Panchang in Ipameri, Goiás, Brazil Thu 12 Jan 1911

Lohri’s bonfire is lit on the evening before Makar Sankranti. The Sun enters Makara at 18:32 Fri, and Makar Sankranti is on Fri 13 Jan: Thu 12 Jan. No text giving Lohri’s time was found; pradosha is Tithika’s convention.

Lohri: every date in Ipameri

Shiva’s Pradosh puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi runs from 04:40 on Thu 12 Jan to 01:32 on Fri 13 Jan, so only Thursday’s pradosha (18:47–20:58) falls within it. No text giving Pradosh Vrat’s time was found; pradosha is Tithika’s convention.

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, 05:47 here. Dwadashi ended at 04:46, before it. Trayodashi ends at 01:38 Fri, when the lead reaches 156°. The lead passed 0° at the new moon of 31 Dec, so the Moon is waxing: Shukla paksha.

The night of Wed 11 Jan ran from sunset 18:53 Wed to sunrise 05:47, 10 h 54 m. Cut into 15 muhurtas of 43 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:47 to 18:54, splits into 8 choghadiyas of 1 h 38 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:54 to 05:48 Fri, splits into 8 choghadiyas of 1 h 21 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′. Rohini spans 40°00′–53°20′; the Moon entered its pada 4 at 50°. It leaves at 06:18, for Mrigashira.

Add the Sun's and the Moon's places among the stars: 268.4° + 53° = 321.4°. The sum, cut into 27 parts of 13°20′, gives the yoga: 320°00′–333°20′ is the 25th, Brahma. It ends at 23:47, then Indra.

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 15:13, when the lead reaches 150°; Taitila until 01:38 Fri.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:47 to 05:48 Fri, so the hours after midnight still belong to Guruwara.

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: Dhanu gives Pausha. The Sun enters Makara on 13 Jan, inside the month. The next new moon, 30 Jan, finds it in Makara and begins Magha.

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 31 Dec, with the Sun in Dhanu, began Pausha. This Shukla paksha reads Pausha in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 9 Apr 1910, 18:24 Sat. Since then the Sun has moved 271.9° round the stars. Vikram Samvat numbers that year 1967; Shaka Samvat numbers it 1832.
