Panchang in Ipameri, Goiás, Brazil Sat 14 Apr 2091

The Sun enters Mesha at 16:46, between sunrise (06:21) and sunset (18:03): Sat 14 Apr. No text giving Mesha Sankranti’s time was found; sankranti is Tithika’s convention.

Mesha Sankranti: every date in Ipameri

Smartas test Ekadashi at sunrise. It holds both sunrises, 06:21 on Fri 13 Apr and 06:21 on Sat 14 Apr. Ekadashi (06:12 Fri 13 Apr to 08:14 Sat 14 Apr) and Dwadashi (08:14 Sat 14 Apr to 10:37 Sun 15 Apr) are both longer than their day; when both grow, Smartas take the later day: Sat 14 Apr. Vaishnavas test arunodaya: on Fri 13 Apr Dashami lasts until 06:12, inside it (04:45–06:21); on Sat 14 Apr Ekadashi holds all of it.

Varuthini Ekadashi: every date in Ipameri

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 300°–312° is the 26th, Krishna Ekadashi. A day takes the tithi in force at its sunrise, 06:21 here. Dashami ended at 06:12 Fri, before it. Ekadashi ends at 08:14, when the lead reaches 312°. The lead passed 180° at the full moon of 3 Apr, so the Moon is waning: Krishna paksha.

A day takes the tithi in force at its sunrise. Ekadashi began at 06:12 Fri, before sunrise at 06:21 Fri, and ends at 08:14, after the next sunrise at 06:21. Both days read Ekadashi: it is a vriddhi tithi here.

The night of Fri 13 Apr ran from sunset 18:04 Fri to sunrise 06:21, 12 h 17 m. Cut into 15 muhurtas of 49 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:21 to 18:03, splits into 8 choghadiyas of 1 h 27 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:03 to 06:22 Sun, splits into 8 choghadiyas of 1 h 32 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 2 at 310°. It leaves at 01:03 Sun, for Purva Bhadrapada.

Add the Sun's and the Moon's places among the stars: 359.6° + 310.7° = 670.3°, one full turn and 310.3°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 306°40′–320°00′ is the 24th, Shukla. It ends at 00:25 Sun, then Brahma.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Ekadashi is Bava and the second Balava. Bava ended at 19:10 Fri, when the lead reached 306°; Balava runs until 08:14.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:21 to 06:22 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: Meena gives Chaitra. The Sun enters Mesha on 14 Apr, inside the month. The next new moon, 18 Apr, finds it in Mesha and begins Vaishakha.

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 18 Apr, with the Sun in Mesha, begins Vaishakha. Until then this Krishna paksha reads Vaishakha here, and Chaitra in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 20 Mar 2091, 00:47 Tue. Since then the Sun has moved 24.9° round the stars. Vikram Samvat numbers that year 2148; Shaka Samvat numbers it 2013.
