Panchang in Ipameri, Goiás, Brazil Sun 30 May 2021

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 228°–240° is the 20th, Krishna Panchami. A day takes the tithi in force at its sunrise, 06:35 here. Chaturthi ended at 19:33 Sat, before it. Panchami ends at 17:42, when the lead reaches 240°. The lead passed 180° at the full moon of 26 May, so the Moon is waning: Krishna paksha.

The night of Sat 29 May ran from sunset 17:44 Sat to sunrise 06:35, 12 h 51 m. Cut into 15 muhurtas of 51 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:35 to 17:44, 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, 17:44 to 06:36 Mon, 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′. Uttara Ashadha spans 266°40′–280°00′; the Moon entered its pada 4 at 276°40′. It leaves at 08:11, for Shravana.

Add the Sun's and the Moon's places among the stars: 45° + 279.1° = 324.1°. The sum, cut into 27 parts of 13°20′, gives the yoga: 320°00′–333°20′ is the 25th, Brahma. It ends at 21:33, then Indra.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Panchami is Kaulava and the second Taitila. Kaulava ended at 06:33, when the lead reached 234°; Taitila runs until 17:42.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:35 to 06:36 Mon, so the hours after midnight still belong to Raviwara.

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: Mesha gives Vaishakha. The Sun enters Vrishabha on 14 May, inside the month. The next new moon, 10 Jun, finds it in Vrishabha and begins Jyeshtha.

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 10 Jun, with the Sun in Vrishabha, begins Jyeshtha. Until then this Krishna paksha reads Jyeshtha here, and Vaishakha in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 11 Apr 2021, 23:30 Sun. Since then the Sun has moved 46.7° round the stars. Vikram Samvat numbers that year 2078; Shaka Samvat numbers it 1943.
