Panchang in Ipameri, Goiás, Brazil Sat 29 Oct 2095

The tilak is applied in aparahna, the fourth fifth of the day. Dwitiya runs from 06:02 on Sat 29 Oct to 08:20 on Sun 30 Oct, so only Saturday’s aparahna (13:12–15:45) falls within it. No text giving Bhai Dooj’s time was found; aparahna is Tithika’s convention.

Bhai Dooj: every date in Ipameri

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 0°–12° is the 1st, Shukla Pratipada. A day takes the tithi in force at its sunrise, 05:35 here. Amavasya ended at 03:34 Fri, before it. Pratipada ends at 06:02, when the lead reaches 12°. The lead passed 0° at the new moon of 28 Oct, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise. Pratipada began at 03:34 Fri, before sunrise at 05:35 Fri, and ends at 06:02, after the next sunrise at 05:35. Both days read Pratipada: it is a vriddhi tithi here.

The night of Fri 28 Oct ran from sunset 18:17 Fri to sunrise 05:35, 11 h 18 m. Cut into 15 muhurtas of 45 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:35 to 18:17, splits into 8 choghadiyas of 1 h 35 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:17 to 05:34 Sun, splits into 8 choghadiyas of 1 h 24 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′. Vishakha spans 200°00′–213°20′; the Moon entered its pada 1 at 200°. It leaves at 02:45 Sun, for Anuradha.

Add the Sun's and the Moon's places among the stars: 191° + 202.8° = 393.8°, one full turn and 33.8°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 26°40′–40°00′ is the 3rd, Ayushmana. It ends at 17:04, then Saubhagya.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Pratipada is Kinstughna and the second Bava. Kinstughna ended at 16:49 Fri, when the lead reached 6°; Bava runs until 06:02.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:35 to 05:34 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: Tula gives Kartika. The Sun enters Vrishchika on 17 Nov, inside the month. The next new moon, 26 Nov, finds it in Vrishchika and begins Margashirsha.

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 28 Oct, with the Sun in Tula, began Kartika. This Shukla paksha reads Kartika in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 4 Apr 2095, 13:37 Mon. Since then the Sun has moved 201° round the stars. Vikram Samvat numbers that year 2152; Shaka Samvat numbers it 2017.
