We don't want to alarm you,but theworse thing since Mercury went intoretorgrade and turned your life into thereal life equivalent of Pretty Little Liarshas just happened, and it's all NASA's fault.

Yep, a whopping 80% of you are just about to find out that the star sign you've had your wholeentire life and which has probably informed exactly how you live your life each month(ahem) has actually been somewhatinaccurate.

This is becausethe dates defining horoscopes haven't been updated or reasessed since they were originally calculated by ancient astrological typesa whopping 2000 years ago.

Unfortunately the Earth's rotation doesn't exactly match the 365 day calendar year we use, andover timethe earth's axis has actually moved and as the skies we now see are different, so are a lot of our horoscopes have actually changed.

As if that wasn't quite enough of a bombshell, NASA have added a new star sign - we repeat,A NEW STAR SIGN - called Ophiuchus, so there are now 13 signs in total.

To be fair it's not NASA's fault and supposedly Ophiuchus existed all the time, we just didn't know it as those sneaky ancient astologers decided to pretend it didn't exist purely so their charts would look prettier,with just 12 signs spaced evenly around the sun.

No, we don't really get what is happening here either, but frankly we are way too preoccupied with finding out which sign we should be looking at to work out when and when not to flirt with the fit boy from Accounts to make him ours forever tocare right now.

Here's the updated list of star signs with the corresponding dates:

Capricorn: Jan 20 - Feb 16

Aquarius: Feb 16 – March 11

Pisces: March 11 – April 18

Aries: April 18 – May 13

Taurus: May 13 – June 21

Gemini: June 21 – July 20

Cancer: July 20 – Aug 10

Leo: Aug 10 – Sept 16

Virgo: Sept 16 – Oct 30

Libra: Oct 30 – Nov 23

Scorpio: Nov 23 – Nov 29

Ophiuchus: Nov 29 – Dec 17

Sagittarius: Dec 17 – Jan 20

If you are an Ophiuchus, you are apparently probably wise, rebellious and likely to fight for justice. So basically you are Harry Potter, which we suppose issomething at least.

Hands up if you feel like everything you've ever known was a lie? Yeah, us too.
