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, 06:36 here. Navami ended at 08:28 Mon, before it. Dashami ends at 09:53, when the lead reaches 300°. The lead passed 180° at the full moon of 31 Aug, so the Moon is waning: Krishna paksha.

The night of Mon 10 Sep ran from sunset 19:17 Mon to sunrise 06:36, 11 h 19 m. Cut into 15 muhurtas of 45 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:36 to 19:15, 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, 19:15 to 06:37 Wed, 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′. Punarvasu spans 80°00′–93°20′; the Moon entered its pada 1 at 80°. It leaves at 02:03 Wed, for Pushya.

Add the Sun's and the Moon's places among the stars: 144.7° + 83.2° = 227.9°. The sum, cut into 27 parts of 13°20′, gives the yoga: 226°40′–240°00′ is the 18th, Variyana. It ends at 04:04 Wed, then Parigha.

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 21:16 Mon, when the lead reached 294°; Vishti runs until 09:53.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:36 to 06:37 Wed, so the hours after midnight still belong to Mangalawara.

A month normally holds one sankranti, the Sun's entry into a new rashi. From 17 Aug 19:54 Fri to 16 Sep 06:10 Sun the Sun stayed in Simha, entering Kanya at 16 Sep 16:24 Sun, after the new moon. A month with no sankranti is Adhika Bhadrapada, before Bhadrapada 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 16 Sep, with the Sun in Simha, begins Bhadrapada (Adhik). Until then this Krishna paksha reads Bhadrapada (Adhik) here, and Bhadrapada (Adhik) in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 22 Mar 2012, 18:37 Thu. Since then the Sun has moved 166.4° round the stars. Vikram Samvat numbers that year 2069; Shaka Samvat numbers it 1934.
