Panchang in Sevan, Gegharkunik, Armenia Sat 14 Aug 1943

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 144°–156° is the 13th, Shukla Trayodashi. A day takes the tithi in force at its sunrise, 05:08 here. Dwadashi ended at 09:25 Fri, before it. Trayodashi ends at 05:58, when the lead reaches 156°. The lead passed 0° at the new moon of 1 Aug, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise. Chaturdashi began at 05:58 and ended at 02:18 Sun, between the sunrises of 05:08 and 05:09 Sun. Saturday reads Trayodashi and Sunday reads Purnima: Chaturdashi is a kshaya tithi here.

The night of Fri 13 Aug ran from sunset 19:01 Fri to sunrise 05:08, 10 h 7 m. Cut into 15 muhurtas of 40 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:08 to 19:00, splits into 8 choghadiyas of 1 h 44 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 19:00 to 05:09 Sun, splits into 8 choghadiyas of 1 h 16 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′. Uttara Ashadha spans 266°40′–280°00′; the Moon entered its pada 2 at 270°. It leaves at 16:28, for Shravana.

Add the Sun's and the Moon's places among the stars: 117.4° + 272.9° = 390.3°, one full turn and 30.3°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 26°40′–40°00′ is the 3rd, Ayushmana. It ends at 19:43, then Saubhagya.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Trayodashi is Kaulava and the second Taitila. Kaulava ended at 19:44 Fri, when the lead reached 150°; Taitila runs until 05:58.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:08 to 05:09 Sun, so the hours after midnight still belong to Shaniwara.

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: Karka gives Shravana. The Sun enters Simha on 16 Aug, inside the month. The next new moon, 30 Aug, finds it in Simha and begins Bhadrapada.

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 1 Aug, with the Sun in Karka, began Shravana. This Shukla paksha reads Shravana in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 5 Apr 1943, 00:52 Mon. Since then the Sun has moved 126.2° round the stars. Vikram Samvat numbers that year 2000; Shaka Samvat numbers it 1865.
