The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 84°–96° is the 8th, Shukla Ashtami. A day takes the tithi in force at its sunrise, 07:10 here. Saptami ended at 06:42 Mon, before it. Ashtami ends at 09:04, when the lead reaches 96°. The lead passed 0° at the new moon of 4 Jul, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise. Ashtami began at 06:42 Mon, before sunrise at 07:09 Mon, and ends at 09:04, after the next sunrise at 07:10. Both days read Ashtami: it is a vriddhi tithi here.

The night of Mon 11 Jul ran from sunset 20:16 Mon to sunrise 07:10, 10 h 54 m. Cut into 15 muhurtas of 43 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 07:10 to 20:16, splits into 8 choghadiyas of 1 h 38 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 20:16 to 07:10 Wed, splits into 8 choghadiyas of 1 h 21 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′. Chitra spans 173°20′–186°40′; the Moon entered its pada 3 at 180°. It leaves at 17:23, for Swati.

Add the Sun's and the Moon's places among the stars: 86.5° + 181.6° = 268.1°. The sum, cut into 27 parts of 13°20′, gives the yoga: 266°40′–280°00′ is the 21st, Siddha. It ends at 05:28 Wed, then Sadhya.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Ashtami is Vishti and the second Bava. Vishti ended at 19:51 Mon, when the lead reached 90°; Bava runs until 09:04.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 07:10 to 07:10 Wed, so the hours after midnight still belong to Mangalawara.

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 15 Jul, inside the month. The next new moon, 2 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 4 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: 7 Apr 2016, 06:23 Thu. Since then the Sun has moved 92.5° round the stars. Vikram Samvat numbers that year 2073; Shaka Samvat numbers it 1938.
