What is a half birthday?
A half birthday is the day that falls exactly six months after your actual birthday — the midpoint between one annual celebration and the next. For someone born in January, the half birthday falls in July. For someone born in August, it lands in February. End-of-month birthdays (like August 31) adjust to the last day of the corresponding month when needed.
Half birthdays are celebrated for many reasons: kids with summer birthdays use them to celebrate during school year, parents mark 6-month baby milestones, and adults use them as midyear reason to celebrate. Learn more about the meaning of half birthdays or see why people celebrate them.
