Panchang in Khmelnytskyi, Ukraine Fri 18 Feb 2011

Purnima follows the tithi at sunrise. Purnima runs from 14:04 on Thu 17 Feb to 10:35 on Fri 18 Feb, so it holds sunrise only on Fri 18 Feb, at 07:16. No text giving Purnima’s time was found; sunrise is Tithika’s convention.

Purnima: every date in Khmelnytskyi

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, 07:16 here. Chaturdashi ended at 14:04 Thu, before it. Purnima ends at 10:35, when the lead reaches 180°. The lead passed 0° at the new moon of 3 Feb, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise. Pratipada began at 10:35 and ended at 06:53 Sat, between the sunrises of 07:16 and 07:14 Sat. Friday reads Purnima and Saturday reads Dwitiya: Pratipada is a kshaya tithi here.

The night of Thu 17 Feb ran from sunset 17:34 Thu to sunrise 07:16, 13 h 42 m. Cut into 15 muhurtas of 54 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 07:16 to 17:35, splits into 8 choghadiyas of 1 h 17 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 17:35 to 07:14 Sat, splits into 8 choghadiyas of 1 h 42 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′. Magha spans 120°00′–133°20′; the Moon entered its pada 1 at 120°. It leaves at 23:15, for Purva Phalguni.

Add the Sun's and the Moon's places among the stars: 305.2° + 123.2° = 428.4°, one full turn and 68.4°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 66°40′–80°00′ is the 6th, Atiganda. It ends at 00:28 Sat, then Sukarma.

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 00:22, when the lead reached 174°; Bava runs until 10:35.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 07:16 to 07:14 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: Makara gives Magha. The Sun enters Kumbha on 13 Feb, inside the month. The next new moon, 4 Mar, finds it in Kumbha and begins Phalguna.

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 3 Feb, with the Sun in Makara, began Magha. This Shukla paksha reads Magha in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 15 Mar 2010, 23:01 Mon. Since then the Sun has moved 334° round the stars. Vikram Samvat numbers that year 2067; Shaka Samvat numbers it 1932.
