Panchang in Ipameri, Goiás, Brazil Thu 11 Jun 2037

Shiva’s worship centres on nishitha, the midnight muhurta. Chaturdashi runs from 15:35 on Thu 11 Jun to 15:08 on Fri 12 Jun, so only Thursday night’s nishitha (23:46–00:38 Fri) 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, 06:40 here. Dwadashi ended at 15:26 Wed, before it. Trayodashi ends at 15:35, when the lead reaches 336°. The lead passed 180° at the full moon of 29 May, so the Moon is waning: Krishna paksha.

The night of Wed 10 Jun ran from sunset 17:45 Wed to sunrise 06:40, 12 h 55 m. Cut into 15 muhurtas of 51 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:40 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 06:40 Fri, 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′. Krittika spans 26°40′–40°00′; the Moon entered its pada 1 at 26°40′. It leaves at 04:46 Fri, for Rohini.

Add the Sun's and the Moon's places among the stars: 56.4° + 28° = 84.4°. The sum, cut into 27 parts of 13°20′, gives the yoga: 80°00′–93°20′ is the 7th, Sukarma. It ends at 21:59, then Dhriti.

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 03:35, when the lead reached 330°; Vanija runs until 15:35.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:40 to 06:40 Fri, so the hours after midnight still belong to Guruwara.

A month normally holds one sankranti, the Sun's entry into a new rashi. From 15 May 02:54 Fri to 13 Jun 14:10 Sat the Sun stayed in Vrishabha, entering Mithuna at 15 Jun 00:02 Mon, after the new moon. A month with no sankranti is Adhika Jyeshtha, before Jyeshtha itself.

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 13 Jun, with the Sun in Vrishabha, begins Jyeshtha (Adhik). Until then this Krishna paksha reads Jyeshtha (Adhik) here, and Jyeshtha (Adhik) in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 16 Mar 2037, 20:36 Mon. Since then the Sun has moved 84.1° round the stars. Vikram Samvat numbers that year 2094; Shaka Samvat numbers it 1959.
