Panchang in Ipameri, Goiás, Brazil Sun 12 Oct 1986

Dussehra’s rites are done in aparahna, the fourth fifth of the day. Dashami runs from 19:37 on Sat 11 Oct to 18:06 on Sun 12 Oct, so only Sunday’s aparahna (13:14–15:43) falls within it.

Dussehra: every date in Ipameri

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 108°–120° is the 10th, Shukla Dashami. A day takes the tithi in force at its sunrise, 05:46 here. Navami ended at 19:37 Sat, before it. Dashami ends at 18:06, when the lead reaches 120°. The lead passed 0° at the new moon of 3 Oct, so the Moon is waxing: Shukla paksha.

The night of Sat 11 Oct ran from sunset 18:12 Sat to sunrise 05:46, 11 h 34 m. Cut into 15 muhurtas of 46 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:46 to 18:12, 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, 18:12 to 05:45 Mon, 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′. Shravana spans 280°00′–293°20′; the Moon entered its pada 3 at 286°40′. It leaves at 14:11, for Dhanishtha.

Add the Sun's and the Moon's places among the stars: 175.1° + 288.5° = 463.6°, one full turn and 103.6°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 93°20′–106°40′ is the 8th, Dhriti. It ends at 10:48, then Shula.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Dashami is Taitila and the second Garaja. Taitila runs until 06:49, when the lead reaches 114°; Garaja until 18:06.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:46 to 05:45 Mon, so the hours after midnight still belong to Raviwara.

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: Kanya gives Ashwina. The Sun enters Tula on 17 Oct, inside the month. The next new moon, 2 Nov, finds it in Tula and begins Kartika.

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 3 Oct, with the Sun in Kanya, began Ashwina. This Shukla paksha reads Ashwina in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 9 Apr 1986, 03:08 Wed. Since then the Sun has moved 179.7° round the stars. Vikram Samvat numbers that year 2043; Shaka Samvat numbers it 1908.
