Purnima: every date in Sevan

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, 04:34 here. Chaturdashi ended at 03:30, before it. Purnima ends at 00:40 Thu, when the lead reaches 180°. The lead passed 0° at the new moon of 19 Jun, so the Moon is waxing: Shukla paksha.

Sunrise here, 05:27, came before Chaturdashi ended at 06:00: this day reads Chaturdashi. Purnima ends at 03:10 Thu, before the next sunrise, so no day here reads Purnima: it is kshaya.

Sunrise here, 04:34, came after Chaturdashi ended at 03:30: this day reads Purnima.

The night of Tue 3 Jul ran from sunset 19:34 Tue to sunrise 04:34, 9 h 0 m. Cut into 15 muhurtas of 36 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 04:34 to 19:33, splits into 8 choghadiyas of 1 h 52 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 19:33 to 04:34 Thu, splits into 8 choghadiyas of 1 h 7 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 14:24, for Purva Ashadha.

Add the Sun's and the Moon's places among the stars: 78.8° + 247.4° = 326.2°. The sum, cut into 27 parts of 13°20′, gives the yoga: 320°00′–333°20′ is the 25th, Brahma. It ends at 15:41, then Indra.

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 runs until 14:08, when the lead reaches 174°; Bava until 00:40 Thu.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 04:34 to 04:34 Thu, so the hours after midnight still belong to Budhawara.

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 15 Jul, inside the month. The next new moon, 19 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 19 Jun, 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: 23 Mar 1917, 07:04 Fri. Since then the Sun has moved 99.5° round the stars. Vikram Samvat numbers that year 1974; Shaka Samvat numbers it 1839.
