Panchang in Ipameri, Goiás, Brazil Thu 18 Oct 2018

Dussehra’s rites are done in aparahna, the fourth fifth of the day. Dashami runs from 06:59 on Thu 18 Oct to 09:27 on Fri 19 Oct, so only Thursday’s aparahna (13:13–15:43) 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: 96°–108° is the 9th, Shukla Navami. A day takes the tithi in force at its sunrise, 05:42 here. Ashtami ended at 04:20 Wed, before it. Navami ends at 06:59, when the lead reaches 108°. The lead passed 0° at the new moon of 9 Oct, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise. Navami began at 04:20 Wed, before sunrise at 05:42 Wed, and ends at 06:59, after the next sunrise at 05:42. Both days read Navami: it is a vriddhi tithi here.

The night of Wed 17 Oct ran from sunset 18:13 Wed to sunrise 05:42, 11 h 29 m. Cut into 15 muhurtas of 45 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:42 to 18:14, splits into 8 choghadiyas of 1 h 34 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:14 to 05:41 Fri, splits into 8 choghadiyas of 1 h 25 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 16:03, for Dhanishtha.

Add the Sun's and the Moon's places among the stars: 180.8° + 288.2° = 469°, one full turn and 109°. 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 02:11 Fri, then Ganda.

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 ended at 17:39 Wed, when the lead reached 102°; Kaulava runs until 06:59.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:42 to 05:41 Fri, so the hours after midnight still belong to Guruwara.

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, 7 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 9 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: 17 Mar 2018, 10:11 Sat. Since then the Sun has moved 208° round the stars. Vikram Samvat numbers that year 2075; Shaka Samvat numbers it 1940.
