Panchang in Sevan, Gegharkunik, Armenia Sun 15 Nov 1981

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 216°–228° is the 19th, Krishna Chaturthi. A day takes the tithi in force at its sunrise, 07:45 here. Tritiya ended at 15:23 Sat, before it. Chaturthi ends at 12:22, when the lead reaches 228°. The lead passed 180° at the full moon of 12 Nov, so the Moon is waning: Krishna paksha.

The night of Sat 14 Nov ran from sunset 17:43 Sat to sunrise 07:45, 14 h 2 m. Cut into 15 muhurtas of 56 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 07:45 to 17:42, splits into 8 choghadiyas of 1 h 14 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 17:42 to 07:47 Mon, splits into 8 choghadiyas of 1 h 45 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′. Ardra spans 66°40′–80°00′; the Moon entered its pada 3 at 73°20′. It leaves at 16:51, for Punarvasu.

Add the Sun's and the Moon's places among the stars: 209.1° + 74.5° = 283.6°. The sum, cut into 27 parts of 13°20′, gives the yoga: 280°00′–293°20′ is the 22nd, Sadhya. It ends at 22:52, then Shubha.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Chaturthi is Bava and the second Balava. Bava ended at 01:49, when the lead reached 222°; Balava runs until 12:22.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 07:45 to 07:47 Mon, so the hours after midnight still belong to Raviwara.

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: Tula gives Kartika. The Sun enters Vrishchika on 16 Nov, inside the month. The next new moon, 26 Nov, finds it in Vrishchika and begins Margashirsha.

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 26 Nov, with the Sun in Vrishchika, begins Margashirsha. Until then this Krishna paksha reads Margashirsha here, and Kartika in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 5 Apr 1981, 01:19 Sun. Since then the Sun has moved 217.7° round the stars. Vikram Samvat numbers that year 2038; Shaka Samvat numbers it 1903.
