Panchang in Sevan, Gegharkunik, Armenia Wed 26 Apr 1972

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, 06:05 here. Dwadashi ended at 09:49 Tue, before it. Trayodashi ends at 12:00, when the lead reaches 156°. The lead passed 0° at the new moon of 14 Apr, so the Moon is waxing: Shukla paksha.

The night of Tue 25 Apr ran from sunset 19:49 Tue to sunrise 06:05, 10 h 16 m. Cut into 15 muhurtas of 41 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:05 to 19:50, splits into 8 choghadiyas of 1 h 43 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 19:50 to 06:04 Thu, 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′. Hasta spans 160°00′–173°20′; the Moon entered its pada 2 at 163°20′. It leaves at 21:18, for Chitra.

Add the Sun's and the Moon's places among the stars: 12.5° + 165.8° = 178.3°. The sum, cut into 27 parts of 13°20′, gives the yoga: 173°20′–186°40′ is the 14th, Harshana. It ends at 21:45, then Vajra.

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 22:53 Tue, when the lead reached 150°; Taitila runs until 12:00.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:05 to 06:04 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 14 Apr 00:30 Fri to 13 May 08:08 Sat the Sun stayed in Mesha, entering Vrishabha at 14 May 08:26 Sun, after the new moon. A month with no sankranti is Adhika Vaishakha, before Vaishakha 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 14 Apr, with the Sun in Mesha, began Vaishakha (Adhik). This Shukla paksha reads Vaishakha (Adhik) in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 15 Mar 1972, 15:34 Wed. Since then the Sun has moved 41° round the stars. Vikram Samvat numbers that year 2029; Shaka Samvat numbers it 1894.
