According to UK websites, magazines and newspapers, people are the starsign Aries if they birthday is 20th March - 20th April.
Being born on April 20th, this makes me an Aries.
However, according to American websites I’m a Taurus. (April 20th - may 20th)
So what is it different in America then in the UK?
There is typically a few days variation in how different people define the “signs”. This is because the astrological signs have no real basis in astronomy. The times of the year for each sign were defined so long ago that the precession of the Earth (the wobble in its axis of spin) has carried us far from the original definitions. If you were born on April 20, the sun was actually in Aries, but if you had been born even a few days earlier, it would have been in Pisces. That’s according to modern definitions of the constellations, in ancient times there were no precise definitions anyway.
Click on this link, and scroll down about two-fifths of the way down until you see a table. This table tells you which consellation (of 13, not 12) that the foreground Sun is in. The dates are determined by the Sun’s crossing of human-invented boundaries of constellations which are not evenly divided into 12 periods.
Notice how different the dates actually are. Also, the Sun tracks through the constellation of Ophiuchus (butterfly, coffin, serpents, you name it) in late November to mid December. Two thousand plus years tends to change an ancient belief system that’s not based on the laws of precession and other astonomical phenomena. Leap year also affects which actual day(s) the Sun crosses each boundary, hence the confusion on whether someone is an Aries or a Pisces. Actually, April 18th is the actual crossover date (on average), so by “astrological” means, April 20th birtdates are actually “Aries”.
I do not believe in astrology for many reasons, and this is just one of them. As for the difference between the UK and the US, it’s probably culturally based on confusion on what is a definitive date for a crossover, when there actually isn’t a definitive date in the first place.
