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, 06:06 here. Tritiya ended at 05:50 Sun, before it. Chaturthi ends at 07:48, when the lead reaches 48°. The lead passed 0° at the new moon of 2 Oct, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise. Chaturthi began at 05:50 Sun, before sunrise at 06:05 Sun, and ends at 07:48, after the next sunrise at 06:06. Both days read Chaturthi: it is a vriddhi tithi here.

The night of Sun 6 Oct ran from sunset 17:43 Sun to sunrise 06:06, 12 h 23 m. Cut into 15 muhurtas of 49 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:06 to 17:41, splits into 8 choghadiyas of 1 h 26 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 17:41 to 06:07 Tue, splits into 8 choghadiyas of 1 h 33 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′. Anuradha spans 213°20′–226°40′; the Moon entered its pada 2 at 216°40′. It leaves at 00:25 Tue, for Jyeshtha.

Add the Sun's and the Moon's places among the stars: 170.1° + 217.3° = 387.4°, one full turn and 27.4°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 26°40′–40°00′ is the 3rd, Ayushmana. It ends at 04:50 Tue, then Saubhagya.

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 18:52 Sun, when the lead reached 42°; Vishti runs until 07:48.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:06 to 06:07 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: Kanya gives Ashwina. The Sun enters Tula on 17 Oct, inside the month. The next new moon, 1 Nov, finds it in Tula and begins Kartika.

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 2 Oct, with the Sun in Kanya, began Ashwina. This Shukla paksha reads Ashwina in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 8 Apr 2024, 21:50 Mon. Since then the Sun has moved 174.9° round the stars. Vikram Samvat numbers that year 2081; Shaka Samvat numbers it 1946.
