Panchang in Sevan, Gegharkunik, Armenia Wed 31 Aug 1955

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, 05:25 here. Dwadashi ended at 09:50 Tue, before it. Trayodashi ends at 10:50, when the lead reaches 156°. The lead passed 0° at the new moon of 17 Aug, so the Moon is waxing: Shukla paksha.

The night of Tue 30 Aug ran from sunset 18:36 Tue to sunrise 05:25, 10 h 49 m. Cut into 15 muhurtas of 43 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:25 to 18:35, splits into 8 choghadiyas of 1 h 38 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:35 to 05:26 Thu, splits into 8 choghadiyas of 1 h 21 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′. Shravana spans 280°00′–293°20′; the Moon entered its pada 3 at 286°40′. It leaves at 17:20, for Dhanishtha.

Add the Sun's and the Moon's places among the stars: 133.7° + 287.1° = 420.8°, one full turn and 60.8°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 53°20′–66°40′ is the 5th, Shobhana. It ends at 15:53, then Atiganda.

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 22:25 Tue, when the lead reached 150°; Taitila runs until 10:50.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:25 to 05:26 Thu, so the hours after midnight still belong to Budhawara.

A month normally holds one sankranti, the Sun's entry into a new rashi. From 17 Aug 22:58 Wed to 16 Sep 09:19 Fri the Sun stayed in Simha, entering Kanya at 17 Sep 00:46 Sat, after the new moon. A month with no sankranti is Adhika Bhadrapada, before Bhadrapada itself.

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 17 Aug, with the Sun in Simha, began Bhadrapada (Adhik). This Shukla paksha reads Bhadrapada (Adhik) in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 24 Mar 1955, 06:42 Thu. Since then the Sun has moved 154.2° round the stars. Vikram Samvat numbers that year 2012; Shaka Samvat numbers it 1877.
