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, 05:25 here. Ashtami ended at 05:09, before it. Navami ends at 07:27 Tue, when the lead reaches 108°. The lead passed 0° at the new moon of 5 Jun, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise. Navami began at 05:09, before sunrise at 05:25, and ends at 07:27 Tue, after the next sunrise at 05:25 Tue. Both days read Navami: it is a vriddhi tithi here.

The night of Sun 12 Jun ran from sunset 18:09 Sun to sunrise 05:25, 11 h 16 m. Cut into 15 muhurtas of 45 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:25 to 18:09, splits into 8 choghadiyas of 1 h 35 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:09 to 05:25 Tue, splits into 8 choghadiyas of 1 h 24 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′. Uttara Phalguni spans 146°40′–160°00′; the Moon entered its pada 3 at 153°20′. It leaves at 16:46, for Hasta.

Add the Sun's and the Moon's places among the stars: 58.2° + 154.4° = 212.6°. The sum, cut into 27 parts of 13°20′, gives the yoga: 200°00′–213°20′ is the 16th, Siddhi. It ends at 06:48, then Vyatipata.

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 runs until 18:15, when the lead reaches 102°; Kaulava until 07:27 Tue.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:25 to 05:25 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: Vrishabha gives Jyeshtha. The Sun enters Mithuna on 15 Jun, inside the month. The next new moon, 4 Jul, finds it in Mithuna and begins Ashadha.

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 5 Jun, with the Sun in Vrishabha, began Jyeshtha. This Shukla paksha reads Jyeshtha in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 7 Apr 2016, 19:23 Thu. Since then the Sun has moved 64.2° round the stars. Vikram Samvat numbers that year 2073; Shaka Samvat numbers it 1938.
