Panchang in Codcod, Western Visayas, Philippines Sat 19 May 2018

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 36°–48° is the 4th, Shukla Chaturthi. A day takes the tithi in force at its sunrise, 05:24 here. Tritiya ended at 10:54 Fri, before it. Chaturthi ends at 07:58, when the lead reaches 48°. The lead passed 0° at the new moon of 15 May, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise. Panchami began at 07:58 and ended at 05:14 Sun, between the sunrises of 05:24 and 05:24 Sun. Saturday reads Chaturthi and Sunday reads Shashthi: Panchami is a kshaya tithi here.

Sunrise here, 05:28, came after Chaturthi ended at 05:28: this day reads Panchami.

Codcod · UTC+8

Sunrise here, 05:24, came before Chaturthi ended at 07:58: this day reads Chaturthi. Panchami ends at 05:14 Sun, before the next sunrise, so no day here reads Panchami: it is kshaya.

The night of Fri 18 May ran from sunset 18:02 Fri to sunrise 05:24, 11 h 22 m. Cut into 15 muhurtas of 45 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:24 to 18:02, splits into 8 choghadiyas of 1 h 34 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:02 to 05:24 Sun, splits into 8 choghadiyas of 1 h 25 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′. Punarvasu spans 80°00′–93°20′; the Moon entered its pada 1 at 80°. It leaves at 02:55 Sun, for Pushya.

Add the Sun's and the Moon's places among the stars: 33.8° + 80.3° = 114.1°. The sum, cut into 27 parts of 13°20′, gives the yoga: 106°40′–120°00′ is the 9th, Shula. It ends at 14:32, then Ganda.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Chaturthi is Vanija and the second Vishti. Vanija ended at 21:25 Fri, when the lead reached 42°; Vishti runs until 07:58.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:24 to 05:24 Sun, so the hours after midnight still belong to Shaniwara.

A month normally holds one sankranti, the Sun's entry into a new rashi. From 15 May 19:47 Tue to 14 Jun 03:43 Thu the Sun stayed in Vrishabha, entering Mithuna at 15 Jun 14:06 Fri, after the new moon. A month with no sankranti is Adhika Jyeshtha, before Jyeshtha itself.

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 15 May, with the Sun in Vrishabha, began Jyeshtha (Adhik). This Shukla paksha reads Jyeshtha (Adhik) in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 17 Mar 2018, 21:11 Sat. Since then the Sun has moved 61° round the stars. Vikram Samvat numbers that year 2075; Shaka Samvat numbers it 1940.
