Panchang in Codcod, Western Visayas, Philippines Tue 15 Oct 1985

Ghatasthapana is done in pratahkala, the first fifth of the day. Pratipada runs from 12:33 on Mon 14 Oct to 08:57 on Tue 15 Oct, so only Tuesday’s pratahkala (05:35–07:58) falls within it.

Sharad Navratri: every date in Codcod

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 0°–12° is the 1st, Shukla Pratipada. A day takes the tithi in force at its sunrise, 05:35 here. Amavasya ended at 12:33 Mon, before it. Pratipada ends at 08:57, when the lead reaches 12°. The lead passed 0° at the new moon of 14 Oct, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise. Dwitiya began at 08:57 and ended at 05:23 Wed, between the sunrises of 05:35 and 05:36 Wed. Tuesday reads Pratipada and Wednesday reads Tritiya: Dwitiya is a kshaya tithi here.

The night of Mon 14 Oct ran from sunset 17:30 Mon to sunrise 05:35, 12 h 5 m. Cut into 15 muhurtas of 48 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:35 to 17:30, splits into 8 choghadiyas of 1 h 29 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 17:30 to 05:36 Wed, splits into 8 choghadiyas of 1 h 30 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′. Swati spans 186°40′–200°00′; the Moon entered its pada 1 at 186°40′. It leaves at 00:54 Wed, for Vishakha.

Add the Sun's and the Moon's places among the stars: 177.8° + 187.8° = 365.6°, one full turn and 5.6°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 0°00′–13°20′ is the 1st, Vishkambha. It ends at 17:00, then Priti.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Pratipada is Kinstughna and the second Bava. Kinstughna ended at 22:45 Mon, when the lead reached 6°; Bava runs until 08:57.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:35 to 05:36 Wed, so the hours after midnight still belong to Mangalawara.

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: Kanya gives Ashwina. The Sun enters Tula on 17 Oct, inside the month. The next new moon, 12 Nov, finds it in Tula and begins Kartika.

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 14 Oct, with the Sun in Kanya, began Ashwina. This Shukla paksha reads Ashwina in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 21 Mar 1985, 19:58 Thu. Since then the Sun has moved 200.6° round the stars. Vikram Samvat numbers that year 2042; Shaka Samvat numbers it 1907.
