Why Zodiac Signs Don't Align With Calendar Months
Zodiac sign dates are based on the sun's position along the ecliptic, not on neat calendar boundaries. Because Earth's orbit doesn't divide evenly into twelve 30-day months, each zodiac sign's date range starts partway through one calendar month and ends partway through the next. This is why, for example, people born in early April are Aries while those born later in April are Taurus.

FAQ
Yes. Since sign boundaries fall mid-month, two people born in the same calendar month can easily have different zodiac signs depending on the exact day.
A cusp birthday falls within a day or two of a sign boundary. While you technically belong to one sign or the other, cusp-born people sometimes feel they share traits of both neighboring signs.
