Panchang in Baoding, Hebei, China Mon 16 Apr 2012

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 288°–300° is the 25th, Krishna Dashami. A day takes the tithi in force at its sunrise, 05:40 here. Navami ended at 06:18 Sun, before it. Dashami ends at 06:41, when the lead reaches 300°. The lead passed 180° at the full moon of 7 Apr, so the Moon is waning: Krishna paksha.

The night of Sun 15 Apr ran from sunset 18:55 Sun to sunrise 05:40, 10 h 45 m. Cut into 15 muhurtas of 43 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:40 to 18:56, splits into 8 choghadiyas of 1 h 39 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:56 to 05:38 Tue, splits into 8 choghadiyas of 1 h 20 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 14:57, for Shatabhisha.

Add the Sun's and the Moon's places among the stars: 2.3° + 301.8° = 304.1°. The sum, cut into 27 parts of 13°20′, gives the yoga: 293°20′–306°40′ is the 23rd, Shubha. It ends at 10:15, then Shukla.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Dashami is Vanija and the second Vishti. Vanija ended at 18:25 Sun, when the lead reached 294°; Vishti runs until 06:41.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:40 to 05:38 Tue, so the hours after midnight still belong to Somawara.

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: Meena gives Chaitra. The Sun enters Mesha on 13 Apr, inside the month. The next new moon, 21 Apr, finds it in Mesha and begins Vaishakha.

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 21 Apr, with the Sun in Mesha, begins Vaishakha. Until then this Krishna paksha reads Vaishakha here, and Chaitra in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 22 Mar 2012, 22:37 Thu. Since then the Sun has moved 24° round the stars. Vikram Samvat numbers that year 2069; Shaka Samvat numbers it 1934.
