Panchang in Thazhecode, Kerala Sat 27 Feb 2016

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 216°–228° is the 19th, Krishna Chaturthi. A day takes the tithi in force at its sunrise, 06:42 here. Tritiya ended at 06:05 Fri, before it. Chaturthi ends at 08:42, when the lead reaches 228°. The lead passed 180° at the full moon of 22 Feb, so the Moon is waning: Krishna paksha.

A day takes the tithi in force at its sunrise. Chaturthi began at 06:05 Fri, before sunrise at 06:42 Fri, and ends at 08:42, after the next sunrise at 06:42. Both days read Chaturthi: it is a vriddhi tithi here.

The night of Fri 26 Feb ran from sunset 18:35 Fri to sunrise 06:42, 12 h 7 m. Cut into 15 muhurtas of 48 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:42 to 18:35, splits into 8 choghadiyas of 1 h 29 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:35 to 06:41 Sun, splits into 8 choghadiyas of 1 h 30 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′. Chitra spans 173°20′–186°40′; the Moon entered its pada 3 at 180°. It leaves at 18:27, for Swati.

Add the Sun's and the Moon's places among the stars: 313.8° + 180.9° = 494.7°, one full turn and 134.7°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 133°20′–146°40′ is the 11th, Vriddhi. It ends at 05:09 Sun, then Dhruva.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Chaturthi is Bava and the second Balava. Bava ended at 19:23 Fri, when the lead reached 222°; Balava runs until 08:42.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:42 to 06:41 Sun, so the hours after midnight still belong to Shaniwara.

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 13 Feb, inside the month. The next new moon, 9 Mar, 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 9 Mar, 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: 20 Mar 2015, 15:06 Fri. Since then the Sun has moved 338.4° round the stars. Vikram Samvat numbers that year 2072; Shaka Samvat numbers it 1937.
