Panchang in Codcod, Western Visayas, Philippines Sun 11 Sep 2016

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 96°–108° is the 9th, Shukla Navami. A day takes the tithi in force at its sunrise, 05:37 here. Ashtami ended at 08:41 Sat, before it. Navami ends at 09:59, when the lead reaches 108°. The lead passed 0° at the new moon of 1 Sep, so the Moon is waxing: Shukla paksha.

The night of Sat 10 Sep ran from sunset 17:50 Sat to sunrise 05:37, 11 h 47 m. Cut into 15 muhurtas of 47 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:37 to 17:50, splits into 8 choghadiyas of 1 h 31 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 17:50 to 05:37 Mon, splits into 8 choghadiyas of 1 h 28 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′. Mula spans 240°00′–253°20′; the Moon entered its pada 4 at 250°. It leaves at 11:14, for Purva Ashadha.

Add the Sun's and the Moon's places among the stars: 144.5° + 250.4° = 394.9°, one full turn and 34.9°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 26°40′–40°00′ is the 3rd, Ayushmana. It ends at 14:40, then Saubhagya.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Navami is Balava and the second Kaulava. Balava ended at 21:25 Sat, when the lead reached 102°; Kaulava runs until 09:59.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:37 to 05:37 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: Simha gives Bhadrapada. The Sun enters Kanya on 16 Sep, inside the month. The next new moon, 1 Oct, finds it in Kanya and begins Ashwina.

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 1 Sep, with the Sun in Simha, began Bhadrapada. This Shukla paksha reads Bhadrapada in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 7 Apr 2016, 19:23 Thu. Since then the Sun has moved 150.5° round the stars. Vikram Samvat numbers that year 2073; Shaka Samvat numbers it 1938.
