Panchang in Codcod, Western Visayas, Philippines Sun 1 Mar 1981

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, 06:02 here. Navami ended at 23:51 Sat, before it. Dashami ends at 00:48 Mon, when the lead reaches 300°. The lead passed 180° at the full moon of 19 Feb, so the Moon is waning: Krishna paksha.

The night of Sat 28 Feb ran from sunset 17:57 Sat to sunrise 06:02, 12 h 5 m. Cut into 15 muhurtas of 48 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:02 to 17:57, 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, 17:57 to 06:01 Mon, 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′. Mula spans 240°00′–253°20′; the Moon entered its pada 3 at 246°40′. It leaves at 17:02, for Purva Ashadha.

Add the Sun's and the Moon's places among the stars: 316.6° + 247.6° = 564.2°, one full turn and 204.2°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 200°00′–213°20′ is the 16th, Siddhi. It ends at 22:08, then Vyatipata.

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 12:25, when the lead reaches 294°; Vishti until 00:48 Mon.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:02 to 06:01 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: Makara gives Magha. The Sun enters Kumbha on 12 Feb, inside the month. The next new moon, 6 Mar, finds it in Kumbha and begins Phalguna.

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 Mar, with the Sun in Kumbha, begins Phalguna. Until then this Krishna paksha reads Phalguna here, and Magha in the amanta count.

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 343.8° round the stars. Vikram Samvat numbers that year 2037; Shaka Samvat numbers it 1902.
