@Dennisch posted information about the correct zodiac signs a veeeery long time ago.
Well, sort of.
The zodiac signs are just the constellations which lie on the plane that the Earth orbits the sun on. The current sign is more or less whichever constellation the sun happens to be crossing. But when the zodiac calendar was created 3000 years ago, the Babylonians decided to ignore Ophiuchus and use 12 signs instead, with equal durations, for convenience.

Which reminds me of a similar fact:
When you hear of a "Pink Supermoon" or "Super Flower Blood Moon", it sounds a lot more mysterious or exciting than it actually is.
Words like "Pink" or "Flower" describe the time of year that a particular full moon appears. In modern times we tend to use the list written in the Farmer's Almanac, which assigns a name for each calendar month. But these names were based on recorded names for the full moon as given by various native american tribes, whose calendars were based more closely on the solstices and seasons, so they often don't line up with our modern usage.
A supermoon is simply a time when the moon comes closest to Earth in its elliptical orbit. There's no precise definition because the full moon never happens
precisely at perigee, but when it's particularly close we generally call it a supermoon. At most the moon may appear 14% bigger than it does when farthest from Earth.
A blood moon is caused by a lunar eclipse. When the moon is on the opposite side of Earth from the Sun, light from the Sun refracts through Earth's atmosphere, casting a reddish shadow. From the moon's perspective it's almost as if viewing a sunset through the Earth's sky.
Finally, a blue moon is a case where a full moon appears 13 times in a year, instead of the usual twelve. In modern terms, any time a full moon happens twice in a calendar month, we call it a blue moon, but the traditional definition is more complex: In each of the four seasons based on the solstices and equinoxes, there are normally three full moons per season. Whenever there are four, the third is considered a blue moon.
Hence, according to modern rules, there will be no blue moon this year. But using the traditional rules, this summer (in the Northern hemisphere) goes from June 20 to September 22. There will be four full moons in that period, and the third one, on August 22, would be considered a blue moon (a "seasonal blue moon").
