Panchang in Ipameri, Goiás, Brazil Sat 13 Mar 1920

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, 06:15 here. Ashtami ended at 04:13, before it. Navami ends at 06:33 Sun, when the lead reaches 288°. The lead passed 180° at the full moon of 4 Mar, so the Moon is waning: Krishna paksha.

A day takes the tithi in force at its sunrise. Navami began at 04:13, before sunrise at 06:15, and ends at 06:33 Sun, after the next sunrise at 06:15 Sun. Both days read Navami: it is a vriddhi tithi here.

The night of Fri 12 Mar ran from sunset 18:30 Fri to sunrise 06:15, 11 h 45 m. Cut into 15 muhurtas of 47 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:15 to 18:29, splits into 8 choghadiyas of 1 h 31 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:29 to 06:15 Sun, splits into 8 choghadiyas of 1 h 28 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′. Mula spans 240°00′–253°20′; the Moon entered its pada 3 at 246°40′. It leaves at 19:40, for Purva Ashadha.

Add the Sun's and the Moon's places among the stars: 329.8° + 246.7° = 576.5°, one full turn and 216.5°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 213°20′–226°40′ is the 17th, Vyatipata. It ends at 01:15 Sun, then Variyana.

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 17:26, when the lead reaches 282°; Garaja until 06:33 Sun.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:15 to 06:15 Sun, so the hours after midnight still belong to Shaniwara.

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, 20 Mar, 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 20 Mar, 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: 31 Mar 1919, 18:04 Mon. Since then the Sun has moved 342.4° round the stars. Vikram Samvat numbers that year 1976; Shaka Samvat numbers it 1841.
