Panchang in Ipameri, Goiás, Brazil Sat 12 Jul 1969

Shiva’s worship centres on nishitha, the midnight muhurta. Chaturdashi runs from 06:23 on Sat 12 Jul to 08:46 on Sun 13 Jul, so only Saturday night’s nishitha (23:52–00:44 Sun) 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: 336°–348° is the 29th, Krishna Chaturdashi. A day takes the tithi in force at its sunrise, 06:44 here. Trayodashi ended at 06:23, before it. Chaturdashi ends at 08:46 Sun, when the lead reaches 348°. The lead passed 180° at the full moon of 29 Jun, so the Moon is waning: Krishna paksha.

A day takes the tithi in force at its sunrise. Chaturdashi began at 06:23, before sunrise at 06:44, and ends at 08:46 Sun, after the next sunrise at 06:44 Sun. Both days read Chaturdashi: it is a vriddhi tithi here.

The night of Fri 11 Jul ran from sunset 17:52 Fri to sunrise 06:44, 12 h 52 m. Cut into 15 muhurtas of 51 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:44 to 17:52, 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, 17:52 to 06:44 Sun, 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′. Mrigashira spans 53°20′–66°40′; the Moon entered its pada 3 at 60°. It leaves at 14:59, for Ardra.

Add the Sun's and the Moon's places among the stars: 86.4° + 62.6° = 149°. The sum, cut into 27 parts of 13°20′, gives the yoga: 146°40′–160°00′ is the 12th, Dhruva. It ends at 03:18 Sun, then Vyaghata.

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 19:34, when the lead reaches 342°; Shakuni until 08:46 Sun.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:44 to 06:44 Sun, so the hours after midnight still belong to Shaniwara.

A month normally holds one sankranti, the Sun's entry into a new rashi. From 14 Jun 20:08 Sat to 14 Jul 11:11 Mon the Sun stayed in Mithuna, entering Karka at 16 Jul 00:40 Wed, after the new moon. A month with no sankranti is Adhika Ashadha, before Ashadha 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 Jul, with the Sun in Mithuna, begins Ashadha (Adhik). Until then this Krishna paksha reads Ashadha (Adhik) here, and Ashadha (Adhik) in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 18 Mar 1969, 01:51 Tue. Since then the Sun has moved 112.4° round the stars. Vikram Samvat numbers that year 2026; Shaka Samvat numbers it 1891.
