Panchang in Myjava, Trenčín Region, Slovakia Sun 24 Jul 2011

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, 05:12 here. Ashtami ended at 20:09 Sat, before it. Navami ends at 22:08, when the lead reaches 288°. The lead passed 180° at the full moon of 15 Jul, so the Moon is waning: Krishna paksha.

The night of Sat 23 Jul ran from sunset 20:40 Sat to sunrise 05:12, 8 h 32 m. Cut into 15 muhurtas of 34 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:12 to 20:39, splits into 8 choghadiyas of 1 h 55 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 20:39 to 05:13 Mon, splits into 8 choghadiyas of 1 h 4 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 2 at 16°40′. It leaves at 00:19 Mon, for Krittika.

Add the Sun's and the Moon's places among the stars: 96.9° + 17° = 113.9°. The sum, cut into 27 parts of 13°20′, gives the yoga: 106°40′–120°00′ is the 9th, Shula. It ends at 16:23, then Ganda.

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 09:12, when the lead reaches 282°; Garaja until 22:08.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:12 to 05:13 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: Mithuna gives Ashadha. The Sun enters Karka on 16 Jul, inside the month. The next new moon, 30 Jul, finds it in Karka and begins Shravana.

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 30 Jul, with the Sun in Karka, begins Shravana. Until then this Krishna paksha reads Shravana here, and Ashadha in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 3 Apr 2011, 16:32 Sun. Since then the Sun has moved 107.4° round the stars. Vikram Samvat numbers that year 2068; Shaka Samvat numbers it 1933.
