Are those constellations accurate?

If you only refer to the 12 constellation, it's almost the same ... otherwise, you can look at the analysis yourself. If you mean the complete constellation, including location, time and so on, it is accurate, because the constellation is not only the sun constellation (that is, the 12 constellation according to the date of birth), but also the rising constellation, the moon constellation and so on ... all of them are very accurate. Read your analysis yourself if you don't believe me.
