Panchang in Ipameri, Goiás, Brazil Thu 16 Feb 2017

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 240°–252° is the 21st, Krishna Shashthi. A day takes the tithi in force at its sunrise, 07:07 here. Panchami ended at 23:53 Wed, before it. Shashthi ends at 01:55 Fri, when the lead reaches 252°. The lead passed 180° at the full moon of 10 Feb, so the Moon is waning: Krishna paksha.

The night of Wed 15 Feb ran from sunset 19:46 Wed to sunrise 07:07, 11 h 21 m. Cut into 15 muhurtas of 45 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 07:07 to 19:45, splits into 8 choghadiyas of 1 h 34 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 19:45 to 07:07 Fri, splits into 8 choghadiyas of 1 h 25 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 1 at 186°40′. It leaves at 08:47 Fri, for Vishakha.

Add the Sun's and the Moon's places among the stars: 303.8° + 187.1° = 490.9°, one full turn and 130.9°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 120°00′–133°20′ is the 10th, Ganda. It ends at 11:31, then Vriddhi.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Shashthi is Garaja and the second Vanija. Garaja runs until 12:51, when the lead reaches 246°; Vanija until 01:55 Fri.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 07:07 to 07:07 Fri, so the hours after midnight still belong to Guruwara.

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 26 Feb, with the Sun in Kumbha, begins Phalguna. Until then this Krishna paksha reads Phalguna here, and Magha in the amanta count.

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 309.8° round the stars. Vikram Samvat numbers that year 2073; Shaka Samvat numbers it 1938.
