Panchang in Davinópolis, Maranhão, Brazil Tue 30 Jun 1981

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 336°–348° is the 29th, Krishna Chaturdashi. A day takes the tithi in force at its sunrise, 06:18 here. Trayodashi ended at 22:15 Mon, before it. Chaturdashi ends at 19:03, when the lead reaches 348°. The lead passed 180° at the full moon of 17 Jun, so the Moon is waning: Krishna paksha.

A day takes the tithi in force at its sunrise.

Sunrise here, 05:26, came before Trayodashi ended at 06:45: this day reads Trayodashi. Chaturdashi ends at 03:33 Wed, before the next sunrise, so no day here reads Chaturdashi: it is kshaya.

Sunrise here, 06:18, came after Trayodashi ended at 22:15 Mon: this day reads Chaturdashi.

The night of Mon 29 Jun ran from sunset 18:07 Mon to sunrise 06:18, 12 h 11 m. Cut into 15 muhurtas of 48 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:18 to 18:07, 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, 18:07 to 06:19 Wed, 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′. Mrigashira spans 53°20′–66°40′; the Moon entered its pada 1 at 53°20′. It leaves at 00:22 Wed, for Ardra.

Add the Sun's and the Moon's places among the stars: 74.9° + 55.6° = 130.5°. The sum, cut into 27 parts of 13°20′, gives the yoga: 120°00′–133°20′ is the 10th, Ganda. It ends at 10:42, then Vriddhi.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Chaturdashi is Vishti and the second Shakuni. Vishti runs until 08:38, when the lead reaches 342°; Shakuni until 19:03.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:18 to 06:19 Wed, so the hours after midnight still belong to Mangalawara.

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, 1 Jul, 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 1 Jul, with the Sun in Mithuna, begins Ashadha. Until then this Krishna paksha reads Ashadha here, and Jyeshtha in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 4 Apr 1981, 17:19 Sat. Since then the Sun has moved 83.5° round the stars. Vikram Samvat numbers that year 2038; Shaka Samvat numbers it 1903.
