Panchang in Sevan, Gegharkunik, Armenia Sat 24 Oct 1998

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 36°–48° is the 4th, Shukla Chaturthi. A day takes the tithi in force at its sunrise, 08:20 here. Tritiya ended at 22:32 Fri, before it. Chaturthi ends at 00:42 Sun, when the lead reaches 48°. The lead passed 0° at the new moon of 20 Oct, so the Moon is waxing: Shukla paksha.

The night of Fri 23 Oct ran from sunset 19:09 Fri to sunrise 08:20, 13 h 11 m. Cut into 15 muhurtas of 52 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 08:20 to 19:07, splits into 8 choghadiyas of 1 h 20 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 19:07 to 07:21 Sun, splits into 8 choghadiyas of 1 h 39 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′. Jyeshtha spans 226°40′–240°00′; the Moon entered its pada 1 at 226°40′. It leaves at 08:55 Sun, for Mula.

Add the Sun's and the Moon's places among the stars: 186.7° + 227.2° = 413.9°, one full turn and 53.9°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 53°20′–66°40′ is the 5th, Shobhana. It ends at 06:57 Sun, then Atiganda.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Chaturthi is Vanija and the second Vishti. Vanija runs until 11:39, when the lead reaches 42°; Vishti until 00:42 Sun.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 08:20 to 07:21 Sun, so the hours after midnight still belong to Shaniwara.

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, 19 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 20 Oct, with the Sun in Tula, began Kartika. This Shukla paksha reads Kartika in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 28 Mar 1998, 07:13 Sat. Since then the Sun has moved 203.3° round the stars. Vikram Samvat numbers that year 2055; Shaka Samvat numbers it 1920.
