The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 288°–300° is the 25th, Krishna Dashami. A day takes the tithi in force at its sunrise, 05:27 here. Navami ended at 15:52 Wed, before it. Dashami ends at 16:41, when the lead reaches 300°. The lead passed 180° at the full moon of 27 Apr, so the Moon is waning: Krishna paksha.

The night of Wed 5 May ran from sunset 17:59 Wed to sunrise 05:27, 11 h 28 m. Cut into 15 muhurtas of 45 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:27 to 18:00, splits into 8 choghadiyas of 1 h 34 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:00 to 05:27 Fri, 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′. Shatabhisha spans 306°40′–320°00′; the Moon entered its pada 3 at 313°20′. It leaves at 13:02, for Purva Bhadrapada.

Add the Sun's and the Moon's places among the stars: 21.4° + 316° = 337.4°. The sum, cut into 27 parts of 13°20′, gives the yoga: 333°20′–346°40′ is the 26th, Indra. It ends at 21:50, then Vaidhriti.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Dashami is Vanija and the second Vishti. Vanija ended at 04:12, when the lead reached 294°; Vishti runs until 16:41.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:27 to 05:27 Fri, so the hours after midnight still belong to Guruwara.

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: Meena gives Chaitra. The Sun enters Mesha on 14 Apr, inside the month. The next new moon, 12 May, finds it in Mesha and begins Vaishakha.

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 12 May, with the Sun in Mesha, begins Vaishakha. Until then this Krishna paksha reads Vaishakha here, and Chaitra in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 12 Apr 2021, 10:30 Mon. Since then the Sun has moved 23.1° round the stars. Vikram Samvat numbers that year 2078; Shaka Samvat numbers it 1943.
