Panchang in Ipameri, Goiás, Brazil Sat 22 May 1926

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, 06:32 here. Navami ended at 06:20 Fri, before it. Dashami ends at 08:14, when the lead reaches 120°. The lead passed 0° at the new moon of 11 May, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise. Dashami began at 06:20 Fri, before sunrise at 06:32 Fri, and ends at 08:14, after the next sunrise at 06:32. Both days read Dashami: it is a vriddhi tithi here.

The night of Fri 21 May ran from sunset 17:46 Fri to sunrise 06:32, 12 h 46 m. Cut into 15 muhurtas of 51 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:32 to 17:45, splits into 8 choghadiyas of 1 h 24 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 06:32 Sun, splits into 8 choghadiyas of 1 h 35 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′. Uttara Phalguni spans 146°40′–160°00′; the Moon entered its pada 4 at 156°40′. It leaves at 12:37, for Hasta.

Add the Sun's and the Moon's places among the stars: 37.7° + 156.9° = 194.6°. The sum, cut into 27 parts of 13°20′, gives the yoga: 186°40′–200°00′ is the 15th, Vajra. It ends at 16:20, then Siddhi.

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 19:21 Fri, when the lead reached 114°; Garaja runs until 08:14.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:32 to 06:32 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: Mesha gives Vaishakha. The Sun enters Vrishabha on 14 May, inside the month. The next new moon, 10 Jun, finds it in Vrishabha and begins Jyeshtha.

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 11 May, with the Sun in Mesha, began Vaishakha. This Shukla paksha reads Vaishakha in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 12 Apr 1926, 09:56 Mon. Since then the Sun has moved 38.7° round the stars. Vikram Samvat numbers that year 1983; Shaka Samvat numbers it 1848.
