How to Find Your New Zodiac Sign After NASA's Recalculations

Not that it actually affects your personality or your future.

The Babylonians were lazy: When they came up with the zodiac signs, they left one out on purpose. Using 12 signs instead of 13 was more convenient because it fit their calendar of 12 lunar cycles per year. But that means everyone who’s adopted their astrological calendar and associated personality profiles in the millennia since have been wrong.

NASA pointed out the error last month and offered up a correction. The new zodiac calendar has some big changes. Not only are there now 13 signs, the dates have changed in some cases. NASA updated the calendar to reflect the actual amount of time the sun spends aligned with each constellation, which has changed since the Babylonian’s time thanks to the Earth’s tilt. Scorpio, for example, only takes up seven days of the year. The new sign, Ophiuchus, takes up 19 days.

For most people, zodiac signs will shift to the sign previous. Many Scorpios are now a Libra, for instance. For a few people, signs won’t change at all; if you were born between March 11 and 20, for example, you’re still a Pisces. You can use this handy tool to find your new sign.

Here’s the new calendar:

Capricorn: January 20 - February 16
Aquarius: February 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 - August 10
Leo: August 10 - September 16
Virgo: September 16 - October 30
Libra: October 30 - November 23
Scorpio: November 23 - 29
Ophiuchus: November 29 - December 17
Sagittarius: December 17 - January 20

NASA, despite their calculations and calendar update, was quick to point out that astrology is, in fact, not a science. Astronomy, on the other hand — the study of stars and space — is a science. Astrologists contend that the slight gravitational pull of the sun and stars can affect personalities depending on the time of year and when people were born. Astronomers see no such personality/stellar correlation.
