Panchang in Myjava, Trenčín Region, Slovakia Sun 14 Jan 2018

The Sun enters Makara at 09:16, between sunrise (07:38) and sunset (16:19). The Dharmasindhu’s punya kala is the 40 ghatis after the ingress, so the bath and gifts fall that day: Sun 14 Jan.

Shiva’s Pradosh puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi runs from 19:22 on Sat 13 Jan to 22:01 on Sun 14 Jan, so only Sunday’s pradosha (16:19–19:22) 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 22:01 on Sun 14 Jan to 00:41 on Tue 16 Jan, holding as much of nishitha on both nights. The Nirnayasindhu then takes the earlier: Sun 14 Jan. 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, 07:38 here. Dwadashi ended at 19:22 Sat, before it. Trayodashi ends at 22:01, when the lead reaches 336°. The lead passed 180° at the full moon of 2 Jan, so the Moon is waning: Krishna paksha.

The night of Sat 13 Jan ran from sunset 16:17 Sat to sunrise 07:38, 15 h 21 m. Cut into 15 muhurtas of 1 h 1 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 07:38 to 16:19, splits into 8 choghadiyas of 1 h 5 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 16:19 to 07:37 Mon, splits into 8 choghadiyas of 1 h 54 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′. Jyeshtha spans 226°40′–240°00′; the Moon entered its pada 4 at 236°40′. It leaves at 08:44, for Mula.

Add the Sun's and the Moon's places among the stars: 269.9° + 239.5° = 509.4°, one full turn and 149.4°. 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 03:28 Mon, 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 08:41, when the lead reaches 330°; Vanija until 22:01.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 07:38 to 07:37 Mon, so the hours after midnight still belong to Raviwara.

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 14 Jan, inside the month. The next new moon, 17 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 17 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: 28 Mar 2017, 04:57 Tue. Since then the Sun has moved 286.4° round the stars. Vikram Samvat numbers that year 2074; Shaka Samvat numbers it 1939.
