Panchang in Ipameri, Goiás, Brazil Tue 8 Oct 2019

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, 05:49 here. Navami ended at 04:08 Mon, before it. Dashami ends at 06:20, when the lead reaches 120°. The lead passed 0° at the new moon of 28 Sep, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise. Dashami began at 04:08 Mon, before sunrise at 05:50 Mon, and ends at 06:20, after the next sunrise at 05:49. Both days read Dashami: it is a vriddhi tithi here.

The night of Mon 7 Oct ran from sunset 18:11 Mon to sunrise 05:49, 11 h 38 m. Cut into 15 muhurtas of 46 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:49 to 18:11, 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 night here, 18:11 to 05:48 Wed, 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 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 4 at 290°. It leaves at 11:42, for Dhanishtha.

Add the Sun's and the Moon's places among the stars: 170.7° + 290.4° = 461.1°, one full turn and 101.1°. 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 16:14, 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 ended at 17:11 Mon, when the lead reached 114°; Garaja runs until 06:20.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:49 to 05:48 Wed, so the hours after midnight still belong to Mangalawara.

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, 28 Oct, 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 28 Sep, 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: 5 Apr 2019, 05:50 Fri. Since then the Sun has moved 179.5° round the stars. Vikram Samvat numbers that year 2076; Shaka Samvat numbers it 1941.
