How to Use the DOB Calculator

A DOB Calculator is a tool that calculates a person’s exact age, determines the date of their next birthday, and shows how many days remain until that birthday.

This type of calculator is widely used in everyday life for both personal and professional purposes—whether you’re planning a celebration, completing official paperwork, or simply curious about your precise age.

Why Use a DOB Calculator?

While most of us know our year of birth, calculating the exact age in years, months, and days can be tricky. The DOB Calculator automates this process, saving time and ensuring accuracy.

It’s helpful for:

• Personal use → To know your exact age and track birthdays.
• Parents → To keep track of children’s ages for school admissions, medical check-ups, or sports eligibility.
• Employers → To verify employee ages for compliance with minimum age requirements.
• Legal purposes → To confirm age-related eligibility, like voting, licenses, or retirement.
