Panchang in Ipameri, Goiás, Brazil Tue 25 Apr 2006

Shiva’s Pradosh puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi runs from 01:16 on Tue 25 Apr to 22:19 on Tue 25 Apr, so only Tuesday’s pradosha (17:56–20:26) falls within it. No text giving Pradosh Vrat’s time was found; pradosha is Tithika’s convention.

Pradosh Vrat: every date in Ipameri

Shiva’s worship centres on nishitha, the midnight muhurta. Chaturdashi runs from 22:19 on Tue 25 Apr to 19:26 on Wed 26 Apr, so only Tuesday night’s nishitha (23:45–00:35 Wed) 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, 06:24 here. Dwadashi ended at 01:16, before it. Trayodashi ends at 22:19, when the lead reaches 336°. The lead passed 180° at the full moon of 13 Apr, so the Moon is waning: Krishna paksha.

The night of Mon 24 Apr ran from sunset 17:57 Mon to sunrise 06:24, 12 h 27 m. Cut into 15 muhurtas of 49 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:24 to 17:56, splits into 8 choghadiyas of 1 h 26 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 17:56 to 06:24 Wed, splits into 8 choghadiyas of 1 h 33 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 Bhadrapada spans 333°20′–346°40′; the Moon entered its pada 2 at 336°40′. It leaves at 20:34, for Revati.

Add the Sun's and the Moon's places among the stars: 11.1° + 338° = 349.1°. The sum, cut into 27 parts of 13°20′, gives the yoga: 346°40′–360°00′ is the 27th, Vaidhriti. It ends at 23:07, then Vishkambha.

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 11:48, when the lead reaches 330°; Vanija until 22:19.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:24 to 06:24 Wed, so the hours after midnight still belong to Mangalawara.

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: Meena gives Chaitra. The Sun enters Mesha on 13 Apr, inside the month. The next new moon, 27 Apr, finds it in Mesha and begins Vaishakha.

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 27 Apr, with the Sun in Mesha, begins Vaishakha. Until then this Krishna paksha reads Vaishakha here, and Chaitra in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 29 Mar 2006, 07:15 Wed. Since then the Sun has moved 26.5° round the stars. Vikram Samvat numbers that year 2063; Shaka Samvat numbers it 1928.
