Panchang in Ipameri, Goiás, Brazil Fri 13 Apr 1962

The Sun enters Mesha at 15:00, between sunrise (06:21) and sunset (18:05): Fri 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: 96°–108° is the 9th, Shukla Navami. A day takes the tithi in force at its sunrise, 06:21 here. Ashtami ended at 05:34 Thu, before it. Navami ends at 07:32, when the lead reaches 108°. The lead passed 0° at the new moon of 4 Apr, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise. Navami began at 05:34 Thu, before sunrise at 06:21 Thu, and ends at 07:32, after the next sunrise at 06:21. Both days read Navami: it is a vriddhi tithi here.

The night of Thu 12 Apr ran from sunset 18:05 Thu to sunrise 06:21, 12 h 16 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 Sat, 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 1 at 106°40′. It leaves at 08:23 Sat, for Magha.

Add the Sun's and the Moon's places among the stars: 359.6° + 107.1° = 466.7°, one full turn and 106.7°. 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 07:03 Sat, then Ganda.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Navami is Balava and the second Kaulava. Balava ended at 18:29 Thu, when the lead reached 102°; Kaulava runs until 07:32.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:21 to 06:21 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: Meena gives Chaitra. The Sun enters Mesha on 13 Apr, inside the month. The next new moon, 4 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 4 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: 4 Apr 1962, 16:44 Wed. Since then the Sun has moved 8.4° round the stars. Vikram Samvat numbers that year 2019; Shaka Samvat numbers it 1884.
