Panchang in Ipameri, Goiás, Brazil Fri 5 Jun 2043

Shiva’s worship centres on nishitha, the midnight muhurta. Chaturdashi runs from 14:59 on Fri 5 Jun to 11:18 on Sat 6 Jun, so only Friday night’s nishitha (23:45–00:37 Sat) falls within it. No text giving Masik Shivratri’s time was found; nishitha is Tithika’s convention.

Masik Shivratri: every date in Ipameri

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 324°–336° is the 28th, Krishna Trayodashi. A day takes the tithi in force at its sunrise, 06:37 here. Dwadashi ended at 18:29 Thu, before it. Trayodashi ends at 14:59, when the lead reaches 336°. The lead passed 180° at the full moon of 23 May, so the Moon is waning: Krishna paksha.

The night of Thu 4 Jun ran from sunset 17:44 Thu to sunrise 06:37, 12 h 53 m. Cut into 15 muhurtas of 51 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:37 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 06:38 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′. Bharani spans 13°20′–26°40′; the Moon entered its pada 3 at 20°. It leaves at 15:13, for Krittika.

Add the Sun's and the Moon's places among the stars: 50.2° + 21.3° = 71.5°. The sum, cut into 27 parts of 13°20′, gives the yoga: 66°40′–80°00′ is the 6th, Atiganda. It ends at 19:24, then Sukarma.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Trayodashi is Garaja and the second Vanija. Garaja ended at 04:46, when the lead reached 330°; Vanija runs until 14:59.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:37 to 06:38 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: Mesha gives Vaishakha. The Sun enters Vrishabha on 15 May, inside the month. The next new moon, 7 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 7 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: 9 Apr 2043, 16:06 Thu. Since then the Sun has moved 54.8° round the stars. Vikram Samvat numbers that year 2100; Shaka Samvat numbers it 1965.
