Panchang in Ipameri, Goiás, Brazil Sun 16 Oct 2039

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 336°–348° is the 29th, Krishna Chaturdashi. A day takes the tithi in force at its sunrise, 05:43 here. Trayodashi ended at 20:23 Sat, before it. Chaturdashi ends at 18:30, when the lead reaches 348°. The lead passed 180° at the full moon of 2 Oct, so the Moon is waning: Krishna paksha.

The night of Sat 15 Oct ran from sunset 18:13 Sat to sunrise 05:43, 11 h 30 m. Cut into 15 muhurtas of 46 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:43 to 18:13, 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, 18:13 to 05:42 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′. Uttara Phalguni spans 146°40′–160°00′; the Moon entered its pada 4 at 156°40′. It leaves at 06:38, for Hasta.

Add the Sun's and the Moon's places among the stars: 178.4° + 159.5° = 337.9°. The sum, cut into 27 parts of 13°20′, gives the yoga: 333°20′–346°40′ is the 26th, Indra. It ends at 19:39, then Vaidhriti.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Chaturdashi is Vishti and the second Shakuni. Vishti runs until 07:31, when the lead reaches 342°; Shakuni until 18:30.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:43 to 05:42 Mon, so the hours after midnight still belong to Raviwara.

A month normally holds one sankranti, the Sun's entry into a new rashi. From 18 Sep 05:23 Sun to 17 Oct 16:09 Mon the Sun stayed in Kanya, entering Tula at 17 Oct 19:25 Mon, after the new moon. A month with no sankranti is Adhika Ashwina, before Ashwina itself.

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 17 Oct, with the Sun in Kanya, begins Ashwina (Adhik). Until then this Krishna paksha reads Ashwina (Adhik) here, and Ashwina (Adhik) in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 24 Mar 2039, 14:59 Thu. Since then the Sun has moved 198.9° round the stars. Vikram Samvat numbers that year 2096; Shaka Samvat numbers it 1961.
