Panchang in Myjava, Trenčín Region, Slovakia Fri 24 Mar 1978

Purnima follows the tithi at sunrise. Purnima runs from 17:39 on Thu 23 Mar to 17:19 on Fri 24 Mar, so it holds sunrise only on Fri 24 Mar, at 05:45. No text giving Purnima’s time was found; sunrise is Tithika’s convention.

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, 05:45 here. Chaturdashi ended at 17:39 Thu, before it. Purnima ends at 17:19, when the lead reaches 180°. The lead passed 0° at the new moon of 9 Mar, so the Moon is waxing: Shukla paksha.

The night of Thu 23 Mar ran from sunset 18:06 Thu to sunrise 05:45, 11 h 39 m. Cut into 15 muhurtas of 46 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:45 to 18:07, splits into 8 choghadiyas of 1 h 32 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:07 to 05:43 Sat, splits into 8 choghadiyas of 1 h 27 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′. Uttara Phalguni spans 146°40′–160°00′; the Moon entered its pada 3 at 153°20′. It leaves at 17:07, for Hasta.

Add the Sun's and the Moon's places among the stars: 339.7° + 153.7° = 493.4°, one full turn and 133.4°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 133°20′–146°40′ is the 11th, Vriddhi. It ends at 04:06 Sat, then Dhruva.

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 05:33, when the lead reached 174°; Bava runs until 17:19.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:45 to 05:43 Sat, so the hours after midnight still belong to Shukrawara.

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: Kumbha gives Phalguna. The Sun enters Meena on 14 Mar, inside the month. The next new moon, 7 Apr, finds it in Meena and begins Chaitra.

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 9 Mar, with the Sun in Kumbha, began Phalguna. This Shukla paksha reads Phalguna in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 19 Mar 1977, 19:32 Sat. Since then the Sun has moved 364.2° round the stars. Vikram Samvat numbers that year 2034; Shaka Samvat numbers it 1899.
