Panchang in Ipameri, Goiás, Brazil Thu 30 Dec 1920

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 240°–252° is the 21st, Krishna Shashthi. A day takes the tithi in force at its sunrise, 05:40 here. Panchami ended at 16:41 Wed, before it. Shashthi ends at 14:51, when the lead reaches 252°. The lead passed 180° at the full moon of 25 Dec, so the Moon is waning: Krishna paksha.

The night of Wed 29 Dec ran from sunset 18:50 Wed to sunrise 05:40, 10 h 50 m. Cut into 15 muhurtas of 43 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:40 to 18:50, 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, 18:50 to 05:40 Fri, 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 Phalguni spans 133°20′–146°40′; the Moon entered its pada 3 at 140°. It leaves at 12:31, for Uttara Phalguni.

Add the Sun's and the Moon's places among the stars: 255.6° + 142.7° = 398.3°, one full turn and 38.3°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 26°40′–40°00′ is the 3rd, Ayushmana. It ends at 08:21, then Saubhagya.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Shashthi is Garaja and the second Vanija. Garaja ended at 03:40, when the lead reached 246°; Vanija runs until 14:51.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:40 to 05:40 Fri, so the hours after midnight still belong to Guruwara.

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 14 Dec, inside the month. The next new moon, 9 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 9 Jan, with the Sun in Dhanu, begins Pausha. Until then this Krishna paksha reads Pausha here, and Margashirsha in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 20 Mar 1920, 07:55 Sat. Since then the Sun has moved 278.8° round the stars. Vikram Samvat numbers that year 1977; Shaka Samvat numbers it 1842.
