Panchang in Ipameri, Goiás, Brazil Mon 13 Mar 1916

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 96°–108° is the 9th, Shukla Navami. A day takes the tithi in force at its sunrise, 06:15 here. Ashtami ended at 04:49 Sun, before it. Navami ends at 07:26, when the lead reaches 108°. The lead passed 0° at the new moon of 4 Mar, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise. Navami began at 04:49 Sun, before sunrise at 06:14 Sun, and ends at 07:26, after the next sunrise at 06:15. Both days read Navami: it is a vriddhi tithi here.

The night of Sun 12 Mar ran from sunset 18:30 Sun 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 Tue, 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′. Ardra spans 66°40′–80°00′; the Moon entered its pada 4 at 76°40′. It leaves at 11:49, for Punarvasu.

Add the Sun's and the Moon's places among the stars: 329.8° + 77.3° = 407.1°, one full turn and 47.1°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 40°00′–53°20′ is the 4th, Saubhagya. It ends at 18:01, then Shobhana.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Navami is Balava and the second Kaulava. Balava ended at 18:07 Sun, when the lead reached 102°; Kaulava runs until 07:26.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:15 to 06:15 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: Kumbha gives Phalguna. The Sun enters Meena on 13 Mar, inside the month. The next new moon, 2 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 4 Mar, with the Sun in Kumbha, began Phalguna. This Shukla paksha reads Phalguna in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 15 Mar 1915, 16:41 Mon. Since then the Sun has moved 358.3° round the stars. Vikram Samvat numbers that year 1972; Shaka Samvat numbers it 1837.
