Panchang in Pāthardi, Maharashtra Mon 14 Jan 2019

Lohri’s bonfire is lit on the evening before Makar Sankranti. The Sun enters Makara at 19:51, and Makar Sankranti is on Tue 15 Jan: Mon 14 Jan. No text giving Lohri’s time was found; pradosha is Tithika’s convention.

Lohri: every date in Pāthardi

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 84°–96° is the 8th, Shukla Ashtami. A day takes the tithi in force at its sunrise, 07:05 here. Saptami ended at 23:42 Sun, before it. Ashtami ends at 00:37 Tue, when the lead reaches 96°. The lead passed 0° at the new moon of 6 Jan, so the Moon is waxing: Shukla paksha.

The night of Sun 13 Jan ran from sunset 18:10 Sun to sunrise 07:05, 12 h 55 m. Cut into 15 muhurtas of 51 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 07:05 to 18:10, 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, 18:10 to 07:05 Tue, 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′. Revati spans 346°40′–360°00′; the Moon entered its pada 4 at 356°40′. It leaves at 12:52, for Ashwini.

Add the Sun's and the Moon's places among the stars: 269.5° + 357° = 626.5°, one full turn and 266.5°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 253°20′–266°40′ is the 20th, Shiva. It ends at 07:30, then Siddha.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Ashtami is Vishti and the second Bava. Vishti runs until 12:15, when the lead reaches 90°; Bava until 00:37 Tue.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 07:05 to 07:05 Tue, so the hours after midnight still belong to Somawara.

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 14 Jan, inside the month. The next new moon, 5 Feb, 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 6 Jan, 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: 17 Mar 2018, 18:41 Sat. Since then the Sun has moved 296.7° round the stars. Vikram Samvat numbers that year 2075; Shaka Samvat numbers it 1940.
