Panchang in Codcod, Western Visayas, Philippines Sun 12 Jul 1981

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 120°–132° is the 11th, Shukla Ekadashi. A day takes the tithi in force at its sunrise, 05:31 here. Dashami ended at 04:12, before it. Ekadashi ends at 06:31 Mon, when the lead reaches 132°. The lead passed 0° at the new moon of 2 Jul, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise. Ekadashi began at 04:12, before sunrise at 05:31, and ends at 06:31 Mon, after the next sunrise at 05:32 Mon. Both days read Ekadashi: it is a vriddhi tithi here.

The night of Sat 11 Jul ran from sunset 18:13 Sat to sunrise 05:31, 11 h 18 m. Cut into 15 muhurtas of 45 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:31 to 18:13, splits into 8 choghadiyas of 1 h 35 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:13 to 05:32 Mon, splits into 8 choghadiyas of 1 h 24 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′. Vishakha spans 200°00′–213°20′; the Moon entered its pada 2 at 203°20′. It leaves at 19:23, for Anuradha.

Add the Sun's and the Moon's places among the stars: 85.9° + 206.5° = 292.4°. The sum, cut into 27 parts of 13°20′, gives the yoga: 280°00′–293°20′ is the 22nd, Sadhya. It ends at 07:23, then Shubha.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Ekadashi is Vanija and the second Vishti. Vanija runs until 17:22, when the lead reaches 126°; Vishti until 06:31 Mon.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:31 to 05:32 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: Mithuna gives Ashadha. The Sun enters Karka on 16 Jul, inside the month. The next new moon, 31 Jul, finds it in Karka and begins Shravana.

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 2 Jul, with the Sun in Mithuna, began Ashadha. This Shukla paksha reads Ashadha in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 5 Apr 1981, 04:19 Sun. Since then the Sun has moved 94.5° round the stars. Vikram Samvat numbers that year 2038; Shaka Samvat numbers it 1903.
