Panchang in Ipameri, Goiás, Brazil Wed 18 Sep 2013

Anant Chaturdashi follows the tithi at sunrise. Chaturdashi runs from 12:28 on Tue 17 Sep to 10:09 on Wed 18 Sep, so it holds sunrise only on Wed 18 Sep, at 06:05. No text giving Anant Chaturdashi’s time was found; sunrise is Tithika’s convention.

Anant Chaturdashi: every date in Ipameri

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 156°–168° is the 14th, Shukla Chaturdashi. A day takes the tithi in force at its sunrise, 06:05 here. Trayodashi ended at 12:28 Tue, before it. Chaturdashi ends at 10:09, when the lead reaches 168°. The lead passed 0° at the new moon of 5 Sep, so the Moon is waxing: Shukla paksha.

The night of Tue 17 Sep ran from sunset 18:08 Tue to sunrise 06:05, 11 h 57 m. Cut into 15 muhurtas of 47 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:05 to 18:08, splits into 8 choghadiyas of 1 h 30 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:08 to 06:04 Thu, splits into 8 choghadiyas of 1 h 29 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′. Shatabhisha spans 306°40′–320°00′; the Moon entered its pada 4 at 316°40′. It leaves at 10:37, for Purva Bhadrapada.

Add the Sun's and the Moon's places among the stars: 151.6° + 317.3° = 468.9°, one full turn and 108.9°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 106°40′–120°00′ is the 9th, Shula. It ends at 23:45, then Ganda.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Chaturdashi is Garaja and the second Vanija. Garaja ended at 23:16 Tue, when the lead reached 162°; Vanija runs until 10:09.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:05 to 06:04 Thu, so the hours after midnight still belong to Budhawara.

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 16 Sep, inside the month. The next new moon, 4 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 5 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: 10 Apr 2013, 06:35 Wed. Since then the Sun has moved 155° round the stars. Vikram Samvat numbers that year 2070; Shaka Samvat numbers it 1935.
