The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 96°–108° is the 9th, Shukla Navami. A day takes the tithi in force at its sunrise, 06:30 here. Ashtami ended at 14:14 Mon, before it. Navami ends at 16:34, when the lead reaches 108°. The lead passed 0° at the new moon of 9 Sep, so the Moon is waxing: Shukla paksha.

The night of Mon 17 Sep ran from sunset 18:58 Mon to sunrise 06:30, 11 h 32 m. Cut into 15 muhurtas of 46 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:30 to 18:56, 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 night here, 18:56 to 06:31 Wed, 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 fixed stars divide the Moon's path into 27 nakshatras of 13°20′, each in 4 padas of 3°20′. Purva Ashadha spans 253°20′–266°40′; the Moon entered its pada 1 at 253°20′. It leaves at 07:05 Wed, for Uttara Ashadha.

Add the Sun's and the Moon's places among the stars: 151.1° + 254.5° = 405.6°, one full turn and 45.6°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 40°00′–53°20′ is the 4th, Saubhagya. It ends at 20:53, then Shobhana.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Navami is Balava and the second Kaulava. Balava ended at 03:21, when the lead reached 102°; Kaulava runs until 16:34.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:30 to 06:31 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: Simha gives Bhadrapada. The Sun enters Kanya on 17 Sep, inside the month. The next new moon, 9 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 9 Sep, with the Sun in Simha, began Bhadrapada. This Shukla paksha reads Bhadrapada in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 17 Mar 2018, 14:11 Sat. Since then the Sun has moved 178.3° round the stars. Vikram Samvat numbers that year 2075; Shaka Samvat numbers it 1940.
