Panchang in Ipameri, Goiás, Brazil Fri 12 May 2056

Shiva’s worship centres on nishitha, the midnight muhurta. Chaturdashi runs from 08:17 on Fri 12 May to 10:44 on Sat 13 May, so only Friday night’s nishitha (23:43–00:34 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, 06:29 here. Dwadashi ended at 05:52 Thu, before it. Trayodashi ends at 08:17, when the lead reaches 336°. The lead passed 180° at the full moon of 29 Apr, so the Moon is waning: Krishna paksha.

A day takes the tithi in force at its sunrise. Trayodashi began at 05:52 Thu, before sunrise at 06:29 Thu, and ends at 08:17, after the next sunrise at 06:29. Both days read Trayodashi: it is a vriddhi tithi here.

The night of Thu 11 May ran from sunset 17:48 Thu to sunrise 06:29, 12 h 41 m. Cut into 15 muhurtas of 50 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:29 to 17:48, splits into 8 choghadiyas of 1 h 24 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 17:48 to 06:30 Sat, splits into 8 choghadiyas of 1 h 35 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′. Ashwini spans 0°00′–13°20′; the Moon entered its pada 1 at 0°. It leaves at 03:32 Sat, for Bharani.

Add the Sun's and the Moon's places among the stars: 27.8° + 2.9° = 30.7°. The sum, cut into 27 parts of 13°20′, gives the yoga: 26°40′–40°00′ is the 3rd, Ayushmana. It ends at 23:54, then Saubhagya.

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 19:04 Thu, when the lead reached 330°; Vanija runs until 08:17.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:29 to 06:30 Sat, so the hours after midnight still belong to Shukrawara.

A month normally holds one sankranti, the Sun's entry into a new rashi. From 14 Apr 20:50 Fri to 14 May 13:06 Sun the Sun stayed in Mesha, entering Vrishabha at 14 May 14:13 Sun, after the new moon. A month with no sankranti is Adhika Vaishakha, before Vaishakha 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 14 May, with the Sun in Mesha, begins Vaishakha (Adhik). Until then this Krishna paksha reads Vaishakha (Adhik) here, and Vaishakha (Adhik) in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 16 Mar 2056, 03:52 Thu. Since then the Sun has moved 56° round the stars. Vikram Samvat numbers that year 2113; Shaka Samvat numbers it 1978.
