Panchang in Ipameri, Goiás, Brazil Sat 13 Sep 1913

Anant Chaturdashi follows the tithi at sunrise. Chaturdashi holds both sunrises, 06:04 on Sat 13 Sep and 06:03 on Sun 14 Sep. Over two sunrises the Nirnayasindhu takes the first: Sat 13 Sep. 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, 06:10 here. Trayodashi ended at 04:40, before it. Chaturdashi ends at 07:09 Sun, when the lead reaches 168°. The lead passed 0° at the new moon of 31 Aug, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise. Chaturdashi began at 04:40, before sunrise at 06:10, and ends at 07:09 Sun, after the next sunrise at 06:09 Sun. Both days read Chaturdashi: it is a vriddhi tithi here.

The night of Fri 12 Sep ran from sunset 18:07 Fri to sunrise 06:10, 12 h 4 m. Cut into 15 muhurtas of 48 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:10 to 18:07, 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 night here, 18:07 to 06:09 Sun, 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 fixed stars divide the Moon's path into 27 nakshatras of 13°20′, each in 4 padas of 3°20′. Dhanishtha spans 293°20′–306°40′; the Moon entered its pada 4 at 303°20′. It leaves at 11:34, for Shatabhisha.

Add the Sun's and the Moon's places among the stars: 147.3° + 304° = 451.3°, one full turn and 91.3°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 80°00′–93°20′ is the 7th, Sukarma. It ends at 09:57, then Dhriti.

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 runs until 17:53, when the lead reaches 162°; Vanija until 07:09 Sun.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:10 to 06:09 Sun, so the hours after midnight still belong to Shaniwara.

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, 30 Sep, 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 31 Aug, 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: 6 Apr 1913, 14:47 Sun. Since then the Sun has moved 153.6° round the stars. Vikram Samvat numbers that year 1970; Shaka Samvat numbers it 1835.
