Panchang in Ipameri, Goiás, Brazil Fri 1 Apr 1921

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 276°–288° is the 24th, Krishna Navami. A day takes the tithi in force at its sunrise, 06:18 here. Ashtami ended at 19:23 Thu, before it. Navami ends at 21:50, when the lead reaches 288°. The lead passed 180° at the full moon of 23 Mar, so the Moon is waning: Krishna paksha.

The night of Thu 31 Mar ran from sunset 18:15 Thu to sunrise 06:18, 12 h 3 m. Cut into 15 muhurtas of 48 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:18 to 18:14, splits into 8 choghadiyas of 1 h 29 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:14 to 06:19 Sat, splits into 8 choghadiyas of 1 h 30 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 Ashadha spans 266°40′–280°00′; the Moon entered its pada 1 at 266°40′. It leaves at 03:56 Sat, for Shravana.

Add the Sun's and the Moon's places among the stars: 348.3° + 269.3° = 617.6°, one full turn and 257.6°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 253°20′–266°40′ is the 20th, Shiva. It ends at 23:08, then Siddha.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Navami is Taitila and the second Garaja. Taitila runs until 08:36, when the lead reaches 282°; Garaja until 21:50.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:18 to 06:19 Sat, so the hours after midnight still belong to Shukrawara.

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: Kumbha gives Phalguna. The Sun enters Meena on 13 Mar, inside the month. The next new moon, 8 Apr, finds it in Meena and begins Chaitra.

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 8 Apr, with the Sun in Meena, begins Chaitra. Until then this Krishna paksha reads Chaitra here, and Phalguna 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 371.5° round the stars. Vikram Samvat numbers that year 1977; Shaka Samvat numbers it 1842.
