Purnima: every date in Myjava

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 168°–180° is the 15th, Shukla Purnima. A day takes the tithi in force at its sunrise, 05:51 here. Chaturdashi ended at 07:44 Sat, before it. Purnima ends at 09:58, when the lead reaches 180°. The lead passed 0° at the new moon of 4 Apr, so the Moon is waxing: Shukla paksha.

The night of Sat 18 Apr ran from sunset 19:45 Sat to sunrise 05:51, 10 h 6 m. Cut into 15 muhurtas of 40 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:51 to 19:46, splits into 8 choghadiyas of 1 h 44 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 19:46 to 05:49 Mon, splits into 8 choghadiyas of 1 h 15 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′. Chitra spans 173°20′–186°40′; the Moon entered its pada 4 at 183°20′. It leaves at 12:10, for Swati.

Add the Sun's and the Moon's places among the stars: 5.4° + 183.5° = 188.9°. The sum, cut into 27 parts of 13°20′, gives the yoga: 186°40′–200°00′ is the 15th, Vajra. It ends at 02:26 Mon, then Siddhi.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Purnima is Vishti and the second Bava. Vishti ended at 20:50 Sat, when the lead reached 174°; Bava runs until 09:58.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:51 to 05:49 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: Meena gives Chaitra. The Sun enters Mesha on 13 Apr, inside the month. The next new moon, 4 May, 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 4 Apr, with the Sun in Meena, began Chaitra. This Shukla paksha reads Chaitra in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 4 Apr 1981, 22:19 Sat. Since then the Sun has moved 14° round the stars. Vikram Samvat numbers that year 2038; Shaka Samvat numbers it 1903.
