Misleading. NASA did not update the zodiac to add another astrological sign or adjust the dates.

Is it true that horoscopes change every year?
Is that to say that your zodiac sign changes each year? No, it’s more like once every 30 years or so. (Thank G, you’ve got some time to think about it.) “Each sign has 30 degrees, and the advanced sun moves less than a degree per year, so this shift is really slow,” Montfar explains.
What’s the deal with certain horoscopes having various dates?
The finding was first announced by NASA in a blog post earlier this year, explaining that when the ancient Babylonians developed the zodiac over 3,000 years ago, they wanted dates on the calendar to match to star constellations. However, there were 13 constellations to consider, and they were using a 12-month calendar. As a result, they abandoned Ophiuchus.
NASA also pointed out that the Earth’s axis no longer points in the same direction as it did when the constellations were first drawn, therefore all of our signs now have various date ranges.
To put it another way, astrological turmoil. NASA’s science nerds don’t seem to mind that they’ve turned our lives upside down. “Here at NASA, we study astronomy, not astrology,” they said in a statement last week. We didn’t make any changes to the zodiac signs; we simply did the math.
What is the frequency with which astrology signs change?
“It slews slowly around in a circle every 26,000 years, much like a spinning top wobbling around on a table. On a daily timescale, this additional motion is nearly undetectable, but it mounts up over millennia.” So, while the stars do not move, they appear to move over centuries.
