Panchang in Thazhecode, Kerala Sun 14 Sep 2031

Shiva’s Pradosh puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi runs from 20:15 on Sat 13 Sep to 22:02 on Sun 14 Sep, touching pradosha on both evenings. The Nirnayasindhu takes the evening it holds more of: Sun 14 Sep. 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 22:02 on Sun 14 Sep to 23:23 on Mon 15 Sep, so only Sunday night’s nishitha (23:58–00:45 Mon) falls within it. 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, 06:15 here. Dwadashi ended at 20:15 Sat, before it. Trayodashi ends at 22:02, when the lead reaches 336°. The lead passed 180° at the full moon of 1 Sep, so the Moon is waning: Krishna paksha.

The night of Sat 13 Sep ran from sunset 18:28 Sat to sunrise 06:15, 11 h 47 m. Cut into 15 muhurtas of 47 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:15 to 18:27, splits into 8 choghadiyas of 1 h 31 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:27 to 06:15 Mon, splits into 8 choghadiyas of 1 h 28 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′. Ashlesha spans 106°40′–120°00′; the Moon entered its pada 3 at 113°20′. It leaves at 15:25, for Magha.

Add the Sun's and the Moon's places among the stars: 146.7° + 115.4° = 262.1°. The sum, cut into 27 parts of 13°20′, gives the yoga: 253°20′–266°40′ is the 20th, Shiva. It ends at 14:38, then Siddha.

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 09:12, when the lead reaches 330°; Vanija until 22:02.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:15 to 06:15 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 18 Aug 10:02 Mon to 17 Sep 00:16 Wed the Sun stayed in Simha, entering Kanya at 17 Sep 14:49 Wed, after the new moon. A month with no sankranti is Adhika Bhadrapada, before Bhadrapada 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 17 Sep, with the Sun in Simha, begins Bhadrapada (Adhik). Until then this Krishna paksha reads Bhadrapada (Adhik) here, and Bhadrapada (Adhik) in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 23 Mar 2031, 09:19 Sun. Since then the Sun has moved 168.7° round the stars. Vikram Samvat numbers that year 2088; Shaka Samvat numbers it 1953.
