Panchang in Sevan, Gegharkunik, Armenia Mon 26 Mar 1923

Rama’s birth is celebrated at madhyahna, the middle fifth of the day. Navami runs from 07:49 on Mon 26 Mar to 07:34 on Tue 27 Mar, so only Monday’s madhyahna (10:50–13:18) falls within it.

Rama Navami: every date in Sevan

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 84°–96° is the 8th, Shukla Ashtami. A day takes the tithi in force at its sunrise, 05:55 here. Saptami ended at 07:20 Sun, before it. Ashtami ends at 07:51, when the lead reaches 96°. The lead passed 0° at the new moon of 17 Mar, so the Moon is waxing: Shukla paksha.

The night of Sun 25 Mar ran from sunset 18:16 Sun to sunrise 05:55, 11 h 39 m. Cut into 15 muhurtas of 46 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:55 to 18:17, splits into 8 choghadiyas of 1 h 32 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:17 to 05:54 Tue, splits into 8 choghadiyas of 1 h 27 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′. Ardra spans 66°40′–80°00′; the Moon entered its pada 4 at 76°40′. It leaves at 12:02, for Punarvasu.

Add the Sun's and the Moon's places among the stars: 341.7° + 76.7° = 418.4°, one full turn and 58.4°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 53°20′–66°40′ is the 5th, Shobhana. It ends at 20:10, then Atiganda.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Ashtami is Vishti and the second Bava. Vishti ended at 19:41 Sun, when the lead reached 90°; Bava runs until 07:51.

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

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 13 Apr, inside the month. The next new moon, 16 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 17 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: 17 Mar 1923, 15:51 Sat. Since then the Sun has moved 8.6° round the stars. Vikram Samvat numbers that year 1980; Shaka Samvat numbers it 1845.
