Panchang in Davinópolis, Maranhão, Brazil Thu 24 May 1984

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, 06:11 here. Ashtami ended at 03:53 Wed, before it. Navami ends at 06:15, when the lead reaches 288°. The lead passed 180° at the full moon of 15 May, so the Moon is waning: Krishna paksha.

A day takes the tithi in force at its sunrise. Navami began at 03:53 Wed, before sunrise at 06:11 Wed, and ends at 06:15, after the next sunrise at 06:11. Both days read Navami: it is a vriddhi tithi here.

The night of Wed 23 May ran from sunset 18:01 Wed to sunrise 06:11, 12 h 10 m. Cut into 15 muhurtas of 48 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:11 to 18:01, 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 night here, 18:01 to 06:11 Fri, 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 fixed stars divide the Moon's path into 27 nakshatras of 13°20′, each in 4 padas of 3°20′. Purva Bhadrapada spans 320°00′–333°20′; the Moon entered its pada 3 at 326°40′. It leaves at 17:32, for Uttara Bhadrapada.

Add the Sun's and the Moon's places among the stars: 39.7° + 327.7° = 367.4°, one full turn and 7.4°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 0°00′–13°20′ is the 1st, Vishkambha. It ends at 17:11, then Priti.

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 17:04 Wed, when the lead reached 282°; Garaja runs until 06:15.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:11 to 06:11 Fri, so the hours after midnight still belong to Guruwara.

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, 30 May, 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 30 May, 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: 1 Apr 1984, 09:09 Sun. Since then the Sun has moved 51.4° round the stars. Vikram Samvat numbers that year 2041; Shaka Samvat numbers it 1906.
