Panchang in Sevan, Gegharkunik, Armenia Sun 28 Nov 1909

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 180°–192° is the 16th, Krishna Pratipada. A day takes the tithi in force at its sunrise, 07:00 here. Purnima ended at 11:51 Sat, before it. Pratipada ends at 09:10, when the lead reaches 192°. The lead passed 180° at the full moon of 27 Nov, so the Moon is waning: Krishna paksha.

A day takes the tithi in force at its sunrise. Dwitiya began at 09:10 and ended at 06:57 Mon, between the sunrises of 07:00 and 07:01 Mon. Sunday reads Pratipada and Monday reads Tritiya: Dwitiya is a kshaya tithi here.

The night of Sat 27 Nov ran from sunset 16:35 Sat to sunrise 07:00, 14 h 25 m. Cut into 15 muhurtas of 57 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 07:00 to 16:35, splits into 8 choghadiyas of 1 h 11 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 16:35 to 07:01 Mon, splits into 8 choghadiyas of 1 h 48 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′. Mrigashira spans 53°20′–66°40′; the Moon entered its pada 1 at 53°20′. It leaves at 05:10 Mon, for Ardra.

Add the Sun's and the Moon's places among the stars: 222.7° + 53.5° = 276.2°. The sum, cut into 27 parts of 13°20′, gives the yoga: 266°40′–280°00′ is the 21st, Siddha. It ends at 12:56, then Sadhya.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Pratipada is Balava and the second Kaulava. Balava ended at 22:28 Sat, when the lead reached 186°; Kaulava runs until 09:10.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 07:00 to 07:01 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 15 Nov, inside the month. The next new moon, 12 Dec, 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 12 Dec, 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: 21 Mar 1909, 23:11 Sun. Since then the Sun has moved 244.7° round the stars. Vikram Samvat numbers that year 1966; Shaka Samvat numbers it 1831.
