Panchang in Ipameri, Goiás, Brazil Fri 20 Mar 2009

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, 06:16 here. Ashtami ended at 04:04 Thu, before it. Navami ends at 06:41, when the lead reaches 288°. The lead passed 180° at the full moon of 10 Mar, so the Moon is waning: Krishna paksha.

A day takes the tithi in force at its sunrise. Navami began at 04:04 Thu, before sunrise at 06:16 Thu, and ends at 06:41, after the next sunrise at 06:16. Both days read Navami: it is a vriddhi tithi here.

The night of Thu 19 Mar ran from sunset 18:24 Thu to sunrise 06:16, 11 h 52 m. Cut into 15 muhurtas of 47 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:16 to 18:23, 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 night here, 18:23 to 06:16 Sat, 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 fixed stars divide the Moon's path into 27 nakshatras of 13°20′, each in 4 padas of 3°20′. Purva Ashadha spans 253°20′–266°40′; the Moon entered its pada 4 at 263°20′. It leaves at 12:15, for Uttara Ashadha.

Add the Sun's and the Moon's places among the stars: 335.9° + 263.7° = 599.6°, one full turn and 239.6°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 226°40′–240°00′ is the 18th, Variyana. It ends at 06:58, then Parigha.

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 ended at 17:23 Thu, when the lead reached 282°; Garaja runs until 06:41.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:16 to 06:16 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 14 Mar, inside the month. The next new moon, 26 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 26 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: 6 Apr 2008, 00:55 Sun. Since then the Sun has moved 343.1° round the stars. Vikram Samvat numbers that year 2065; Shaka Samvat numbers it 1930.
