Panchang in Davinópolis, Maranhão, Brazil Tue 13 Dec 1983

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, 05:50 here. Ashtami ended at 23:17 Mon, before it. Navami ends at 01:14 Wed, when the lead reaches 108°. The lead passed 0° at the new moon of 4 Dec, so the Moon is waxing: Shukla paksha.

The night of Mon 12 Dec ran from sunset 18:16 Mon to sunrise 05:50, 11 h 34 m. Cut into 15 muhurtas of 46 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:50 to 18:16, splits into 8 choghadiyas of 1 h 33 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:16 to 05:50 Wed, splits into 8 choghadiyas of 1 h 26 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 Bhadrapada spans 333°20′–346°40′; the Moon entered its pada 1 at 333°20′. It leaves at 02:36 Wed, for Revati.

Add the Sun's and the Moon's places among the stars: 237.1° + 336.2° = 573.3°, one full turn and 213.3°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 200°00′–213°20′ is the 16th, Siddhi. It ends at 05:54, then Vyatipata.

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 runs until 12:19, when the lead reaches 102°; Kaulava until 01:14 Wed.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:50 to 05:50 Wed, so the hours after midnight still belong to Mangalawara.

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: Vrishchika gives Margashirsha. The Sun enters Dhanu on 16 Dec, inside the month. The next new moon, 3 Jan, finds it in Dhanu and begins Pausha.

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 Dec, with the Sun in Vrishchika, began Margashirsha. This Shukla paksha reads Margashirsha in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 13 Apr 1983, 04:58 Wed. Since then the Sun has moved 237.9° round the stars. Vikram Samvat numbers that year 2040; Shaka Samvat numbers it 1905.
