05:23, 10 h 47 m. Cut into 15 muhurtas of 43 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:23 to 18:37, splits into 8 choghadiyas of 1 h 39 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:37 to 05:22 Mon, splits into 8 choghadiyas of 1 h 20 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 2 at 70°. It leaves at 18:43, for Punarvasu.

Add the Sun's and the Moon's places among the stars: 1° + 72.6° = 73.6°. The sum, cut into 27 parts of 13°20′, gives the yoga: 66°40′–80°00′ is the 6th, Atiganda. It ends at 16:11, then Sukarma.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Shashthi is Kaulava and the second Taitila. Kaulava ended at 18:13 Sat, when the lead reached 66°; Taitila runs until 06:04.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:23 to 05:22 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: Meena gives Chaitra. The Sun enters Mesha on 13 Apr, inside the month. The next new moon, 7 May, finds it in Mesha and begins Vaishakha.

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 7 Apr, with the Sun in Meena, began Chaitra. This Shukla paksha reads Chaitra in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 7 Apr 1940, 23:18 Sun. Since then the Sun has moved 6.2° round the stars. Vikram Samvat numbers that year 1997; Shaka Samvat numbers it 1862.
