Panchang in Ipameri, Goiás, Brazil Sat 9 Apr 2016

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 24°–36° is the 3rd, Shukla Tritiya. A day takes the tithi in force at its sunrise, 06:20 here. Dwitiya ended at 00:52, before it. Tritiya ends at 21:25, when the lead reaches 36°. The lead passed 0° at the new moon of 7 Apr, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise.

Sunrise here, 06:02, came before Dwitiya ended at 09:22: this day reads Dwitiya. Tritiya ends at 05:55 Sun, before the next sunrise, so no day here reads Tritiya: it is kshaya.

Sunrise here, 06:20, came after Dwitiya ended at 00:52: this day reads Tritiya.

The night of Fri 8 Apr ran from sunset 18:08 Fri to sunrise 06:20, 12 h 12 m. Cut into 15 muhurtas of 48 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:20 to 18:07, 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, 18:07 to 06:21 Sun, 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′. Bharani spans 13°20′–26°40′; the Moon entered its pada 3 at 20°. It leaves at 12:04, for Krittika.

Add the Sun's and the Moon's places among the stars: 355.9° + 23.1° = 379°, one full turn and 19°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 13°20′–26°40′ is the 2nd, Priti. It ends at 17:56, then Ayushmana.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Tritiya is Taitila and the second Garaja. Taitila runs until 11:06, when the lead reaches 30°; Garaja until 21:25.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:20 to 06:21 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: Meena gives Chaitra. The Sun enters Mesha on 13 Apr, inside the month. The next new moon, 6 May, finds it in Mesha and begins Vaishakha.

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 7 Apr, with the Sun in Meena, began Chaitra. This Shukla paksha reads Chaitra in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 7 Apr 2016, 08:23 Thu. Since then the Sun has moved 1.9° round the stars. Vikram Samvat numbers that year 2073; Shaka Samvat numbers it 1938.
