Panchang in Ipameri, Goiás, Brazil Sat 13 Apr 1935

The Sun enters Mesha at 16:53, between sunrise (06:21) and sunset (18:05): Sat 13 Apr. No text giving Mesha Sankranti’s time was found; sankranti is Tithika’s convention.

Mesha Sankranti: every date in Ipameri

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, 06:21 here. Navami ended at 06:09 Fri, before it. Dashami ends at 08:46, when the lead reaches 120°. The lead passed 0° at the new moon of 3 Apr, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise. Dashami began at 06:09 Fri, before sunrise at 06:21 Fri, and ends at 08:46, after the next sunrise at 06:21. Both days read Dashami: it is a vriddhi tithi here.

The night of Fri 12 Apr ran from sunset 18:06 Fri to sunrise 06:21, 12 h 15 m. Cut into 15 muhurtas of 49 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:21 to 18:05, 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, 18:05 to 06:21 Sun, splits into 8 choghadiyas of 1 h 32 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′. Ashlesha spans 106°40′–120°00′; the Moon entered its pada 4 at 116°40′. It leaves at 09:27, for Magha.

Add the Sun's and the Moon's places among the stars: 359.6° + 118.5° = 478.1°, one full turn and 118.1°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 106°40′–120°00′ is the 9th, Shula. It ends at 10:01, then Ganda.

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 19:27 Fri, when the lead reached 114°; Garaja runs until 08:46.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:21 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, 2 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 3 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: 3 Apr 1935, 09:10 Wed. Since then the Sun has moved 9.7° round the stars. Vikram Samvat numbers that year 1992; Shaka Samvat numbers it 1857.
