Panchang in Ipameri, Goiás, Brazil Tue 12 Jan 1915

Lohri’s bonfire is lit on the evening before Makar Sankranti. The Sun enters Makara at 19:21 Wed, and Makar Sankranti is on Wed 13 Jan: Tue 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 19:10 on Tue 12 Jan to 16:27 on Wed 13 Jan, so it touches only Tuesday’s pradosha (18:54–21:04). 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: 312°–324° is the 27th, Krishna Dwadashi. A day takes the tithi in force at its sunrise, 05:47 here. Ekadashi ended at 21:56 Mon, before it. Dwadashi ends at 19:10, when the lead reaches 324°. The lead passed 180° at the full moon of 1 Jan, so the Moon is waning: Krishna paksha.

The night of Mon 11 Jan ran from sunset 18:53 Mon 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 Wed, 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′. Anuradha spans 213°20′–226°40′; the Moon entered its pada 4 at 223°20′. It leaves at 08:48, for Jyeshtha.

Add the Sun's and the Moon's places among the stars: 268.4° + 224.8° = 493.2°, one full turn and 133.2°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 120°00′–133°20′ is the 10th, Ganda. It ends at 05:55, then Vriddhi.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Dwadashi is Kaulava and the second Taitila. Kaulava runs until 08:33, when the lead reaches 318°; Taitila until 19:10.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:47 to 05:48 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: Dhanu gives Pausha. The Sun enters Makara on 13 Jan, inside the month. The next new moon, 15 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 15 Jan, with the Sun in Makara, begins Magha. Until then this Krishna paksha reads Magha here, and Pausha in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 26 Mar 1914, 15:08 Thu. Since then the Sun has moved 285.8° round the stars. Vikram Samvat numbers that year 1971; Shaka Samvat numbers it 1836.
