Panchang in Sevan, Gegharkunik, Armenia Fri 18 Aug 2090

Krishna’s birth is celebrated at nishitha, the midnight muhurta. Ashtami runs from 02:37 on Fri 18 Aug to 03:25 on Sat 19 Aug, so only Friday night’s nishitha (00:43 Sat–01:24 Sat) falls within it. Every reading takes that day.

Janmashtami: every date in Sevan

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 264°–276° is the 23rd, Krishna Ashtami. A day takes the tithi in force at its sunrise, 06:14 here. Saptami ended at 02:37, before it. Ashtami ends at 03:25 Sat, when the lead reaches 276°. The lead passed 180° at the full moon of 10 Aug, so the Moon is waning: Krishna paksha.

The night of Thu 17 Aug ran from sunset 19:54 Thu to sunrise 06:14, 10 h 20 m. Cut into 15 muhurtas of 41 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:14 to 19:53, splits into 8 choghadiyas of 1 h 42 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 19:53 to 06:15 Sat, splits into 8 choghadiyas of 1 h 17 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′. Bharani spans 13°20′–26°40′; the Moon entered its pada 4 at 23°20′. It leaves at 06:57, for Krittika.

Add the Sun's and the Moon's places among the stars: 120.6° + 26.3° = 146.9°. The sum, cut into 27 parts of 13°20′, gives the yoga: 146°40′–160°00′ is the 12th, Dhruva. It ends at 05:28 Sat, then Vyaghata.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Ashtami is Balava and the second Kaulava. Balava runs until 15:07, when the lead reaches 270°; Kaulava until 03:25 Sat.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:14 to 06:15 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: Karka gives Shravana. The Sun enters Simha on 17 Aug, inside the month. The next new moon, 25 Aug, finds it in Simha and begins Bhadrapada.

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 25 Aug, with the Sun in Simha, begins Bhadrapada. Until then this Krishna paksha reads Bhadrapada here, and Shravana in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 31 Mar 2090, 07:49 Fri. Since then the Sun has moved 134.8° round the stars. Vikram Samvat numbers that year 2147; Shaka Samvat numbers it 2012.
