Panchang in Codcod, Western Visayas, Philippines Sun 21 Aug 2022

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 288°–300° is the 25th, Krishna Dashami. A day takes the tithi in force at its sunrise, 05:37 here. Navami ended at 03:39, before it. Dashami ends at 06:06 Mon, when the lead reaches 300°. The lead passed 180° at the full moon of 12 Aug, so the Moon is waning: Krishna paksha.

A day takes the tithi in force at its sunrise. Dashami began at 03:39, before sunrise at 05:37, and ends at 06:06 Mon, after the next sunrise at 05:37 Mon. Both days read Dashami: it is a vriddhi tithi here.

The night of Sat 20 Aug ran from sunset 18:03 Sat to sunrise 05:37, 11 h 34 m. Cut into 15 muhurtas of 46 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:37 to 18:02, 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 night here, 18:02 to 05:37 Mon, 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 fixed stars divide the Moon's path into 27 nakshatras of 13°20′, each in 4 padas of 3°20′. Rohini spans 40°00′–53°20′; the Moon entered its pada 4 at 50°. It leaves at 07:09, for Mrigashira.

Add the Sun's and the Moon's places among the stars: 123.7° + 52.6° = 176.3°. The sum, cut into 27 parts of 13°20′, gives the yoga: 173°20′–186°40′ is the 14th, Harshana. It ends at 01:07 Mon, then Vajra.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Dashami is Vanija and the second Vishti. Vanija runs until 16:51, when the lead reaches 294°; Vishti until 06:06 Mon.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:37 to 05:37 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: Karka gives Shravana. The Sun enters Simha on 17 Aug, inside the month. The next new moon, 27 Aug, finds it in Simha and begins Bhadrapada.

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 27 Aug, with the Sun in Simha, begins Bhadrapada. Until then this Krishna paksha reads Bhadrapada here, and Shravana in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 1 Apr 2022, 14:24 Fri. Since then the Sun has moved 136.4° round the stars. Vikram Samvat numbers that year 2079; Shaka Samvat numbers it 1944.
