Panchang in Pāthardi, Maharashtra Tue 23 Oct 2018

Sharad Purnima’s night centres on nishitha, the midnight muhurta. Purnima runs from 22:36 on Tue 23 Oct to 22:15 on Wed 24 Oct, so only Tuesday night’s nishitha (23:48–00:38 Wed) falls within it. No text giving Sharad Purnima’s time was found; nishitha is Tithika’s convention.

Sharad Purnima: every date in Pāthardi

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 156°–168° is the 14th, Shukla Chaturdashi. A day takes the tithi in force at its sunrise, 06:25 here. Trayodashi ended at 22:23 Mon, before it. Chaturdashi ends at 22:36, when the lead reaches 168°. The lead passed 0° at the new moon of 9 Oct, so the Moon is waxing: Shukla paksha.

The night of Mon 22 Oct ran from sunset 18:01 Mon to sunrise 06:25, 12 h 24 m. Cut into 15 muhurtas of 49 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:25 to 18:00, splits into 8 choghadiyas of 1 h 26 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 06:26 Wed, splits into 8 choghadiyas of 1 h 33 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′. Uttara Bhadrapada spans 333°20′–346°40′; the Moon entered its pada 4 at 343°20′. It leaves at 08:47, for Revati.

Add the Sun's and the Moon's places among the stars: 185.5° + 345.4° = 530.9°, one full turn and 170.9°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 160°00′–173°20′ is the 13th, Vyaghata. It ends at 10:43, then Harshana.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Chaturdashi is Garaja and the second Vanija. Garaja runs until 10:34, when the lead reaches 162°; Vanija until 22:36.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:25 to 06:26 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: Kanya gives Ashwina. The Sun enters Tula on 17 Oct, inside the month. The next new moon, 7 Nov, finds it in Tula and begins Kartika.

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 9 Oct, with the Sun in Kanya, began Ashwina. This Shukla paksha reads Ashwina 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 212.7° round the stars. Vikram Samvat numbers that year 2075; Shaka Samvat numbers it 1940.
