Panchang in Myjava, Trenčín Region, Slovakia Mon 19 Jun 1978

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, 03:45 here. Dwadashi ended at 07:41 Sun, before it. Trayodashi ends at 04:43, when the lead reaches 156°. The lead passed 0° at the new moon of 5 Jun, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise. Chaturdashi began at 04:43 and ended at 01:16 Tue, between the sunrises of 03:45 and 03:45 Tue. Monday reads Trayodashi and Tuesday reads Purnima: Chaturdashi is a kshaya tithi here.

The night of Sun 18 Jun ran from sunset 19:55 Sun to sunrise 03:45, 7 h 50 m. Cut into 15 muhurtas of 31 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 03:45 to 19:55, splits into 8 choghadiyas of 2 h 1 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 19:55 to 03:45 Tue, splits into 8 choghadiyas of 58 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′. Anuradha spans 213°20′–226°40′; the Moon entered its pada 2 at 216°40′. It leaves at 15:31, for Jyeshtha.

Add the Sun's and the Moon's places among the stars: 63.9° + 219.4° = 283.3°. The sum, cut into 27 parts of 13°20′, gives the yoga: 280°00′–293°20′ is the 22nd, Sadhya. It ends at 18:56, then Shubha.

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 18:16 Sun, when the lead reached 150°; Taitila runs until 04:43.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 03:45 to 03:45 Tue, so the hours after midnight still belong to Somawara.

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: Vrishabha gives Jyeshtha. The Sun enters Mithuna on 15 Jun, inside the month. The next new moon, 5 Jul, finds it in Mithuna and begins Ashadha.

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 5 Jun, with the Sun in Vrishabha, began Jyeshtha. This Shukla paksha reads Jyeshtha in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 7 Apr 1978, 16:15 Fri. Since then the Sun has moved 70° round the stars. Vikram Samvat numbers that year 2035; Shaka Samvat numbers it 1900.
