There are many special things about May babies, including the day they were born. According to statistics, few people are born in May. Only one May birthdate cracks the top 100 popular birthdays (May 23rd lands in 89th place). In general, fewer babies tend to be born on holidays, as those dates draw fewer scheduled inductions or c-sections—so it makes sense that the days that sometimes coincide with Mother’s Day or Memorial Day see lower birthrates. Babies born in May may be of the sign of Taurus or Gemini. May babies born between May 1st and 21st fall under the Taurus sign (aka the bull), and May babies born after the 21st will be Gemini (symbolized by the twins).
