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, 06:06 here. Navami ended at 07:37 Fri, before it. Dashami ends at 06:59, when the lead reaches 300°. The lead passed 180° at the full moon of 28 Sep, so the Moon is waning: Krishna paksha.

The night of Fri 6 Oct ran from sunset 17:43 Fri 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 17:42, splits into 8 choghadiyas of 1 h 27 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 17:42 to 06:07 Sun, 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′. Ashlesha spans 106°40′–120°00′; the Moon entered its pada 1 at 106°40′. It leaves at 02:05 Sun, for Magha.

Add the Sun's and the Moon's places among the stars: 169.6° + 109.1° = 278.7°. The sum, cut into 27 parts of 13°20′, gives the yoga: 266°40′–280°00′ is the 21st, Siddha. It ends at 08:20, then Sadhya.

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 19:14 Fri, when the lead reached 294°; Vishti runs until 06:59.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:06 to 06:07 Sun, so the hours after midnight still belong to Shaniwara.

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: Simha gives Bhadrapada. The Sun enters Kanya on 17 Sep, inside the month. The next new moon, 12 Oct, finds it in Kanya and begins Ashwina.

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 Oct, with the Sun in Kanya, begins Ashwina. Until then this Krishna paksha reads Ashwina here, and Bhadrapada in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 20 Mar 2034, 13:44 Mon. Since then the Sun has moved 194.1° round the stars. Vikram Samvat numbers that year 2091; Shaka Samvat numbers it 1956.
