Panchang in Sevan, Gegharkunik, Armenia Tue 4 Sep 1990

Anant Chaturdashi follows the tithi at sunrise. Chaturdashi runs from 08:26 on Mon 3 Sep to 07:54 on Tue 4 Sep, so it holds sunrise only on Tue 4 Sep, at 07:29. No text giving Anant Chaturdashi’s time was found; sunrise is Tithika’s convention.

Anant Chaturdashi: every date in Sevan

Purnima follows the tithi at sunrise. Purnima begins at 07:54 on Tue 4 Sep, after that sunrise, and ends at 06:45 on Wed 5 Sep, before the next: it holds no sunrise. A tithi that holds no sunrise is kept on the day it is current: Tue 4 Sep. 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: 156°–168° is the 14th, Shukla Chaturdashi. A day takes the tithi in force at its sunrise, 07:29 here. Trayodashi ended at 08:26 Mon, before it. Chaturdashi ends at 07:54, when the lead reaches 168°. The lead passed 0° at the new moon of 20 Aug, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise. Purnima began at 07:54 and ended at 06:45 Wed, between the sunrises of 07:29 and 07:30 Wed. Tuesday reads Chaturdashi and Wednesday reads Pratipada: Purnima is a kshaya tithi here.

The night of Mon 3 Sep ran from sunset 20:29 Mon to sunrise 07:29, 11 h 0 m. Cut into 15 muhurtas of 44 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 07:29 to 20:28, splits into 8 choghadiyas of 1 h 37 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 20:28 to 07:30 Wed, splits into 8 choghadiyas of 1 h 22 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′. Dhanishtha spans 293°20′–306°40′; the Moon entered its pada 4 at 303°20′. It leaves at 09:48, for Shatabhisha.

Add the Sun's and the Moon's places among the stars: 137.6° + 305.4° = 443°, one full turn and 83°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 80°00′–93°20′ is the 7th, Sukarma. It ends at 00:39 Wed, then Dhriti.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Chaturdashi is Garaja and the second Vanija. Garaja ended at 20:15 Mon, when the lead reached 162°; Vanija runs until 07:54.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 07:29 to 07:30 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 17 Sep, inside the month. The next new moon, 19 Sep, 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 20 Aug, 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: 27 Mar 1990, 00:48 Tue. Since then the Sun has moved 155.4° round the stars. Vikram Samvat numbers that year 2047; Shaka Samvat numbers it 1912.
