Panchang in Sevan, Gegharkunik, Armenia Fri 6 May 1983

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 276°–288° is the 24th, Krishna Navami. A day takes the tithi in force at its sunrise, 06:53 here. Ashtami ended at 21:54 Thu, before it. Navami ends at 00:03 Sat, when the lead reaches 288°. The lead passed 180° at the full moon of 27 Apr, so the Moon is waning: Krishna paksha.

The night of Thu 5 May ran from sunset 20:58 Thu to sunrise 06:53, 9 h 55 m. Cut into 15 muhurtas of 39 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:53 to 20:59, 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 night here, 20:59 to 06:52 Sat, 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 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 3 at 300°. It leaves at 17:17, for Shatabhisha.

Add the Sun's and the Moon's places among the stars: 21.4° + 301.5° = 322.9°. The sum, cut into 27 parts of 13°20′, gives the yoga: 320°00′–333°20′ is the 25th, Brahma. It ends at 02:16 Sat, then Indra.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Navami is Taitila and the second Garaja. Taitila runs until 11:02, when the lead reaches 282°; Garaja until 00:03 Sat.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:53 to 06:52 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: Meena gives Chaitra. The Sun enters Mesha on 14 Apr, inside the month. The next new moon, 13 May, 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 13 May, with the Sun in Mesha, begins Vaishakha. Until then this Krishna paksha reads Vaishakha here, and Chaitra in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 13 Apr 1983, 12:58 Wed. Since then the Sun has moved 22.2° round the stars. Vikram Samvat numbers that year 2040; Shaka Samvat numbers it 1905.
