Panchang in Myjava, Trenčín Region, Slovakia Sat 13 May 1995

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 144°–156° is the 13th, Shukla Trayodashi. A day takes the tithi in force at its sunrise, 05:11 here. Dwadashi ended at 08:12 Fri, before it. Trayodashi ends at 05:30, when the lead reaches 156°. The lead passed 0° at the new moon of 29 Apr, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise. Chaturdashi began at 05:30 and ended at 02:19 Sun, between the sunrises of 05:11 and 05:10 Sun. Saturday reads Trayodashi and Sunday reads Purnima: Chaturdashi is a kshaya tithi here.

The night of Fri 12 May ran from sunset 20:19 Fri to sunrise 05:11, 8 h 52 m. Cut into 15 muhurtas of 35 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:11 to 20:21, splits into 8 choghadiyas of 1 h 53 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 20:21 to 05:10 Sun, splits into 8 choghadiyas of 1 h 6 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′. Chitra spans 173°20′–186°40′; the Moon entered its pada 4 at 183°20′. It leaves at 09:38, for Swati.

Add the Sun's and the Moon's places among the stars: 28.1° + 183.9° = 212°. The sum, cut into 27 parts of 13°20′, gives the yoga: 200°00′–213°20′ is the 16th, Siddhi. It ends at 07:08, then Vyatipata.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Trayodashi is Kaulava and the second Taitila. Kaulava ended at 18:55 Fri, when the lead reached 150°; Taitila runs until 05:30.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:11 to 05:10 Sun, so the hours after midnight still belong to Shaniwara.

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: Mesha gives Vaishakha. The Sun enters Vrishabha on 15 May, inside the month. The next new moon, 29 May, finds it in Vrishabha and begins Jyeshtha.

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 29 Apr, with the Sun in Mesha, began Vaishakha. This Shukla paksha reads Vaishakha in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 31 Mar 1995, 04:08 Fri. Since then the Sun has moved 42° round the stars. Vikram Samvat numbers that year 2052; Shaka Samvat numbers it 1917.
