Panchang in Ipameri, Goiás, Brazil Wed 28 May 2064

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, 06:35 here. Dwadashi ended at 15:51 Tue, before it. Trayodashi ends at 12:55, when the lead reaches 156°. The lead passed 0° at the new moon of 16 May, so the Moon is waxing: Shukla paksha.

The night of Tue 27 May ran from sunset 17:45 Tue to sunrise 06:35, 12 h 50 m. Cut into 15 muhurtas of 51 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:35 to 17:44, 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, 17:44 to 06:35 Thu, 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′. Swati spans 186°40′–200°00′; the Moon entered its pada 3 at 193°20′. It leaves at 13:58, for Vishakha.

Add the Sun's and the Moon's places among the stars: 43.1° + 195.5° = 238.6°. The sum, cut into 27 parts of 13°20′, gives the yoga: 226°40′–240°00′ is the 18th, Variyana. It ends at 08:43, 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 02:23, when the lead reached 150°; Taitila runs until 12:55.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:35 to 06:35 Thu, so the hours after midnight still belong to Budhawara.

A month normally holds one sankranti, the Sun's entry into a new rashi. From 16 May 06:55 Fri to 14 Jun 19:21 Sat the Sun stayed in Vrishabha, entering Mithuna at 14 Jun 22:06 Sat, after the new moon. A month with no sankranti is Adhika Jyeshtha, before Jyeshtha 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 16 May, with the Sun in Vrishabha, began Jyeshtha (Adhik). This Shukla paksha reads Jyeshtha (Adhik) in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 17 Mar 2064, 22:45 Mon. Since then the Sun has moved 69.6° round the stars. Vikram Samvat numbers that year 2121; Shaka Samvat numbers it 1986.
