Guru Purnima follows the tithi at sunrise. Purnima runs from 02:01 on Mon 22 Jul to 22:15 on Mon 22 Jul, so it holds sunrise only on Mon 22 Jul, at 05:00. No text giving Guru Purnima’s time was found; sunrise is Tithika’s convention.

Purnima: every date in Myshkin

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, 05:00 here. Chaturdashi ended at 02:01, before it. Purnima ends at 22:15, when the lead reaches 180°. The lead passed 0° at the new moon of 8 Jul, so the Moon is waxing: Shukla paksha.

The night of Sun 21 Jul ran from sunset 22:04 Sun to sunrise 05:00, 6 h 56 m. Cut into 15 muhurtas of 27 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:00 to 22:03, splits into 8 choghadiyas of 2 h 7 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 22:03 to 05:02 Tue, splits into 8 choghadiyas of 52 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′. Purva Ashadha spans 253°20′–266°40′; the Moon entered its pada 4 at 263°20′. It leaves at 07:26, for Uttara Ashadha.

Add the Sun's and the Moon's places among the stars: 95.4° + 265.1° = 360.5°, one full turn and 0.5°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 0°00′–13°20′ is the 1st, Vishkambha. It ends at 00:07 Tue, then Priti.

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 12:08, when the lead reaches 174°; Bava until 22:15.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:00 to 05:02 Tue, so the hours after midnight still belong to Somawara.

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: Mithuna gives Ashadha. The Sun enters Karka on 16 Jul, inside the month. The next new moon, 7 Aug, finds it in Karka and begins Shravana.

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 8 Jul, with the Sun in Mithuna, began Ashadha. This Shukla paksha reads Ashadha in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 10 Apr 2013, 13:35 Wed. Since then the Sun has moved 98.8° round the stars. Vikram Samvat numbers that year 2070; Shaka Samvat numbers it 1935.
