Panchang in Thazhecode, Kerala Thu 31 Aug 2017

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 108°–120° is the 10th, Shukla Dashami. A day takes the tithi in force at its sunrise, 06:16 here. Navami ended at 05:17, before it. Dashami ends at 07:36 Fri, when the lead reaches 120°. The lead passed 0° at the new moon of 22 Aug, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise. Dashami began at 05:17, before sunrise at 06:16, and ends at 07:36 Fri, after the next sunrise at 06:15 Fri. Both days read Dashami: it is a vriddhi tithi here.

The night of Wed 30 Aug ran from sunset 18:37 Wed to sunrise 06:16, 11 h 39 m. Cut into 15 muhurtas of 46 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:16 to 18:36, splits into 8 choghadiyas of 1 h 32 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:36 to 06:15 Fri, splits into 8 choghadiyas of 1 h 27 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′. Mula spans 240°00′–253°20′; the Moon entered its pada 1 at 240°. It leaves at 04:46 Fri, for Purva Ashadha.

Add the Sun's and the Moon's places among the stars: 133.7° + 242.2° = 375.9°, one full turn and 15.9°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 13°20′–26°40′ is the 2nd, Priti. It ends at 02:22 Fri, then Ayushmana.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Dashami is Taitila and the second Garaja. Taitila runs until 18:28, when the lead reaches 114°; Garaja until 07:36 Fri.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:16 to 06:15 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: Simha gives Bhadrapada. The Sun enters Kanya on 17 Sep, inside the month. The next new moon, 20 Sep, finds it in Kanya and begins Ashwina.

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 22 Aug, with the Sun in Simha, began Bhadrapada. This Shukla paksha reads Bhadrapada in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 28 Mar 2017, 08:27 Tue. Since then the Sun has moved 150.2° round the stars. Vikram Samvat numbers that year 2074; Shaka Samvat numbers it 1939.
