Panchang in Ipameri, Goiás, Brazil Thu 27 Jun 1912

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 05:46 Wed, before it. Trayodashi ends at 07:03, when the lead reaches 156°. The lead passed 0° at the new moon of 15 Jun, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise. Trayodashi began at 05:46 Wed, before sunrise at 06:43 Wed, and ends at 07:03, after the next sunrise at 06:43. Both days read Trayodashi: it is a vriddhi tithi here.

The night of Wed 26 Jun ran from sunset 17:47 Wed to sunrise 06:43, 12 h 55 m. Cut into 15 muhurtas of 51 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:43 to 17:47, 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, 17:47 to 06:43 Fri, splits into 8 choghadiyas of 1 h 37 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 1 at 226°40′. It leaves at 05:13 Fri, for Mula.

Add the Sun's and the Moon's places among the stars: 72.7° + 228.5° = 301.2°. The sum, cut into 27 parts of 13°20′, gives the yoga: 293°20′–306°40′ is the 23rd, Shubha. It ends at 16:33, then Shukla.

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 18:22 Wed, when the lead reached 150°; Taitila runs until 07:03.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:43 to 06:43 Fri, so the hours after midnight still belong to Guruwara.

A month normally holds one sankranti, the Sun's entry into a new rashi. From 15 Jun 03:23 Sat to 14 Jul 10:12 Sun the Sun stayed in Mithuna, entering Karka at 15 Jul 10:02 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 15 Jun, with the Sun in Mithuna, began Ashadha (Adhik). This Shukla paksha reads Ashadha (Adhik) in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 18 Mar 1912, 19:08 Mon. Since then the Sun has moved 97.4° round the stars. Vikram Samvat numbers that year 1969; Shaka Samvat numbers it 1834.
