Panchang in Sevan, Gegharkunik, Armenia Tue 2 Nov 1915

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 288°–300° is the 25th, Krishna Dashami. A day takes the tithi in force at its sunrise, 06:29 here. Navami ended at 21:27 Mon, before it. Dashami ends at 21:37, when the lead reaches 300°. The lead passed 180° at the full moon of 23 Oct, so the Moon is waning: Krishna paksha.

The night of Mon 1 Nov ran from sunset 16:58 Mon to sunrise 06:29, 13 h 31 m. Cut into 15 muhurtas of 54 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:29 to 16:57, splits into 8 choghadiyas of 1 h 18 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 16:57 to 06:30 Wed, splits into 8 choghadiyas of 1 h 41 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′. Magha spans 120°00′–133°20′; the Moon entered its pada 3 at 126°40′. It leaves at 15:40, for Purva Phalguni.

Add the Sun's and the Moon's places among the stars: 195.9° + 128.4° = 324.3°. The sum, cut into 27 parts of 13°20′, gives the yoga: 320°00′–333°20′ is the 25th, Brahma. It ends at 21:56, then Indra.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Dashami is Vanija and the second Vishti. Vanija runs until 09:39, when the lead reaches 294°; Vishti until 21:37.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:29 to 06:30 Wed, so the hours after midnight still belong to Mangalawara.

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: Kanya gives Ashwina. The Sun enters Tula on 17 Oct, inside the month. The next new moon, 7 Nov, finds it in Tula and begins Kartika.

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 7 Nov, with the Sun in Tula, begins Kartika. Until then this Krishna paksha reads Kartika here, and Ashwina in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 15 Mar 1915, 22:41 Mon. Since then the Sun has moved 224.4° round the stars. Vikram Samvat numbers that year 1972; Shaka Samvat numbers it 1837.
