What is a Birthday Calculator?

A birthday calculator is a tool that determines your next birthday date, calculates your age at that birthday, and shows how much time remains until your next birthday celebration.

How it Works

The birthday calculator takes your birth date and calculates when your next birthday will occur. It then determines your age at that birthday and breaks down the time remaining into months, days, weeks, and total days.

  • Total days until next birthday
