Panchang in Codcod, Western Visayas, Philippines Sun 13 Nov 2016

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 156°–168° is the 14th, Shukla Chaturdashi. A day takes the tithi in force at its sunrise, 05:41 here. Trayodashi ended at 05:31, before it. Chaturdashi ends at 01:47 Mon, when the lead reaches 168°. The lead passed 0° at the new moon of 31 Oct, so the Moon is waxing: Shukla paksha.

The night of Sat 12 Nov ran from sunset 17:21 Sat to sunrise 05:41, 12 h 20 m. Cut into 15 muhurtas of 49 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:41 to 17:21, 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 night here, 17:21 to 05:42 Mon, 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 fixed stars divide the Moon's path into 27 nakshatras of 13°20′, each in 4 padas of 3°20′. Ashwini spans 0°00′–13°20′; the Moon entered its pada 1 at 0°. It leaves at 22:05, for Bharani.

Add the Sun's and the Moon's places among the stars: 206.9° + 2.9° = 209.8°. The sum, cut into 27 parts of 13°20′, gives the yoga: 200°00′–213°20′ is the 16th, Siddhi. It ends at 10:57, then Vyatipata.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Chaturdashi is Garaja and the second Vanija. Garaja runs until 15:42, when the lead reaches 162°; Vanija until 01:47 Mon.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:41 to 05:42 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: Tula gives Kartika. The Sun enters Vrishchika on 16 Nov, inside the month. The next new moon, 29 Nov, finds it in Vrishchika and begins Margashirsha.

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 31 Oct, with the Sun in Tula, began Kartika. This Shukla paksha reads Kartika 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 212.9° round the stars. Vikram Samvat numbers that year 2073; Shaka Samvat numbers it 1938.
