Panchang in Codcod, Western Visayas, Philippines Sun 29 Nov 1981

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 24°–36° is the 3rd, Shukla Tritiya. A day takes the tithi in force at its sunrise, 05:48 here. Dwitiya ended at 03:54, before it. Tritiya ends at 06:24 Mon, when the lead reaches 36°. The lead passed 0° at the new moon of 26 Nov, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise. Tritiya began at 03:54, before sunrise at 05:48, and ends at 06:24 Mon, after the next sunrise at 05:48 Mon. Both days read Tritiya: it is a vriddhi tithi here.

The night of Sat 28 Nov ran from sunset 17:22 Sat to sunrise 05:48, 12 h 26 m. Cut into 15 muhurtas of 49 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:48 to 17:22, splits into 8 choghadiyas of 1 h 26 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 17:22 to 05:48 Mon, splits into 8 choghadiyas of 1 h 33 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 3 at 246°40′. It leaves at 16:54, for Purva Ashadha.

Add the Sun's and the Moon's places among the stars: 223° + 247.8° = 470.8°, one full turn and 110.8°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 106°40′–120°00′ is the 9th, Shula. It ends at 22:52, then Ganda.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Tritiya is Taitila and the second Garaja. Taitila runs until 17:10, when the lead reaches 30°; Garaja until 06:24 Mon.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:48 to 05:48 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: Vrishchika gives Margashirsha. The Sun enters Dhanu on 15 Dec, inside the month. The next new moon, 26 Dec, finds it in Dhanu and begins Pausha.

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 26 Nov, with the Sun in Vrishchika, began Margashirsha. This Shukla paksha reads Margashirsha in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 5 Apr 1981, 04:19 Sun. Since then the Sun has moved 231.6° round the stars. Vikram Samvat numbers that year 2038; Shaka Samvat numbers it 1903.
