Panchang in Ipameri, Goiás, Brazil Fri 2 Oct 2020

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 180°–192° is the 16th, Krishna Pratipada. A day takes the tithi in force at its sunrise, 05:53 here. Purnima ended at 18:05 Thu, before it. Pratipada ends at 20:27, when the lead reaches 192°. The lead passed 180° at the full moon of 1 Oct, so the Moon is waning: Krishna paksha.

The night of Thu 1 Oct ran from sunset 18:10 Thu to sunrise 05:53, 11 h 43 m. Cut into 15 muhurtas of 46 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:53 to 18:10, 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, 18:10 to 05:52 Sat, 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′. Revati spans 346°40′–360°00′; the Moon entered its pada 2 at 350°. It leaves at 00:20 Sat, for Ashwini.

Add the Sun's and the Moon's places among the stars: 165.5° + 350.9° = 516.4°, one full turn and 156.4°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 146°40′–160°00′ is the 12th, Dhruva. It ends at 12:42, then Vyaghata.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Pratipada is Balava and the second Kaulava. Balava runs until 07:14, when the lead reaches 186°; Kaulava until 20:27.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:53 to 05:52 Sat, so the hours after midnight still belong to Shukrawara.

A month normally holds one sankranti, the Sun's entry into a new rashi. From 17 Sep 08:00 Thu to 16 Oct 16:31 Fri the Sun stayed in Kanya, entering Tula at 16 Oct 22:35 Fri, 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 16 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 2020, 06:28 Tue. Since then the Sun has moved 185.4° round the stars. Vikram Samvat numbers that year 2077; Shaka Samvat numbers it 1942.
