Panchang in Ipameri, Goiás, Brazil Fri 27 Jun 1969

Shiva’s Pradosh puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi runs from 04:06 on Fri 27 Jun to 00:44 on Sat 28 Jun, so only Friday’s pradosha (17:48–20:23) falls within it. No text giving Pradosh Vrat’s time was found; pradosha is Tithika’s convention.

Pradosh Vrat: every date in Ipameri

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, 06:43 here. Dwadashi ended at 04:06, before it. Trayodashi ends at 00:44 Sat, when the lead reaches 156°. The lead passed 0° at the new moon of 14 Jun, so the Moon is waxing: Shukla paksha.

The night of Thu 26 Jun ran from sunset 17:47 Thu to sunrise 06:43, 12 h 56 m. Cut into 15 muhurtas of 51 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:43 to 17:48, splits into 8 choghadiyas of 1 h 23 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 17:48 to 06:43 Sat, splits into 8 choghadiyas of 1 h 36 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′. Anuradha spans 213°20′–226°40′; the Moon entered its pada 2 at 216°40′. It leaves at 21:16, for Jyeshtha.

Add the Sun's and the Moon's places among the stars: 72.1° + 217.6° = 289.7°. The sum, cut into 27 parts of 13°20′, gives the yoga: 280°00′–293°20′ is the 22nd, Sadhya. It ends at 12:09, then Shubha.

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 14:29, when the lead reaches 150°; Taitila until 00:44 Sat.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:43 to 06:43 Sat, so the hours after midnight still belong to Shukrawara.

A month normally holds one sankranti, the Sun's entry into a new rashi. From 14 Jun 20:08 Sat to 14 Jul 11:11 Mon the Sun stayed in Mithuna, entering Karka at 16 Jul 00:40 Wed, after the new moon. A month with no sankranti is Adhika Ashadha, before Ashadha 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 14 Jun, with the Sun in Mithuna, began Ashadha (Adhik). This Shukla paksha reads Ashadha (Adhik) in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 18 Mar 1969, 01:51 Tue. Since then the Sun has moved 98.1° round the stars. Vikram Samvat numbers that year 2026; Shaka Samvat numbers it 1891.
