Panchang in Ipameri, Goiás, Brazil Fri 18 Jan 1985

Shiva’s Pradosh puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi runs from 01:21 on Fri 18 Jan to 00:23 on Sat 19 Jan, so only Friday’s pradosha (18:54–21:06) falls within it. No text giving Pradosh Vrat’s time was found; pradosha is Tithika’s convention.

Shiva’s worship centres on nishitha, the midnight muhurta. Chaturdashi runs from 00:23 on Sat 19 Jan to 23:43 on Sat 19 Jan, so it touches only Friday night’s nishitha (00:01 Sat–00:45 Sat). No text giving Masik Shivratri’s time was found; nishitha is Tithika’s convention.

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, 05:52 here. Dwadashi ended at 01:21, before it. Trayodashi ends at 00:23 Sat, when the lead reaches 336°. The lead passed 180° at the full moon of 6 Jan, so the Moon is waning: Krishna paksha.

The night of Thu 17 Jan ran from sunset 18:54 Thu to sunrise 05:52, 10 h 58 m. Cut into 15 muhurtas of 43 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:52 to 18:54, splits into 8 choghadiyas of 1 h 37 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:54 to 05:52 Sat, splits into 8 choghadiyas of 1 h 22 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′. Mula spans 240°00′–253°20′; the Moon entered its pada 1 at 240°. It leaves at 03:55 Sat, for Purva Ashadha.

Add the Sun's and the Moon's places among the stars: 274.6° + 240.9° = 515.5°, one full turn and 155.5°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 146°40′–160°00′ is the 12th, Dhruva. It ends at 13:16, then Vyaghata.

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 runs until 12:50, when the lead reaches 330°; Vanija until 00:23 Sat.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:52 to 05:52 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: Dhanu gives Pausha. The Sun enters Makara on 13 Jan, inside the month. The next new moon, 20 Jan, finds it in Makara and begins Magha.

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 20 Jan, with the Sun in Makara, begins Magha. Until then this Krishna paksha reads Magha here, and Pausha in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 1 Apr 1984, 09:09 Sun. Since then the Sun has moved 286.3° round the stars. Vikram Samvat numbers that year 2041; Shaka Samvat numbers it 1906.
