Panchang in Sevan, Gegharkunik, Armenia Sun 26 Mar 1933

Ghatasthapana is done in pratahkala, the first fifth of the day. Pratipada runs from 06:20 on Sun 26 Mar to 07:17 on Mon 27 Mar, touching pratahkala on both mornings. The Nirnayasindhu takes the morning it holds more of: Sun 26 Mar. No text giving Chaitra Navratri · Ghatasthapana’s time was found; pratahkala is Tithika’s convention.

Chaitra Navratri: every date in Sevan

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, 05:54 here. Chaturdashi ended at 05:49 Sat, before it. Amavasya ends at 06:20, when the lead reaches 360°. The lead passed 180° at the full moon of 12 Mar, so the Moon is waning: Krishna paksha.

A day takes the tithi in force at its sunrise. Amavasya began at 05:49 Sat, before sunrise at 05:56 Sat, and ends at 06:20, after the next sunrise at 05:54. Both days read Amavasya: it is a vriddhi tithi here.

The night of Sat 25 Mar ran from sunset 18:16 Sat to sunrise 05:54, 11 h 38 m. Cut into 15 muhurtas of 46 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:54 to 18:17, 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 night here, 18:17 to 05:53 Mon, 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 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 3 at 340°. It leaves at 15:02, for Revati.

Add the Sun's and the Moon's places among the stars: 342.1° + 341.9° = 684°, one full turn and 324°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 320°00′–333°20′ is the 25th, Brahma. It ends at 22:30, then Indra.

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 ended at 18:01 Sat, when the lead reached 354°; Nagava runs until 06:20.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:54 to 05:53 Mon, so the hours after midnight still belong to Raviwara.

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, 26 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 26 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: 6 Apr 1932, 04:20 Wed. Since then the Sun has moved 349° round the stars. Vikram Samvat numbers that year 1989; Shaka Samvat numbers it 1854.
