Panchang in Sevan, Gegharkunik, Armenia Wed 28 May 1980

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 156°–168° is the 14th, Shukla Chaturdashi. A day takes the tithi in force at its sunrise, 05:33 here. Trayodashi ended at 23:31 Tue, before it. Chaturdashi ends at 00:44 Thu, when the lead reaches 168°. The lead passed 0° at the new moon of 14 May, so the Moon is waxing: Shukla paksha.

The night of Tue 27 May ran from sunset 20:20 Tue to sunrise 05:33, 9 h 13 m. Cut into 15 muhurtas of 36 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:33 to 20:21, splits into 8 choghadiyas of 1 h 51 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 20:21 to 05:33 Thu, 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′. Vishakha spans 200°00′–213°20′; the Moon entered its pada 1 at 200°. It leaves at 03:10 Thu, for Anuradha.

Add the Sun's and the Moon's places among the stars: 43.3° + 202.2° = 245.5°. The sum, cut into 27 parts of 13°20′, gives the yoga: 240°00′–253°20′ is the 19th, Parigha. It ends at 19:44, then Shiva.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Chaturdashi is Garaja and the second Vanija. Garaja runs until 12:11, when the lead reaches 162°; Vanija until 00:44 Thu.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:33 to 05:33 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 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 70.5° round the stars. Vikram Samvat numbers that year 2037; Shaka Samvat numbers it 1902.
