Panchang in Myjava, Trenčín Region, Slovakia Fri 12 Jul 1912

Shiva’s Pradosh puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi runs from 00:43 on Fri 12 Jul to 21:36 on Fri 12 Jul, so only Friday’s pradosha (19:50–21:28) 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 21:36 on Fri 12 Jul to 18:02 on Sat 13 Jul, so only Friday night’s nishitha (23:38–00:11 Sat) falls within it. 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, 03:58 here. Dwadashi ended at 00:43, before it. Trayodashi ends at 21:36, when the lead reaches 336°. The lead passed 180° at the full moon of 29 Jun, so the Moon is waning: Krishna paksha.

The night of Thu 11 Jul ran from sunset 19:51 Thu to sunrise 03:58, 8 h 7 m. Cut into 15 muhurtas of 32 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 03:58 to 19:50, splits into 8 choghadiyas of 1 h 59 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 19:50 to 03:59 Sat, splits into 8 choghadiyas of 1 h 1 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′. Rohini spans 40°00′–53°20′; the Moon entered its pada 4 at 50°. It leaves at 05:12, for Mrigashira.

Add the Sun's and the Moon's places among the stars: 86.7° + 52.6° = 139.3°. The sum, cut into 27 parts of 13°20′, gives the yoga: 133°20′–146°40′ is the 11th, Vriddhi. It ends at 15:13, then Dhruva.

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 11:14, when the lead reaches 330°; Vanija until 21:36.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 03:58 to 03:59 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 15 Jun 07:23 Sat to 14 Jul 14:12 Sun the Sun stayed in Mithuna, entering Karka at 15 Jul 14:02 Mon, 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 1912, 23:08 Mon. Since then the Sun has moved 111.4° round the stars. Vikram Samvat numbers that year 1969; Shaka Samvat numbers it 1834.
