Panchang in Ipameri, Goiás, Brazil Wed 25 Oct 1911

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 36°–48° is the 4th, Shukla Chaturthi. A day takes the tithi in force at its sunrise, 05:38 here. Tritiya ended at 05:00, before it. Chaturthi ends at 07:11 Thu, when the lead reaches 48°. The lead passed 0° at the new moon of 22 Oct, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise. Chaturthi began at 05:00, before sunrise at 05:38, and ends at 07:11 Thu, after the next sunrise at 05:37 Thu. Both days read Chaturthi: it is a vriddhi tithi here.

The night of Tue 24 Oct ran from sunset 18:15 Tue to sunrise 05:38, 11 h 22 m. Cut into 15 muhurtas of 45 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:38 to 18:16, splits into 8 choghadiyas of 1 h 34 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:16 to 05:37 Thu, splits into 8 choghadiyas of 1 h 25 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′. Anuradha spans 213°20′–226°40′; the Moon entered its pada 4 at 223°20′. It leaves at 09:59, for Jyeshtha.

Add the Sun's and the Moon's places among the stars: 188.2° + 224.5° = 412.7°, one full turn and 52.7°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 40°00′–53°20′ is the 4th, Saubhagya. It ends at 06:50, then Shobhana.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Chaturthi is Vanija and the second Vishti. Vanija runs until 18:03, when the lead reaches 42°; Vishti until 07:11 Thu.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:38 to 05:37 Thu, so the hours after midnight still belong to Budhawara.

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 15 Nov, inside the month. The next new moon, 20 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 22 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: 30 Mar 1911, 09:37 Thu. Since then the Sun has moved 202.1° round the stars. Vikram Samvat numbers that year 1968; Shaka Samvat numbers it 1833.
