Panchang in Codcod, Western Visayas, Philippines Sun 11 Jan 1981

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 48°–60° is the 5th, Shukla Panchami. A day takes the tithi in force at its sunrise, 06:08 here. Chaturthi ended at 12:26 Sat, before it. Panchami ends at 10:54, when the lead reaches 60°. The lead passed 0° at the new moon of 6 Jan, so the Moon is waxing: Shukla paksha.

The night of Sat 10 Jan ran from sunset 17:41 Sat to sunrise 06:08, 12 h 27 m. Cut into 15 muhurtas of 49 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:08 to 17:41, 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, 17:41 to 06:08 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′. Purva Bhadrapada spans 320°00′–333°20′; the Moon entered its pada 2 at 323°20′. It leaves at 21:26, for Uttara Bhadrapada.

Add the Sun's and the Moon's places among the stars: 267° + 324.5° = 591.5°, one full turn and 231.5°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 226°40′–240°00′ is the 18th, Variyana. It ends at 19:50, then Parigha.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Panchami is Bava and the second Balava. Bava ended at 23:42 Sat, when the lead reached 54°; Balava runs until 10:54.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:08 to 06:08 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: Dhanu gives Pausha. The Sun enters Makara on 14 Jan, inside the month. The next new moon, 5 Feb, finds it in Makara and begins Magha.

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 6 Jan, with the Sun in Dhanu, began Pausha. This Shukla paksha reads Pausha in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 17 Mar 1980, 02:55 Mon. Since then the Sun has moved 294.2° round the stars. Vikram Samvat numbers that year 2037; Shaka Samvat numbers it 1902.
