Panchang in Thazhecode, Kerala Wed 27 Jun 2018

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 156°–168° is the 14th, Shukla Chaturdashi. A day takes the tithi in force at its sunrise, 06:05 here. Trayodashi ended at 06:22 Tue, before it. Chaturdashi ends at 08:13, when the lead reaches 168°. The lead passed 0° at the new moon of 14 Jun, so the Moon is waxing: Shukla paksha.

The night of Tue 26 Jun ran from sunset 18:52 Tue to sunrise 06:05, 11 h 13 m. Cut into 15 muhurtas of 44 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:05 to 18:52, 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, 18:52 to 06:05 Thu, 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′. Jyeshtha spans 226°40′–240°00′; the Moon entered its pada 4 at 236°40′. It leaves at 09:34, for Mula.

Add the Sun's and the Moon's places among the stars: 71.2° + 238.3° = 309.5°. The sum, cut into 27 parts of 13°20′, gives the yoga: 306°40′–320°00′ is the 24th, Shukla. It ends at 01:35 Thu, then Brahma.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Chaturdashi is Garaja and the second Vanija. Garaja ended at 19:15 Tue, when the lead reached 162°; Vanija runs until 08:13.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:05 to 06:05 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: Vrishabha gives Jyeshtha. The Sun enters Mithuna on 15 Jun, inside the month. The next new moon, 13 Jul, finds it in Mithuna and begins Ashadha.

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 14 Jun, with the Sun in Vrishabha, began Jyeshtha. This Shukla paksha reads Jyeshtha in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 17 Mar 2018, 18:41 Sat. Since then the Sun has moved 98.4° round the stars. Vikram Samvat numbers that year 2075; Shaka Samvat numbers it 1940.
