Panchang in Sevan, Gegharkunik, Armenia Fri 27 Jun 1969

Shiva’s Pradosh puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi runs from 11:06 on Fri 27 Jun to 07:44 on Sat 28 Jun, so only Friday’s pradosha (20:34–22:21) falls within it. No text giving Pradosh Vrat’s time was found; pradosha is Tithika’s convention.

Pradosh Vrat: every date in Sevan

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 132°–144° is the 12th, Shukla Dwadashi. A day takes the tithi in force at its sunrise, 05:31 here. Ekadashi ended at 13:54 Thu, before it. Dwadashi ends at 11:06, when the lead reaches 144°. The lead passed 0° at the new moon of 15 Jun, so the Moon is waxing: Shukla paksha.

The night of Thu 26 Jun ran from sunset 20:34 Thu to sunrise 05:31, 8 h 57 m. Cut into 15 muhurtas of 35 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:31 to 20:34, splits into 8 choghadiyas of 1 h 52 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 20:34 to 05:31 Sat, splits into 8 choghadiyas of 1 h 7 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′. Vishakha spans 200°00′–213°20′; the Moon entered its pada 4 at 210°. It leaves at 06:42, for Anuradha.

Add the Sun's and the Moon's places among the stars: 71.8° + 212.6° = 284.4°. The sum, cut into 27 parts of 13°20′, gives the yoga: 280°00′–293°20′ is the 22nd, Sadhya. It ends at 19:09, then Shubha.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Dwadashi is Bava and the second Balava. Bava ended at 00:34, when the lead reached 138°; Balava runs until 11:06.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:31 to 05:31 Sat, so the hours after midnight still belong to Shukrawara.

A month normally holds one sankranti, the Sun's entry into a new rashi. From 15 Jun 03:08 Sun to 14 Jul 18:11 Mon the Sun stayed in Mithuna, entering Karka at 16 Jul 07:40 Wed, after the new moon. A month with no sankranti is Adhika Ashadha, before Ashadha itself.

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 15 Jun, with the Sun in Mithuna, began Ashadha (Adhik). This Shukla paksha reads Ashadha (Adhik) in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 18 Mar 1969, 08:51 Tue. Since then the Sun has moved 97.8° round the stars. Vikram Samvat numbers that year 2026; Shaka Samvat numbers it 1891.
