Panchang in Sevan, Gegharkunik, Armenia Fri 30 Sep 1955

Anant Chaturdashi follows the tithi at sunrise. Chaturdashi runs from 00:58 on Fri 30 Sep to 23:54 on Fri 30 Sep, so it holds sunrise only on Fri 30 Sep, at 05:54. No text giving Anant Chaturdashi’s time was found; sunrise is Tithika’s convention.

Anant Chaturdashi: 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, 05:54 here. Trayodashi ended at 00:58, before it. Chaturdashi ends at 23:54, when the lead reaches 168°. The lead passed 0° at the new moon of 16 Sep, so the Moon is waxing: Shukla paksha.

The night of Thu 29 Sep ran from sunset 17:47 Thu to sunrise 05:54, 12 h 7 m. Cut into 15 muhurtas of 48 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:54 to 17:45, 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 night here, 17:45 to 05:55 Sat, 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 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 1 at 320°. It leaves at 02:48 Sat, for Uttara Bhadrapada.

Add the Sun's and the Moon's places among the stars: 162.9° + 321.5° = 484.4°, one full turn and 124.4°. 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 20:37, then Vriddhi.

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 runs until 12:31, when the lead reaches 162°; Vanija until 23:54.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:54 to 05:55 Sat, so the hours after midnight still belong to Shukrawara.

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, 15 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 16 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: 24 Mar 1955, 06:42 Thu. Since then the Sun has moved 183.4° round the stars. Vikram Samvat numbers that year 2012; Shaka Samvat numbers it 1877.
