Panchang in Sevan, Gegharkunik, Armenia Wed 29 Nov 2017

Gita Jayanti follows the tithi at sunrise. Ekadashi begins at 09:21 on Wed 29 Nov, after that sunrise, and ends at 07:56 on Thu 30 Nov, before the next: it holds no sunrise. A tithi that holds no sunrise is kept on the day it is current: Wed 29 Nov. No text giving Gita Jayanti’s time was found; sunrise is Tithika’s convention.

Gita Jayanti: every date in Sevan

Mokshada Ekadashi: every date in Sevan

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 108°–120° is the 10th, Shukla Dashami. A day takes the tithi in force at its sunrise, 08:01 here. Navami ended at 09:54 Tue, before it. Dashami ends at 09:21, when the lead reaches 120°. The lead passed 0° at the new moon of 18 Nov, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise. Ekadashi began at 09:21 and ended at 07:56 Thu, between the sunrises of 08:01 and 08:02 Thu. Wednesday reads Dashami and Thursday reads Dwadashi: Ekadashi is a kshaya tithi here.

The night of Tue 28 Nov ran from sunset 17:34 Tue to sunrise 08:01, 14 h 27 m. Cut into 15 muhurtas of 57 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 08:01 to 17:34, 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, 17:34 to 08:02 Thu, 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′. Uttara Bhadrapada spans 333°20′–346°40′; the Moon entered its pada 3 at 340°. It leaves at 15:42, for Revati.

Add the Sun's and the Moon's places among the stars: 223° + 342.3° = 565.3°, one full turn and 205.3°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 200°00′–213°20′ is the 16th, Siddhi. It ends at 21:07, then Vyatipata.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Dashami is Taitila and the second Garaja. Taitila ended at 21:44 Tue, when the lead reached 114°; Garaja runs until 09:21.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 08:01 to 08:02 Thu, so the hours after midnight still belong to Budhawara.

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 16 Dec, inside the month. The next new moon, 18 Dec, 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 18 Nov, 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: 28 Mar 2017, 06:57 Tue. Since then the Sun has moved 239.5° round the stars. Vikram Samvat numbers that year 2074; Shaka Samvat numbers it 1939.
