Panchang in Thazhecode, Kerala Sat 13 Oct 2018

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 48°–60° is the 5th, Shukla Panchami. A day takes the tithi in force at its sunrise, 06:15 here. Chaturthi ended at 05:34, before it. Panchami ends at 06:28 Sun, when the lead reaches 60°. The lead passed 0° at the new moon of 9 Oct, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise. Panchami began at 05:34, before sunrise at 06:15, and ends at 06:28 Sun, after the next sunrise at 06:15 Sun. Both days read Panchami: it is a vriddhi tithi here.

The night of Fri 12 Oct ran from sunset 18:09 Fri to sunrise 06:15, 12 h 6 m. Cut into 15 muhurtas of 48 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:15 to 18:09, 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, 18:09 to 06:15 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′. Anuradha spans 213°20′–226°40′; the Moon entered its pada 4 at 223°20′. It leaves at 11:34, for Jyeshtha.

Add the Sun's and the Moon's places among the stars: 175.5° + 223.8° = 399.3°, one full turn and 39.3°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 26°40′–40°00′ is the 3rd, Ayushmana. It ends at 07:21, then Saubhagya.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Panchami is Bava and the second Balava. Bava runs until 17:55, when the lead reaches 54°; Balava until 06:28 Sun.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:15 to 06:15 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: Kanya gives Ashwina. The Sun enters Tula on 17 Oct, inside the month. The next new moon, 7 Nov, finds it in Tula and begins Kartika.

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 Oct, with the Sun in Kanya, began Ashwina. This Shukla paksha reads Ashwina in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 17 Mar 2018, 18:41 Sat. Since then the Sun has moved 202.7° round the stars. Vikram Samvat numbers that year 2075; Shaka Samvat numbers it 1940.
