Panchang in Khmelnytskyi, Ukraine Thu 1 Oct 2020

Purnima follows the tithi at sunrise. Purnima runs from 21:56 on Wed 30 Sep to 00:05 on Fri 2 Oct, so it holds sunrise only on Thu 1 Oct, at 07:12. 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, 07:12 here. Chaturdashi ended at 21:56 Wed, before it. Purnima ends at 00:05 Fri, when the lead reaches 180°. The lead passed 0° at the new moon of 17 Sep, so the Moon is waxing: Shukla paksha.

The night of Wed 30 Sep ran from sunset 18:52 Wed to sunrise 07:12, 12 h 20 m. Cut into 15 muhurtas of 49 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 07:12 to 18:50, 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 night here, 18:50 to 07:13 Fri, 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 fixed stars divide the Moon's path into 27 nakshatras of 13°20′, each in 4 padas of 3°20′. Uttara Bhadrapada spans 333°20′–346°40′; the Moon entered its pada 1 at 333°20′. It leaves at 03:26 Fri, for Revati.

Add the Sun's and the Moon's places among the stars: 164.3° + 336.6° = 500.9°, one full turn and 140.9°. 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 17:55, 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 runs until 10:59, when the lead reaches 174°; Bava until 00:05 Fri.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 07:12 to 07:13 Fri, so the hours after midnight still belong to Guruwara.

A month normally holds one sankranti, the Sun's entry into a new rashi. From 17 Sep 14:00 Thu to 16 Oct 22:31 Fri the Sun stayed in Kanya, entering Tula at 17 Oct 04:35 Sat, after the new moon. A month with no sankranti is Adhika Ashwina, before Ashwina itself.

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 17 Sep, with the Sun in Kanya, began Ashwina (Adhik). This Shukla paksha reads Ashwina (Adhik) in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 24 Mar 2020, 11:28 Tue. Since then the Sun has moved 184.2° round the stars. Vikram Samvat numbers that year 2077; Shaka Samvat numbers it 1942.
