Panchang in Cuenca, Azuay, Ecuador Sun 13 Aug 2023

Shiva’s Pradosh puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi runs from 21:50 on Sat 12 Aug to 23:55 on Sun 13 Aug, so only Sunday’s pradosha (18:21–20:45) falls within it. No text giving Pradosh Vrat’s time was found; pradosha is Tithika’s convention.

Shiva’s worship centres on nishitha, the midnight muhurta. Chaturdashi runs from 23:55 on Sun 13 Aug to 02:13 on Tue 15 Aug, holding as much of nishitha on both nights. The Nirnayasindhu then takes the earlier: Sun 13 Aug. No text giving Masik Shivratri’s time was found; nishitha is Tithika’s convention.

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, 06:20 here. Dwadashi ended at 21:50 Sat, before it. Trayodashi ends at 23:55, when the lead reaches 336°. The lead passed 180° at the full moon of 1 Aug, so the Moon is waning: Krishna paksha.

The night of Sat 12 Aug ran from sunset 18:21 Sat to sunrise 06:20, 11 h 59 m. Cut into 15 muhurtas of 47 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:20 to 18:21, splits into 8 choghadiyas of 1 h 30 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:21 to 06:20 Mon, splits into 8 choghadiyas of 1 h 29 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 2 at 83°20′. It leaves at 00:36 Mon, for Pushya.

Add the Sun's and the Moon's places among the stars: 116.3° + 84.2° = 200.5°. The sum, cut into 27 parts of 13°20′, gives the yoga: 200°00′–213°20′ is the 16th, Siddhi. It ends at 06:09 Mon, then Vyatipata.

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 10:51, when the lead reaches 330°; Vanija until 23:55.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:20 to 06:20 Mon, so the hours after midnight still belong to Raviwara.

A month normally holds one sankranti, the Sun's entry into a new rashi. From 17 Jul 13:31 Mon to 16 Aug 04:38 Wed the Sun stayed in Karka, entering Simha at 17 Aug 03:02 Thu, 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: 21 Mar 2023, 12:23 Tue. Since then the Sun has moved 139.7° round the stars. Vikram Samvat numbers that year 2080; Shaka Samvat numbers it 1945.
