Panchang in Ipameri, Goiás, Brazil Sat 29 Sep 1923

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 216°–228° is the 19th, Krishna Chaturthi. A day takes the tithi in force at its sunrise, 05:57 here. Tritiya ended at 04:55 Fri, before it. Chaturthi ends at 07:25, when the lead reaches 228°. The lead passed 180° at the full moon of 24 Sep, so the Moon is waning: Krishna paksha.

A day takes the tithi in force at its sunrise. Chaturthi began at 04:55 Fri, before sunrise at 05:58 Fri, and ends at 07:25, after the next sunrise at 05:57. Both days read Chaturthi: it is a vriddhi tithi here.

The night of Fri 28 Sep ran from sunset 18:09 Fri to sunrise 05:57, 11 h 48 m. Cut into 15 muhurtas of 47 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:57 to 18:09, splits into 8 choghadiyas of 1 h 31 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:09 to 05:56 Sun, splits into 8 choghadiyas of 1 h 28 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′. Krittika spans 26°40′–40°00′; the Moon entered its pada 1 at 26°40′. It leaves at 02:43 Sun, for Rohini.

Add the Sun's and the Moon's places among the stars: 162.4° + 29.7° = 192.1°. The sum, cut into 27 parts of 13°20′, gives the yoga: 186°40′–200°00′ is the 15th, Vajra. It ends at 20:40, then Siddhi.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Chaturthi is Bava and the second Balava. Bava ended at 18:10 Fri, when the lead reached 222°; Balava runs until 07:25.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:57 to 05:56 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: Simha gives Bhadrapada. The Sun enters Kanya on 16 Sep, inside the month. The next new moon, 10 Oct, finds it in Kanya and begins Ashwina.

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 10 Oct, with the Sun in Kanya, begins Ashwina. Until then this Krishna paksha reads Ashwina here, and Bhadrapada in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 17 Mar 1923, 09:51 Sat. Since then the Sun has moved 189.3° round the stars. Vikram Samvat numbers that year 1980; Shaka Samvat numbers it 1845.
