Panchang in Ipameri, Goiás, Brazil Mon 2 Jan 1989

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 288°–300° is the 25th, Krishna Dashami. A day takes the tithi in force at its sunrise, 06:42 here. Navami ended at 18:24 Sun, before it. Dashami ends at 20:00, when the lead reaches 300°. The lead passed 180° at the full moon of 23 Dec, so the Moon is waning: Krishna paksha.

The night of Sun 1 Jan ran from sunset 19:51 Sun to sunrise 06:42, 10 h 51 m. Cut into 15 muhurtas of 43 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:42 to 19:51, 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, 19:51 to 06:42 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′. Swati spans 186°40′–200°00′; the Moon entered its pada 2 at 190°. It leaves at 22:19, for Vishakha.

Add the Sun's and the Moon's places among the stars: 258.2° + 192° = 450.2°, one full turn and 90.2°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 80°00′–93°20′ is the 7th, Sukarma. It ends at 12:22, then Dhriti.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Dashami is Vanija and the second Vishti. Vanija runs until 07:17, when the lead reaches 294°; Vishti until 20:00.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:42 to 06:42 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, 7 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 7 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: 17 Mar 1988, 23:02 Thu. Since then the Sun has moved 284.2° round the stars. Vikram Samvat numbers that year 2045; Shaka Samvat numbers it 1910.
