Panchang in Sevan, Gegharkunik, Armenia Thu 16 Apr 1992

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, 06:20 here. Trayodashi ended at 12:55 Wed, before it. Chaturdashi ends at 10:38, when the lead reaches 168°. The lead passed 0° at the new moon of 3 Apr, so the Moon is waxing: Shukla paksha.

The night of Wed 15 Apr ran from sunset 19:39 Wed to sunrise 06:20, 10 h 41 m. Cut into 15 muhurtas of 42 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:20 to 19:40, splits into 8 choghadiyas of 1 h 40 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 19:40 to 06:18 Fri, splits into 8 choghadiyas of 1 h 19 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 3 at 166°40′. It leaves at 14:59, for Chitra.

Add the Sun's and the Moon's places among the stars: 2.6° + 168.2° = 170.8°. The sum, cut into 27 parts of 13°20′, gives the yoga: 160°00′–173°20′ is the 13th, Vyaghata. It ends at 10:18, then Harshana.

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 ended at 23:44 Wed, when the lead reached 162°; Vanija runs until 10:38.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:20 to 06:18 Fri, so the hours after midnight still belong to Guruwara.

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: Meena gives Chaitra. The Sun enters Mesha on 13 Apr, inside the month. The next new moon, 2 May, finds it in Mesha and begins Vaishakha.

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 3 Apr, with the Sun in Meena, began Chaitra. This Shukla paksha reads Chaitra in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 3 Apr 1992, 09:01 Fri. Since then the Sun has moved 12.7° round the stars. Vikram Samvat numbers that year 2049; Shaka Samvat numbers it 1914.
