Panchang in Ipameri, Goiás, Brazil Fri 25 May 2012

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 48°–60° is the 5th, Shukla Panchami. A day takes the tithi in force at its sunrise, 06:34 here. Chaturthi ended at 04:45, before it. Panchami ends at 05:40 Sat, when the lead reaches 60°. The lead passed 0° at the new moon of 20 May, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise.

The night of Thu 24 May ran from sunset 17:45 Thu to sunrise 06:34, 12 h 49 m. Cut into 15 muhurtas of 51 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:34 to 17:45, splits into 8 choghadiyas of 1 h 23 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 17:45 to 06:34 Sat, splits into 8 choghadiyas of 1 h 36 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′. Punarvasu spans 80°00′–93°20′; the Moon entered its pada 3 at 86°40′. It leaves at 14:08, for Pushya.

Add the Sun's and the Moon's places among the stars: 40.5° + 89.4° = 129.9°. The sum, cut into 27 parts of 13°20′, gives the yoga: 120°00′–133°20′ is the 10th, Ganda. It ends at 12:37, then Vriddhi.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Panchami is Bava and the second Balava. Bava runs until 17:17, when the lead reaches 54°; Balava until 05:40 Sat.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:34 to 06:34 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: Vrishabha gives Jyeshtha. The Sun enters Mithuna on 14 Jun, inside the month. The next new moon, 19 Jun, finds it in Mithuna and begins Ashadha.

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 May, with the Sun in Vrishabha, began Jyeshtha. This Shukla paksha reads Jyeshtha in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 22 Mar 2012, 11:37 Thu. Since then the Sun has moved 62.2° round the stars. Vikram Samvat numbers that year 2069; Shaka Samvat numbers it 1934.
