Panchang in Ipameri, Goiás, Brazil Fri 18 Jun 1937

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 108°–120° is the 10th, Shukla Dashami. A day takes the tithi in force at its sunrise, 06:41 here. Navami ended at 06:00 Thu, before it. Dashami ends at 08:01, when the lead reaches 120°. The lead passed 0° at the new moon of 8 Jun, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise. Dashami began at 06:00 Thu, before sunrise at 06:41 Thu, and ends at 08:01, after the next sunrise at 06:41. Both days read Dashami: it is a vriddhi tithi here.

The night of Thu 17 Jun ran from sunset 17:45 Thu to sunrise 06:41, 12 h 56 m. Cut into 15 muhurtas of 51 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:41 to 17:45, splits into 8 choghadiyas of 1 h 23 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 17:45 to 06:41 Sat, splits into 8 choghadiyas of 1 h 37 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′. Chitra spans 173°20′–186°40′; the Moon entered its pada 3 at 180°. It leaves at 13:49, for Swati.

Add the Sun's and the Moon's places among the stars: 63.7° + 183.1° = 246.8°. The sum, cut into 27 parts of 13°20′, gives the yoga: 240°00′–253°20′ is the 19th, Parigha. It ends at 18:46, then Shiva.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Dashami is Taitila and the second Garaja. Taitila ended at 18:57 Thu, when the lead reached 114°; Garaja runs until 08:01.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:41 to 06:41 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 14 Jun, inside the month. The next new moon, 8 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 8 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 1937, 02:09 Sun. Since then the Sun has moved 65.8° round the stars. Vikram Samvat numbers that year 1994; Shaka Samvat numbers it 1859.
