Panchang in Sevan, Gegharkunik, Armenia Sat 14 Aug 2088

Shiva’s Pradosh puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi runs from 05:27 on Sat 14 Aug to 02:16 on Sun 15 Aug, so only Saturday’s pradosha (19:57–22:00) falls within it. 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 02:16 on Sun 15 Aug to 23:10 on Sun 15 Aug, between the two nights’ nishitha, touching neither. The Nirnayasindhu then takes the earlier day: Sat 14 Aug. 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, 06:10 here. Dwadashi ended at 05:27, before it. Trayodashi ends at 02:16 Sun, when the lead reaches 336°. The lead passed 180° at the full moon of 2 Aug, so the Moon is waning: Krishna paksha.

Sunrise here, 05:50, came before Dwadashi ended at 06:57: this day reads Dwadashi. Trayodashi ends at 03:46 Sun, before the next sunrise, so no day here reads Trayodashi: it is kshaya.

The night of Fri 13 Aug ran from sunset 19:59 Fri to sunrise 06:10, 10 h 11 m. Cut into 15 muhurtas of 40 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:10 to 19:57, splits into 8 choghadiyas of 1 h 43 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 19:57 to 06:11 Sun, splits into 8 choghadiyas of 1 h 16 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′. Punarvasu spans 80°00′–93°20′; the Moon entered its pada 1 at 80°. It leaves at 01:10 Sun, for Pushya.

Add the Sun's and the Moon's places among the stars: 117.2° + 81.6° = 198.8°. The sum, cut into 27 parts of 13°20′, gives the yoga: 186°40′–200°00′ is the 15th, Vajra. It ends at 07:57, then Siddhi.

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 15:52, when the lead reaches 330°; Vanija until 02:16 Sun.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:10 to 06:11 Sun, so the hours after midnight still belong to Shaniwara.

A month normally holds one sankranti, the Sun's entry into a new rashi. From 18 Jul 12:40 Sun to 16 Aug 20:16 Mon the Sun stayed in Karka, entering Simha at 17 Aug 03:57 Tue, after the new moon. A month with no sankranti is Adhika Shravana, before Shravana 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 16 Aug, with the Sun in Karka, begins Shravana (Adhik). Until then this Krishna paksha reads Shravana (Adhik) here, and Shravana (Adhik) in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 23 Mar 2088, 04:01 Tue. Since then the Sun has moved 139° round the stars. Vikram Samvat numbers that year 2145; Shaka Samvat numbers it 2010.
