Panchang in Davinópolis, Maranhão, Brazil Fri 13 Jun 1975

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, 06:15 here. Tritiya ended at 10:38 Thu, before it. Chaturthi ends at 08:20, when the lead reaches 48°. The lead passed 0° at the new moon of 9 Jun, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise. Panchami began at 08:20 and ended at 05:56 Sat, between the sunrises of 06:15 and 06:15 Sat. Friday reads Chaturthi and Saturday reads Shashthi: Panchami is a kshaya tithi here.

The night of Thu 12 Jun ran from sunset 18:03 Thu to sunrise 06:15, 12 h 12 m. Cut into 15 muhurtas of 48 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:15 to 18:03, 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 night here, 18:03 to 06:15 Sat, 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 fixed stars divide the Moon's path into 27 nakshatras of 13°20′, each in 4 padas of 3°20′. Pushya spans 93°20′–106°40′; the Moon entered its pada 4 at 103°20′. It leaves at 08:55, for Ashlesha.

Add the Sun's and the Moon's places among the stars: 58.2° + 105.1° = 163.3°. The sum, cut into 27 parts of 13°20′, gives the yoga: 160°00′–173°20′ is the 13th, Vyaghata. It ends at 22:01, then Harshana.

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 ended at 21:30 Thu, when the lead reached 42°; Vishti runs until 08:20.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:15 to 06:15 Sat, so the hours after midnight still belong to Shukrawara.

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: Vrishabha gives Jyeshtha. The Sun enters Mithuna on 15 Jun, inside the month. The next new moon, 9 Jul, finds it in Mithuna and begins Ashadha.

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 9 Jun, with the Sun in Vrishabha, began Jyeshtha. This Shukla paksha reads Jyeshtha in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 11 Apr 1975, 13:38 Fri. Since then the Sun has moved 60.5° round the stars. Vikram Samvat numbers that year 2032; Shaka Samvat numbers it 1897.
