Panchang in Thazhecode, Kerala Sat 30 Aug 2031

Shiva’s Pradosh puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi runs from 00:48 on Sat 30 Aug to 21:26 on Sat 30 Aug, so only Saturday’s pradosha (18:37–20:57) falls within it. No text giving Pradosh Vrat’s time was found; pradosha is Tithika’s convention.

Pradosh Vrat: every date in Thazhecode

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 144°–156° is the 13th, Shukla Trayodashi. A day takes the tithi in force at its sunrise, 06:16 here. Dwadashi ended at 00:48, before it. Trayodashi ends at 21:26, when the lead reaches 156°. The lead passed 0° at the new moon of 18 Aug, so the Moon is waxing: Shukla paksha.

The night of Fri 29 Aug ran from sunset 18:37 Fri to sunrise 06:16, 11 h 39 m. Cut into 15 muhurtas of 46 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:16 to 18:37, splits into 8 choghadiyas of 1 h 32 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:37 to 06:16 Sun, splits into 8 choghadiyas of 1 h 27 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′. Uttara Ashadha spans 266°40′–280°00′; the Moon entered its pada 4 at 276°40′. It leaves at 07:18, for Shravana.

Add the Sun's and the Moon's places among the stars: 132.2° + 279.4° = 411.6°, one full turn and 51.6°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 40°00′–53°20′ is the 4th, Saubhagya. It ends at 08:58, then Shobhana.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Trayodashi is Kaulava and the second Taitila. Kaulava runs until 11:08, when the lead reaches 150°; Taitila until 21:26.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:16 to 06:16 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 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 18 Aug, with the Sun in Simha, began Bhadrapada (Adhik). This Shukla paksha reads Bhadrapada (Adhik) in both counts.

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 154.2° round the stars. Vikram Samvat numbers that year 2088; Shaka Samvat numbers it 1953.
