Panchang in Sevan, Gegharkunik, Armenia Sun 17 Nov 1963

The tilak is applied in aparahna, the fourth fifth of the day. Dwitiya runs from 13:27 on Sun 17 Nov to 16:02 on Mon 18 Nov, holding as much of aparahna on both days. The Nirnayasindhu then takes the earlier: Sun 17 Nov. No text giving Bhai Dooj’s time was found; aparahna is Tithika’s convention.

Bhai Dooj: every date in Sevan

Govardhan Puja is done in pratahkala, the first fifth of the day. Pratipada runs from 10:50 on Sat 16 Nov to 13:27 on Sun 17 Nov, so only Sunday’s pratahkala (07:47–09:46) falls within it. No text giving Govardhan Puja’s time was found; pratahkala is Tithika’s convention.

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, 07:47 here. Amavasya ended at 10:50 Sat, before it. Pratipada ends at 13:27, when the lead reaches 12°. The lead passed 0° at the new moon of 16 Nov, so the Moon is waxing: Shukla paksha.

The night of Sat 16 Nov ran from sunset 17:42 Sat to sunrise 07:47, 14 h 5 m. Cut into 15 muhurtas of 56 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 07:47 to 17:41, splits into 8 choghadiyas of 1 h 14 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 17:41 to 07:48 Mon, splits into 8 choghadiyas of 1 h 45 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′. Anuradha spans 213°20′–226°40′; the Moon entered its pada 3 at 220°. It leaves at 20:58, for Jyeshtha.

Add the Sun's and the Moon's places among the stars: 210.7° + 220.2° = 430.9°, one full turn and 70.9°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 66°40′–80°00′ is the 6th, Atiganda. It ends at 00:49 Mon, then Sukarma.

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 00:08, when the lead reached 6°; Bava runs until 13:27.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 07:47 to 07:48 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: Tula gives Kartika. The Sun enters Vrishchika on 16 Nov and Dhanu on 16 Dec, both inside the month. The next new moon, 16 Dec, finds it in Dhanu and begins Pausha.

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 Nov, with the Sun in Tula, began Kartika. This Shukla paksha reads Kartika in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 25 Mar 1963, 16:09 Mon. Since then the Sun has moved 229.9° round the stars. Vikram Samvat numbers that year 2020; Shaka Samvat numbers it 1885.
