How Is Age Calculated?

Age is calculated by finding the difference between your date of birth and the current date. While the concept is simple the exact calculation accounts for leap years, varying month lengths, and whether your birthday has occurred yet in the current year.

For example, if you were born on March 15, 1990, and today is July 7, 2026, your exact age is 36 years, 3 months, and 22 days. You have lived approximately 13,264 days or 1,894 weeks.

Why Does Exact Age Matter?

Knowing your exact age matters in many real-world situations. Legal ages for driving, voting, drinking, and retirement benefits are calculated to the exact date. Medical screening guidelines are tied to specific ages. Insurance premiums often change on your birthday. Social Security benefits are based on your exact birth date and the age at which you choose to claim them.

Age and Retirement Planning

Your age is one of the most important factors in retirement planning. The age at which you can access retirement accounts without penalty, claim Social Security benefits, and qualify for Medicare are all tied to specific birthdays.

You can access your 401k and IRA without the 10% early withdrawal penalty starting at age 59 and a half. Required Minimum Distributions from traditional retirement accounts must begin at age 73 under current IRS rules. Social Security benefits can be claimed as early as age 62 at a reduced amount or delayed until age 70 for maximum benefits. Medicare eligibility begins at age 65 for most Americans.
