Panchang in Pāthardi, Maharashtra Mon 28 Dec 2015

The Sankashti fast is broken at moonrise. Chaturthi runs from 14:42 on Mon 28 Dec to 15:28 on Tue 29 Dec, so it holds moonrise only on Mon 28 Dec, at 20:52. No text giving Sankashti Chaturthi’s time was found; moonrise is Tithika’s convention.

Sankashti Chaturthi: every date in Pāthardi

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 204°–216° is the 18th, Krishna Tritiya. A day takes the tithi in force at its sunrise, 07:00 here. Dwitiya ended at 14:42 Sun, before it. Tritiya ends at 14:42, when the lead reaches 216°. The lead passed 180° at the full moon of 25 Dec, so the Moon is waning: Krishna paksha.

The night of Sun 27 Dec ran from sunset 17:59 Sun to sunrise 07:00, 13 h 1 m. Cut into 15 muhurtas of 52 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 07:00 to 18:00, splits into 8 choghadiyas of 1 h 22 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:00 to 07:01 Tue, 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′. Pushya spans 93°20′–106°40′; the Moon entered its pada 4 at 103°20′. It leaves at 11:49, for Ashlesha.

Add the Sun's and the Moon's places among the stars: 251.9° + 104.1° = 356°. The sum, cut into 27 parts of 13°20′, gives the yoga: 346°40′–360°00′ is the 27th, Vaidhriti. It ends at 13:57, then Vishkambha.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Tritiya is Vanija and the second Vishti. Vanija ended at 02:36, when the lead reached 210°; Vishti runs until 14:42.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 07:00 to 07:01 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: Vrishchika gives Margashirsha. The Sun enters Dhanu on 16 Dec, inside the month. The next new moon, 10 Jan, finds it in Dhanu and begins Pausha.

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 10 Jan, with the Sun in Dhanu, begins Pausha. Until then this Krishna paksha reads Pausha here, and Margashirsha in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 20 Mar 2015, 15:06 Fri. Since then the Sun has moved 276.5° round the stars. Vikram Samvat numbers that year 2072; Shaka Samvat numbers it 1937.
