Panchang in Sevan, Gegharkunik, Armenia Tue 22 Sep 2048

The first shraddha of Pitru Paksha is done in aparahna, the fourth fifth of the day. Pratipada runs from 08:46 on Tue 22 Sep to 08:15 on Wed 23 Sep, so only Tuesday’s aparahna (14:05–16:30) falls within it. No text giving Pitru Paksha begins’s time was found; aparahna is Tithika’s convention.

Pitru Paksha begins: every date in Sevan

Purnima follows the tithi at sunrise. Purnima runs from 09:48 on Mon 21 Sep to 08:46 on Tue 22 Sep, so it holds sunrise only on Tue 22 Sep, at 06:47. No text giving Purnima’s time was found; sunrise is Tithika’s convention.

Purnima: every date in Sevan

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 168°–180° is the 15th, Shukla Purnima. A day takes the tithi in force at its sunrise, 06:47 here. Chaturdashi ended at 09:48 Mon, before it. Purnima ends at 08:46, when the lead reaches 180°. The lead passed 0° at the new moon of 8 Sep, so the Moon is waxing: Shukla paksha.

The night of Mon 21 Sep ran from sunset 18:58 Mon to sunrise 06:47, 11 h 49 m. Cut into 15 muhurtas of 47 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:47 to 18:56, 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, 18:56 to 06:48 Wed, 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′. Uttara Bhadrapada spans 333°20′–346°40′; the Moon entered its pada 1 at 333°20′. It leaves at 05:17 Wed, for Revati.

Add the Sun's and the Moon's places among the stars: 155.2° + 334.2° = 489.4°, one full turn and 129.4°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 120°00′–133°20′ is the 10th, Ganda. It ends at 13:15, then Vriddhi.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Purnima is Vishti and the second Bava. Vishti ended at 21:14 Mon, when the lead reached 174°; Bava runs until 08:46.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:47 to 06:48 Wed, so the hours after midnight still belong to Mangalawara.

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: Simha gives Bhadrapada. The Sun enters Kanya on 16 Sep, inside the month. The next new moon, 7 Oct, finds it in Kanya and begins Ashwina.

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 8 Sep, with the Sun in Simha, began Bhadrapada. This Shukla paksha reads Bhadrapada in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 14 Mar 2048, 18:27 Sat. Since then the Sun has moved 185° round the stars. Vikram Samvat numbers that year 2105; Shaka Samvat numbers it 1970.
