Panchang in Baoding, Hebei, China Mon 14 Mar 2011

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 96°–108° is the 9th, Shukla Navami. A day takes the tithi in force at its sunrise, 06:32 here. Ashtami ended at 19:49 Sun, before it. Navami ends at 19:22, when the lead reaches 108°. The lead passed 0° at the new moon of 5 Mar, so the Moon is waxing: Shukla paksha.

The night of Sun 13 Mar ran from sunset 18:22 Sun to sunrise 06:32, 12 h 10 m. Cut into 15 muhurtas of 48 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:32 to 18:23, splits into 8 choghadiyas of 1 h 28 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:23 to 06:30 Tue, 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′. Ardra spans 66°40′–80°00′; the Moon entered its pada 2 at 70°. It leaves at 23:47, for Punarvasu.

Add the Sun's and the Moon's places among the stars: 329° + 70.4° = 399.4°, one full turn and 39.4°. 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 07:36, then Saubhagya.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Navami is Balava and the second Kaulava. Balava runs until 07:42, when the lead reaches 102°; Kaulava until 19:22.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:32 to 06:30 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: Kumbha gives Phalguna. The Sun enters Meena on 15 Mar, inside the month. The next new moon, 3 Apr, finds it in Meena and begins Chaitra.

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 5 Mar, with the Sun in Kumbha, began Phalguna. This Shukla paksha reads Phalguna in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 16 Mar 2010, 05:01 Tue. Since then the Sun has moved 357.8° round the stars. Vikram Samvat numbers that year 2067; Shaka Samvat numbers it 1932.
