Panchang in Ipameri, Goiás, Brazil Thu 28 Jun 2091

Shiva’s Pradosh puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi runs from 06:12 on Thu 28 Jun to 03:31 on Fri 29 Jun, so only Thursday’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 06:12, before it. Trayodashi ends at 03:31 Fri, when the lead reaches 156°. The lead passed 0° at the new moon of 16 Jun, so the Moon is waxing: Shukla paksha.

The night of Wed 27 Jun ran from sunset 17:48 Wed to sunrise 06:43, 12 h 55 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 06:44 Fri, splits into 8 choghadiyas of 1 h 37 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 1 at 213°20′. It leaves at 00:08 Fri, for Jyeshtha.

Add the Sun's and the Moon's places among the stars: 71.9° + 216.2° = 288.1°. The sum, cut into 27 parts of 13°20′, gives the yoga: 280°00′–293°20′ is the 22nd, Sadhya. It ends at 14:56, 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 16:51, when the lead reaches 150°; Taitila until 03:31 Fri.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:43 to 06:44 Fri, so the hours after midnight still belong to Guruwara.

A month normally holds one sankranti, the Sun's entry into a new rashi. From 16 Jun 23:42 Sat to 16 Jul 11:17 Mon the Sun stayed in Mithuna, entering Karka at 17 Jul 06:52 Tue, 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 16 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: 20 Mar 2091, 00:47 Tue. Since then the Sun has moved 97.2° round the stars. Vikram Samvat numbers that year 2148; Shaka Samvat numbers it 2013.
