Panchang in Sevan, Gegharkunik, Armenia Mon 26 May 1980

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 132°–144° is the 12th, Shukla Dwadashi. A day takes the tithi in force at its sunrise, 05:34 here. Ekadashi ended at 19:43 Sun, before it. Dwadashi ends at 21:50, when the lead reaches 144°. The lead passed 0° at the new moon of 14 May, so the Moon is waxing: Shukla paksha.

The night of Sun 25 May ran from sunset 20:18 Sun to sunrise 05:34, 9 h 16 m. Cut into 15 muhurtas of 37 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:34 to 20:19, splits into 8 choghadiyas of 1 h 50 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 20:19 to 05:34 Tue, splits into 8 choghadiyas of 1 h 9 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′. Chitra spans 173°20′–186°40′; the Moon entered its pada 2 at 176°40′. It leaves at 23:06, for Swati.

Add the Sun's and the Moon's places among the stars: 41.4° + 177.9° = 219.3°. The sum, cut into 27 parts of 13°20′, gives the yoga: 213°20′–226°40′ is the 17th, Vyatipata. It ends at 19:16, then Variyana.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Dwadashi is Bava and the second Balava. Bava runs until 08:49, when the lead reaches 138°; Balava until 21:50.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:34 to 05:34 Tue, so the hours after midnight still belong to Somawara.

A month normally holds one sankranti, the Sun's entry into a new rashi. From 14 May 16:00 Wed to 13 Jun 00:38 Fri the Sun stayed in Vrishabha, entering Mithuna at 14 Jun 16:25 Sat, after the new moon. A month with no sankranti is Adhika Jyeshtha, before Jyeshtha 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 May, with the Sun in Vrishabha, began Jyeshtha (Adhik). This Shukla paksha reads Jyeshtha (Adhik) in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 16 Mar 1980, 22:55 Sun. Since then the Sun has moved 68.6° round the stars. Vikram Samvat numbers that year 2037; Shaka Samvat numbers it 1902.
