The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 36°–48° is the 4th, Shukla Chaturthi. A day takes the tithi in force at its sunrise, 05:47 here. Tritiya ended at 05:28 Fri, before it. Chaturthi ends at 07:56, when the lead reaches 48°. The lead passed 0° at the new moon of 17 Jul, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise. Chaturthi began at 05:28 Fri, before sunrise at 05:46 Fri, and ends at 07:56, after the next sunrise at 05:47. Both days read Chaturthi: it is a vriddhi tithi here.

The night of Fri 21 Jul ran from sunset 20:25 Fri to sunrise 05:47, 9 h 22 m. Cut into 15 muhurtas of 37 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:47 to 20:24, splits into 8 choghadiyas of 1 h 49 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 20:24 to 05:48 Sun, splits into 8 choghadiyas of 1 h 10 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 Phalguni spans 133°20′–146°40′; the Moon entered its pada 3 at 140°. It leaves at 15:28, for Uttara Phalguni.

Add the Sun's and the Moon's places among the stars: 94.9° + 141.9° = 236.8°. The sum, cut into 27 parts of 13°20′, gives the yoga: 226°40′–240°00′ is the 18th, Variyana. It ends at 11:53, then Parigha.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Chaturthi is Vanija and the second Vishti. Vanija ended at 18:43 Fri, when the lead reached 42°; Vishti runs until 07:56.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:47 to 05:48 Sun, so the hours after midnight still belong to Shaniwara.

A month normally holds one sankranti, the Sun's entry into a new rashi. From 17 Jul 22:31 Mon to 16 Aug 13:38 Wed the Sun stayed in Karka, entering Simha at 17 Aug 12:02 Thu, after the new moon. A month with no sankranti is Adhika Shravana, before Shravana 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 Jul, with the Sun in Karka, began Shravana (Adhik). This Shukla paksha reads Shravana (Adhik) in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 21 Mar 2023, 21:23 Tue. Since then the Sun has moved 118.3° round the stars. Vikram Samvat numbers that year 2080; Shaka Samvat numbers it 1945.
