Panchang in Thazhecode, Kerala Sat 18 May 2019

Buddha Purnima follows the tithi at sunrise. Purnima runs from 04:11 on Sat 18 May to 02:41 on Sun 19 May, so it holds sunrise only on Sat 18 May, at 06:02. No text giving Buddha Purnima’s time was found; sunrise is Tithika’s convention.

Purnima: every date in Thazhecode

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, 06:02 here. Chaturdashi ended at 04:11, before it. Purnima ends at 02:41 Sun, when the lead reaches 180°. The lead passed 0° at the new moon of 5 May, so the Moon is waxing: Shukla paksha.

The night of Fri 17 May ran from sunset 18:42 Fri to sunrise 06:02, 11 h 20 m. Cut into 15 muhurtas of 45 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:02 to 18:42, 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, 18:42 to 06:02 Sun, splits into 8 choghadiyas of 1 h 25 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 1 at 200°. It leaves at 02:21 Sun, for Anuradha.

Add the Sun's and the Moon's places among the stars: 32.7° + 201.7° = 234.4°. The sum, cut into 27 parts of 13°20′, gives the yoga: 226°40′–240°00′ is the 18th, Variyana. It ends at 15:09, then Parigha.

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 15:22, when the lead reaches 174°; Bava until 02:41 Sun.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:02 to 06:02 Sun, so the hours after midnight still belong to Shaniwara.

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: Mesha gives Vaishakha. The Sun enters Vrishabha on 15 May, inside the month. The next new moon, 3 Jun, finds it in Vrishabha and begins Jyeshtha.

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 5 May, with the Sun in Mesha, began Vaishakha. This Shukla paksha reads Vaishakha in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 5 Apr 2019, 14:20 Fri. Since then the Sun has moved 41.5° round the stars. Vikram Samvat numbers that year 2076; Shaka Samvat numbers it 1941.
