Panchang in Sevan, Gegharkunik, Armenia Wed 21 Mar 2091

Ghatasthapana is done in pratahkala, the first fifth of the day. Pratipada runs from 07:47 on Tue 20 Mar to 10:22 on Wed 21 Mar, touching pratahkala on both mornings. The Nirnayasindhu takes the morning it holds more of: Wed 21 Mar. No text giving Chaitra Navratri · Ghatasthapana’s time was found; pratahkala is Tithika’s convention.

Chaitra Navratri: every date in Sevan

Vikram Samvat 2148 begins on the day Chaitra Shukla Pratipada holds sunrise: Wed 21 Mar, at 07:01. Pratipada lasts until 10:22.

Nav Samvatsar: every date in Sevan

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 0°–12° is the 1st, Shukla Pratipada. A day takes the tithi in force at its sunrise, 07:01 here. Amavasya ended at 07:47 Tue, before it. Pratipada ends at 10:22, when the lead reaches 12°. The lead passed 0° at the new moon of 20 Mar, so the Moon is waxing: Shukla paksha.

The night of Tue 20 Mar ran from sunset 19:12 Tue to sunrise 07:01, 11 h 49 m. Cut into 15 muhurtas of 47 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 07:01 to 19:13, splits into 8 choghadiyas of 1 h 31 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 19:13 to 07:00 Thu, splits into 8 choghadiyas of 1 h 28 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 08:08, for Revati.

Add the Sun's and the Moon's places among the stars: 335.6° + 346.1° = 681.7°, one full turn and 321.7°. 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 04:44 Thu, then Indra.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Pratipada is Kinstughna and the second Bava. Kinstughna ended at 21:04 Tue, when the lead reached 6°; Bava runs until 10:22.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 07:01 to 07:00 Thu, so the hours after midnight still belong to Budhawara.

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 14 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 20 Mar, with the Sun in Meena, began Chaitra. This Shukla paksha reads Chaitra in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 20 Mar 2091, 07:47 Tue. Since then the Sun has moved 0.9° round the stars. Vikram Samvat numbers that year 2148; Shaka Samvat numbers it 2013.
