Panchang in Ipameri, Goiás, Brazil Sun 29 Jan 2017

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 12°–24° is the 2nd, Shukla Dwitiya. A day takes the tithi in force at its sunrise, 06:58 here. Pratipada ended at 22:14 Sat, before it. Dwitiya ends at 21:55, when the lead reaches 24°. The lead passed 0° at the new moon of 27 Jan, so the Moon is waxing: Shukla paksha.

The night of Sat 28 Jan ran from sunset 19:53 Sat to sunrise 06:58, 11 h 5 m. Cut into 15 muhurtas of 44 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:58 to 19:53, 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 night here, 19:53 to 06:59 Mon, 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 fixed stars divide the Moon's path into 27 nakshatras of 13°20′, each in 4 padas of 3°20′. Dhanishtha spans 293°20′–306°40′; the Moon entered its pada 3 at 300°. It leaves at 15:33, for Shatabhisha.

Add the Sun's and the Moon's places among the stars: 285.6° + 302° = 587.6°, one full turn and 227.6°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 226°40′–240°00′ is the 18th, Variyana. It ends at 04:00 Mon, then Parigha.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Dwitiya is Balava and the second Kaulava. Balava runs until 10:07, when the lead reaches 18°; Kaulava until 21:55.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:58 to 06:59 Mon, so the hours after midnight still belong to Raviwara.

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: Makara gives Magha. The Sun enters Kumbha on 12 Feb, inside the month. The next new moon, 26 Feb, finds it in Kumbha and begins Phalguna.

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 27 Jan, with the Sun in Makara, began Magha. This Shukla paksha reads Magha in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 7 Apr 2016, 08:23 Thu. Since then the Sun has moved 291.6° round the stars. Vikram Samvat numbers that year 2073; Shaka Samvat numbers it 1938.
