Panchang in Devadurga, Karnataka Sat 17 Mar 2018

Amavasya follows the tithi at sunrise. Amavasya runs from 18:18 on Fri 16 Mar to 18:41 on Sat 17 Mar, so it holds sunrise only on Sat 17 Mar, at 06:29. No text giving Amavasya’s time was found; sunrise is Tithika’s convention.

Amavasya: every date in Devadurga

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 348°–360° is the 30th, Krishna Amavasya. A day takes the tithi in force at its sunrise, 06:29 here. Chaturdashi ended at 18:18 Fri, before it. Amavasya ends at 18:41, when the lead reaches 360°. The lead passed 180° at the full moon of 2 Mar, so the Moon is waning: Krishna paksha.

The night of Fri 16 Mar ran from sunset 18:32 Fri to sunrise 06:29, 11 h 57 m. Cut into 15 muhurtas of 47 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:29 to 18:32, splits into 8 choghadiyas of 1 h 30 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:32 to 06:28 Sun, splits into 8 choghadiyas of 1 h 29 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′. Purva Bhadrapada spans 320°00′–333°20′; the Moon entered its pada 2 at 323°20′. It leaves at 19:43, for Uttara Bhadrapada.

Add the Sun's and the Moon's places among the stars: 332.3° + 326.2° = 658.5°, one full turn and 298.5°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 293°20′–306°40′ is the 23rd, Shubha. It ends at 20:35, then Shukla.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Amavasya is Chatushpada and the second Nagava. Chatushpada runs until 06:34, when the lead reaches 354°; Nagava until 18:41.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:29 to 06:28 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: Kumbha gives Phalguna. The Sun enters Meena on 14 Mar, inside the month. The next new moon, 17 Mar, finds it in Meena and begins Chaitra.

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 17 Mar, with the Sun in Meena, begins Chaitra. Until then this Krishna paksha reads Chaitra here, and Phalguna in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 28 Mar 2017, 08:27 Tue. Since then the Sun has moved 348.8° round the stars. Vikram Samvat numbers that year 2074; Shaka Samvat numbers it 1939.
