Muhurat and times of day
Chandra bala in Vedic astrology

Chandra bala: how the API computes it
Chandra bala rates a day for one person by where the Moon is that day. The API counts the Moon's current sign from the person's birth Moon sign. The Moon in the 1st, 3rd, 6th, 7th, 10th or 11th sign from it is seen as favorable.
The Moon in the other six is not. The Moon changes sign about every two and a half days, so the rating changes often. The answer for one day can be different at sunrise and in the evening. It is the sign-based partner of tara bala, which uses nakshatras (star segments).
The two are meant to be read together. GET /v1/rashi/{sign}/today returns chandra bala as part of the daily reading for a Moon sign. POST /v1/muhurta/{activity} adds it, with tara bala, to each good window as for_you. So you can tell one person whether a window suits them, and why not if it does not.
Chandra bala comes back as data, so write your own words for the screen.

How we check the numbers
Every value here starts from planet positions worked out from NASA JPL planet data (DE440). We test them against NASA JPL Horizons, NASA's planet position service. On 25,571 positions from 1850 to 2149, the Sun and planets agree within 0.001 arc seconds. The Moon agrees within 0.011. On 2,000 random birth charts, the rising sign agrees with Swiss Ephemeris within 0.004 arc seconds. An arc second is 1/3,600 of a degree. A practicing astrologer reviews the rules behind these answers. See how we test.
