The Rarest Signs
1. Aquarius (January 20 - February 18)
Aquarius is often cited as the rarest sign. February has the fewest days, and Aquarius falls during late January and February—historically lower birth months.
2. Capricorn (December 22 - January 19)
Capricorn spans late December and January, another period with historically fewer births.
3. Aries (March 21 - April 19)
Aries babies would be conceived in summer, when birth rates often dip slightly.
The Most Common Signs
1. Virgo (August 23 - September 22)
September consistently has the highest birth rates in the US. Virgo season captures most of these births.
2. Libra (September 23 - October 22)
Libra follows Virgo and catches the late September birth surge.
3. Scorpio (October 23 - November 21)
Fall births remain high, making Scorpio another common sign.
Why the Variation?
- September births peak (conceived around December/holidays)
- January/February births are lowest
- This creates variation in zodiac sign frequency
Does Rarity Matter?
