Panchang in Ipameri, Goiás, Brazil Mon 14 Dec 2037

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 84°–96° is the 8th, Shukla Ashtami. A day takes the tithi in force at its sunrise, 05:32 here. Saptami ended at 22:28 Sun, before it. Ashtami ends at 00:57 Tue, when the lead reaches 96°. The lead passed 0° at the new moon of 6 Dec, so the Moon is waxing: Shukla paksha.

The night of Sun 13 Dec ran from sunset 18:42 Sun to sunrise 05:32, 10 h 50 m. Cut into 15 muhurtas of 43 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:32 to 18:43, splits into 8 choghadiyas of 1 h 38 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:43 to 05:32 Tue, splits into 8 choghadiyas of 1 h 21 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′. Purva Bhadrapada spans 320°00′–333°20′; the Moon entered its pada 2 at 323°20′. It leaves at 21:20, for Uttara Bhadrapada.

Add the Sun's and the Moon's places among the stars: 238.3° + 325.5° = 563.8°, one full turn and 203.8°. 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 23:15, then Vyatipata.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Ashtami is Vishti and the second Bava. Vishti runs until 11:42, when the lead reaches 90°; Bava until 00:57 Tue.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:32 to 05:32 Tue, so the hours after midnight still belong to Somawara.

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 15 Dec, inside the month. The next new moon, 5 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 6 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: 16 Mar 2037, 20:36 Mon. Since then the Sun has moved 266° round the stars. Vikram Samvat numbers that year 2094; Shaka Samvat numbers it 1959.
