The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 336°–348° is the 29th, Krishna Chaturdashi. A day takes the tithi in force at its sunrise, 06:09 here. Trayodashi ended at 05:48 Thu, before it. Chaturdashi ends at 07:55, when the lead reaches 348°. The lead passed 180° at the full moon of 6 Apr, so the Moon is waning: Krishna paksha.

A day takes the tithi in force at its sunrise. Chaturdashi began at 05:48 Thu, before sunrise at 06:11 Thu, and ends at 07:55, after the next sunrise at 06:09. Both days read Chaturdashi: it is a vriddhi tithi here.

The night of Thu 19 Apr ran from sunset 20:11 Thu to sunrise 06:09, 9 h 58 m. Cut into 15 muhurtas of 39 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:09 to 20:12, splits into 8 choghadiyas of 1 h 45 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 20:12 to 06:08 Sat, splits into 8 choghadiyas of 1 h 14 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′. Revati spans 346°40′–360°00′; the Moon entered its pada 3 at 353°20′. It leaves at 19:01, for Ashwini.

Add the Sun's and the Moon's places among the stars: 6.4° + 353.6° = 360°, one full turn and 0°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 0°00′–13°20′ is the 1st, Vishkambha. It ends at 06:58 Sat, then Priti.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Chaturdashi is Vishti and the second Shakuni. Vishti ended at 18:49 Thu, when the lead reached 342°; Shakuni runs until 07:55.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:09 to 06:08 Sat, so the hours after midnight still belong to Shukrawara.

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: Meena gives Chaitra. The Sun enters Mesha on 13 Apr, inside the month. The next new moon, 21 Apr, finds it in Mesha and begins Vaishakha.

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 21 Apr, with the Sun in Mesha, begins Vaishakha. Until then this Krishna paksha reads Vaishakha here, and Chaitra in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 22 Mar 2012, 16:37 Thu. Since then the Sun has moved 28.1° round the stars. Vikram Samvat numbers that year 2069; Shaka Samvat numbers it 1934.
