Panchang in Pāthardi, Maharashtra Sat 19 Oct 1918

Sharad Purnima’s night centres on nishitha, the midnight muhurta. Purnima runs from 06:58 on Sat 19 Oct to 03:04 on Sun 20 Oct, so only Saturday night’s nishitha (23:49–00:39 Sun) falls within it. No text giving Sharad Purnima’s time was found; nishitha is Tithika’s convention.

Sharad Purnima: every date in Pāthardi

Purnima follows the tithi at sunrise. Purnima begins at 06:58 on Sat 19 Oct, after that sunrise, and ends at 03:04 on Sun 20 Oct, before the next: it holds no sunrise. A tithi that holds no sunrise is kept on the day it is current: Sat 19 Oct. No text giving Purnima’s time was found; sunrise is Tithika’s convention.

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, 06:24 here. Trayodashi ended at 10:46 Fri, before it. Chaturdashi ends at 06:58, when the lead reaches 168°. The lead passed 0° at the new moon of 5 Oct, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise. Purnima began at 06:58 and ended at 03:04 Sun, between the sunrises of 06:24 and 06:24 Sun. Saturday reads Chaturdashi and Sunday reads Pratipada: Purnima is a kshaya tithi here.

The night of Fri 18 Oct ran from sunset 18:04 Fri to sunrise 06:24, 12 h 20 m. Cut into 15 muhurtas of 49 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:24 to 18:04, splits into 8 choghadiyas of 1 h 27 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:04 to 06:24 Sun, splits into 8 choghadiyas of 1 h 32 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 1 at 346°40′. It leaves at 22:25, for Ashwini.

Add the Sun's and the Moon's places among the stars: 182.1° + 349.8° = 531.9°, one full turn and 171.9°. 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 08:33, 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 ended at 20:53 Fri, when the lead reached 162°; Vanija runs until 06:58.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:24 to 06:24 Sun, so the hours after midnight still belong to Shaniwara.

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, 4 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 5 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: 11 Apr 1918, 10:03 Thu. Since then the Sun has moved 184.3° round the stars. Vikram Samvat numbers that year 1975; Shaka Samvat numbers it 1840.
