Panchang in Ipameri, Goiás, Brazil Thu 15 Dec 1921

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 180°–192° is the 16th, Krishna Pratipada. A day takes the tithi in force at its sunrise, 05:32 here. Purnima ended at 23:50 Wed, before it. Pratipada ends at 21:20, when the lead reaches 192°. The lead passed 180° at the full moon of 14 Dec, so the Moon is waning: Krishna paksha.

A day takes the tithi in force at its sunrise.

Sunrise here, 07:06, came before Purnima ended at 08:20: this day reads Purnima. Pratipada ends at 05:50 Fri, before the next sunrise, so no day here reads Pratipada: it is kshaya.

Sunrise here, 05:32, came after Purnima ended at 23:50 Wed: this day reads Pratipada.

The night of Wed 14 Dec ran from sunset 18:42 Wed 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 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′. Mrigashira spans 53°20′–66°40′; the Moon entered its pada 3 at 60°. It leaves at 11:15, for Ardra.

Add the Sun's and the Moon's places among the stars: 240.1° + 63.2° = 303.3°. The sum, cut into 27 parts of 13°20′, gives the yoga: 293°20′–306°40′ is the 23rd, Shubha. It ends at 10:44, then Shukla.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Pratipada is Balava and the second Kaulava. Balava runs until 10:38, when the lead reaches 186°; Kaulava until 21:20.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:32 to 05:32 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 15 Dec, inside the month. The next new moon, 29 Dec, 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 29 Dec, 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: 8 Apr 1921, 06:04 Fri. Since then the Sun has moved 244.9° round the stars. Vikram Samvat numbers that year 1978; Shaka Samvat numbers it 1843.
