Panchang in Sevan, Gegharkunik, Armenia Sat 14 Dec 1918

Gita Jayanti follows the tithi at sunrise. Ekadashi runs from 11:56 on Fri 13 Dec to 09:15 on Sat 14 Dec, so it holds sunrise only on Sat 14 Dec, at 07:12. No text giving Gita Jayanti’s time was found; sunrise is Tithika’s convention.

Gita Jayanti: every date in Sevan

Smartas test Ekadashi at sunrise: it holds sunrise on Sat 14 Dec only, at 07:12: Sat 14 Dec. Vaishnavas test arunodaya: Dashami ended at 11:56 Fri, before it (05:36–07:12).

Mokshada Ekadashi: every date in Sevan

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 120°–132° is the 11th, Shukla Ekadashi. A day takes the tithi in force at its sunrise, 07:14 here. Dashami ended at 11:58 Fri, before it. Ekadashi ends at 09:17, when the lead reaches 132°. The lead passed 0° at the new moon of 3 Dec, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise. Dwadashi began at 09:17 and ended at 06:26 Sun, between the sunrises of 07:14 and 07:15 Sun. Saturday reads Ekadashi and Sunday reads Trayodashi: Dwadashi is a kshaya tithi here.

The night of Fri 13 Dec ran from sunset 16:33 Fri to sunrise 07:14, 14 h 41 m. Cut into 15 muhurtas of 58 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 07:14 to 16:33, splits into 8 choghadiyas of 1 h 9 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 16:33 to 07:15 Sun, splits into 8 choghadiyas of 1 h 50 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′. Ashwini spans 0°00′–13°20′; the Moon entered its pada 3 at 6°40′. It leaves at 13:33, for Bharani.

Add the Sun's and the Moon's places among the stars: 238.6° + 9.5° = 248.1°. The sum, cut into 27 parts of 13°20′, gives the yoga: 240°00′–253°20′ is the 19th, Parigha. It ends at 15:14, then Shiva.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Ekadashi is Vanija and the second Vishti. Vanija ended at 22:39 Fri, when the lead reached 126°; Vishti runs until 09:17.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 07:14 to 07:15 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: Vrishchika gives Margashirsha. The Sun enters Dhanu on 15 Dec, inside the month. The next new moon, 2 Jan, finds it in Dhanu and begins Pausha.

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 Dec, with the Sun in Vrishchika, began Margashirsha. This Shukla paksha reads Margashirsha in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 11 Apr 1918, 07:33 Thu. Since then the Sun has moved 240.8° round the stars. Vikram Samvat numbers that year 1975; Shaka Samvat numbers it 1840.
