Panchang in Codcod, Western Visayas, Philippines Fri 18 Apr 2014

The Sankashti fast is broken at moonrise. Chaturthi runs from 12:51 on Fri 18 Apr to 11:11 on Sat 19 Apr, so it holds moonrise only on Fri 18 Apr, at 20:45. No text giving Sankashti Chaturthi’s time was found; moonrise is Tithika’s convention.

Sankashti Chaturthi: every date in Codcod

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 204°–216° is the 18th, Krishna Tritiya. A day takes the tithi in force at its sunrise, 05:35 here. Dwitiya ended at 14:12 Thu, before it. Tritiya ends at 12:51, when the lead reaches 216°. The lead passed 180° at the full moon of 15 Apr, so the Moon is waning: Krishna paksha.

The night of Thu 17 Apr ran from sunset 17:58 Thu to sunrise 05:35, 11 h 37 m. Cut into 15 muhurtas of 46 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:35 to 17:58, 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 night here, 17:58 to 05:34 Sat, 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 fixed stars divide the Moon's path into 27 nakshatras of 13°20′, each in 4 padas of 3°20′. Anuradha spans 213°20′–226°40′; the Moon entered its pada 1 at 213°20′. It leaves at 00:22 Sat, for Jyeshtha.

Add the Sun's and the Moon's places among the stars: 3.7° + 215.9° = 219.6°. The sum, cut into 27 parts of 13°20′, gives the yoga: 213°20′–226°40′ is the 17th, Vyatipata. It ends at 17:05, then Variyana.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Tritiya is Vanija and the second Vishti. Vanija ended at 01:34, when the lead reached 210°; Vishti runs until 12:51.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:35 to 05:34 Sat, so the hours after midnight still belong to Shukrawara.

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: Meena gives Chaitra. The Sun enters Mesha on 14 Apr, inside the month. The next new moon, 29 Apr, finds it in Mesha and begins Vaishakha.

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 29 Apr, with the Sun in Mesha, begins Vaishakha. Until then this Krishna paksha reads Vaishakha here, and Chaitra in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 31 Mar 2014, 02:44 Mon. Since then the Sun has moved 17.8° round the stars. Vikram Samvat numbers that year 2071; Shaka Samvat numbers it 1936.
