Panchang in Pāthardi, Maharashtra Thu 18 Apr 1901

Amavasya follows the tithi at sunrise. Amavasya begins at 06:46 on Thu 18 Apr, after that sunrise, and ends at 02:58 on Fri 19 Apr, before the next: it holds no sunrise. A tithi that holds no sunrise is kept on the day it is current: Thu 18 Apr. No text giving Amavasya’s time was found; sunrise is Tithika’s convention.

Amavasya: every date in Pāthardi

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 336°–348° is the 29th, Krishna Chaturdashi. A day takes the tithi in force at its sunrise, 06:01 here. Trayodashi ended at 10:25 Wed, before it. Chaturdashi ends at 06:46, when the lead reaches 348°. The lead passed 180° at the full moon of 4 Apr, so the Moon is waning: Krishna paksha.

A day takes the tithi in force at its sunrise. Amavasya began at 06:46 and ended at 02:58 Fri, between the sunrises of 06:01 and 06:00 Fri. Thursday reads Chaturdashi and Friday reads Pratipada: Amavasya is a kshaya tithi here.

The night of Wed 17 Apr ran from sunset 18:38 Wed to sunrise 06:01, 11 h 23 m. Cut into 15 muhurtas of 45 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:01 to 18:38, splits into 8 choghadiyas of 1 h 34 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:38 to 06:00 Fri, splits into 8 choghadiyas of 1 h 25 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 2 at 350°. It leaves at 18:03, for Ashwini.

Add the Sun's and the Moon's places among the stars: 4.8° + 352.4° = 357.2°. The sum, cut into 27 parts of 13°20′, gives the yoga: 346°40′–360°00′ is the 27th, Vaidhriti. It ends at 10:12, then Vishkambha.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Chaturdashi is Vishti and the second Shakuni. Vishti ended at 20:37 Wed, when the lead reached 342°; Shakuni runs until 06:46.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:01 to 06:00 Fri, so the hours after midnight still belong to Guruwara.

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: Meena gives Chaitra. The Sun enters Mesha on 13 Apr, inside the month. The next new moon, 19 Apr, finds it in Mesha and begins Vaishakha.

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 19 Apr, with the Sun in Mesha, begins Vaishakha. Until then this Krishna paksha reads Vaishakha here, and Chaitra in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 20 Mar 1901, 18:14 Wed. Since then the Sun has moved 28° round the stars. Vikram Samvat numbers that year 1958; Shaka Samvat numbers it 1823.
