Panchang in Ipameri, Goiás, Brazil Tue 12 Mar 1907

Shiva’s worship centres on nishitha, the midnight muhurta. Chaturdashi runs from 06:05 on Tue 12 Mar to 04:21 on Wed 13 Mar, so only Tuesday night’s nishitha (23:52–00:39 Wed) 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, 06:14 here. Trayodashi ended at 06:11, before it. Chaturdashi ends at 04:28 Wed, when the lead reaches 348°. The lead passed 180° at the full moon of 28 Feb, so the Moon is waning: Krishna paksha.

The night of Mon 11 Mar ran from sunset 18:31 Mon to sunrise 06:14, 11 h 43 m. Cut into 15 muhurtas of 46 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:14 to 18:30, splits into 8 choghadiyas of 1 h 32 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:30 to 06:14 Wed, 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 fixed stars divide the Moon's path into 27 nakshatras of 13°20′, each in 4 padas of 3°20′. Dhanishtha spans 293°20′–306°40′; the Moon entered its pada 4 at 303°20′. It leaves at 10:36, for Shatabhisha.

Add the Sun's and the Moon's places among the stars: 328.1° + 304.1° = 632.2°, one full turn and 272.2°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 266°40′–280°00′ is the 21st, Siddha. It ends at 18:43, then Sadhya.

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 17:17, when the lead reaches 342°; Shakuni until 04:28 Wed.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:14 to 06:14 Wed, so the hours after midnight still belong to Mangalawara.

A month normally holds one sankranti, the Sun's entry into a new rashi. From 12 Feb 14:42 Tue to 14 Mar 03:04 Thu the Sun stayed in Kumbha, entering Meena at 14 Mar 03:59 Thu, after the new moon. A month with no sankranti is Adhika Phalguna, before Phalguna 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 Mar, with the Sun in Kumbha, begins Phalguna (Adhik). Until then this Krishna paksha reads Phalguna (Adhik) here, and Phalguna (Adhik) in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 24 Mar 1906, 20:51 Sat. Since then the Sun has moved 347.2° round the stars. Vikram Samvat numbers that year 1963; Shaka Samvat numbers it 1828.
