Panchang in Pāthardi, Maharashtra Sat 27 Nov 1993

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, 06:43 here. Dwadashi ended at 06:15 Fri, before it. Trayodashi ends at 08:32, when the lead reaches 156°. The lead passed 0° at the new moon of 14 Nov, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise. Trayodashi began at 06:15 Fri, before sunrise at 06:43 Fri, and ends at 08:32, after the next sunrise at 06:43. Both days read Trayodashi: it is a vriddhi tithi here.

The night of Fri 26 Nov ran from sunset 17:49 Fri to sunrise 06:43, 12 h 54 m. Cut into 15 muhurtas of 51 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:43 to 17:49, splits into 8 choghadiyas of 1 h 23 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 17:49 to 06:44 Sun, splits into 8 choghadiyas of 1 h 36 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′. Bharani spans 13°20′–26°40′; the Moon entered its pada 1 at 13°20′. It leaves at 03:31 Sun, for Krittika.

Add the Sun's and the Moon's places among the stars: 221° + 16.2° = 237.2°. The sum, cut into 27 parts of 13°20′, gives the yoga: 226°40′–240°00′ is the 18th, Variyana. It ends at 11:49, then Parigha.

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 19:26 Fri, when the lead reached 150°; Taitila runs until 08:32.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:43 to 06:44 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: Tula gives Kartika. The Sun enters Vrishchika on 16 Nov, inside the month. The next new moon, 13 Dec, finds it in Vrishchika and begins Margashirsha.

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 Nov, with the Sun in Tula, began Kartika. This Shukla paksha reads Kartika in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 23 Mar 1993, 12:44 Tue. Since then the Sun has moved 242.1° round the stars. Vikram Samvat numbers that year 2050; Shaka Samvat numbers it 1915.
