Panchang in Sevan, Gegharkunik, Armenia Sun 25 Jun 1995

Shiva’s Pradosh puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi runs from 21:24 on Sat 24 Jun to 23:56 on Sun 25 Jun, touching pradosha on both evenings. The Nirnayasindhu takes the evening it holds more of: Sun 25 Jun. No text giving Pradosh Vrat’s time was found; pradosha is Tithika’s convention.

Pradosh Vrat: every date in Sevan

Shiva’s worship centres on nishitha, the midnight muhurta. Chaturdashi runs from 23:56 on Sun 25 Jun to 02:27 on Tue 27 Jun, holding as much of nishitha on both nights. The Nirnayasindhu then takes the earlier: Sun 25 Jun. No text giving Masik Shivratri’s time was found; nishitha is Tithika’s convention.

Masik Shivratri: every date in Sevan

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 324°–336° is the 28th, Krishna Trayodashi. A day takes the tithi in force at its sunrise, 05:30 here. Dwadashi ended at 21:24 Sat, before it. Trayodashi ends at 23:56, when the lead reaches 336°. The lead passed 180° at the full moon of 13 Jun, so the Moon is waning: Krishna paksha.

The night of Sat 24 Jun ran from sunset 20:34 Sat to sunrise 05:30, 8 h 56 m. Cut into 15 muhurtas of 35 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:30 to 20:34, splits into 8 choghadiyas of 1 h 53 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 05:30 Mon, 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′. Krittika spans 26°40′–40°00′; the Moon entered its pada 4 at 36°40′. It leaves at 11:45, for Rohini.

Add the Sun's and the Moon's places among the stars: 69.3° + 36.9° = 106.2°. The sum, cut into 27 parts of 13°20′, gives the yoga: 93°20′–106°40′ is the 8th, Dhriti. It ends at 06:24, then Shula.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Trayodashi is Garaja and the second Vanija. Garaja runs until 10:40, when the lead reaches 330°; Vanija until 23:56.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:30 to 05:30 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: Vrishabha gives Jyeshtha. The Sun enters Mithuna on 15 Jun, inside the month. The next new moon, 28 Jun, finds it in Mithuna and begins Ashadha.

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 28 Jun, with the Sun in Mithuna, begins Ashadha. Until then this Krishna paksha reads Ashadha here, and Jyeshtha in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 31 Mar 1995, 06:08 Fri. Since then the Sun has moved 83.2° round the stars. Vikram Samvat numbers that year 2052; Shaka Samvat numbers it 1917.
