Panchang in Ipameri, Goiás, Brazil Thu 17 May 2018

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 24°–36° is the 3rd, Shukla Tritiya. A day takes the tithi in force at its sunrise, 06:31 here. Dwitiya ended at 02:57, before it. Tritiya ends at 23:54, when the lead reaches 36°. The lead passed 0° at the new moon of 15 May, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise.

The night of Wed 16 May ran from sunset 17:47 Wed to sunrise 06:31, 12 h 44 m. Cut into 15 muhurtas of 50 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:31 to 17:47, splits into 8 choghadiyas of 1 h 24 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 06:31 Fri, splits into 8 choghadiyas of 1 h 35 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′. Mrigashira spans 53°20′–66°40′; the Moon entered its pada 2 at 56°40′. It leaves at 20:03, for Ardra.

Add the Sun's and the Moon's places among the stars: 32.3° + 58.4° = 90.7°. The sum, cut into 27 parts of 13°20′, gives the yoga: 80°00′–93°20′ is the 7th, Sukarma. It ends at 10:33, then Dhriti.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Tritiya is Taitila and the second Garaja. Taitila runs until 13:25, when the lead reaches 30°; Garaja until 23:54.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:31 to 06:31 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 May 08:47 Tue to 13 Jun 16:43 Wed the Sun stayed in Vrishabha, entering Mithuna at 15 Jun 03:06 Fri, 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 15 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 2018, 10:11 Sat. Since then the Sun has moved 59.5° round the stars. Vikram Samvat numbers that year 2075; Shaka Samvat numbers it 1940.
