The Formula

Age = Current year − Birth year

Then adjust by one depending on your birthday:

• Birthday has passed this year: age = current year − birth year
• Birthday has not passed yet this year: age = current year − birth year − 1

Example — born in 1990:

• 2026 − 1990 = 36
• If your birthday is in January, February, March, or April and it has passed (today is April 25), you are 36.
• If your birthday is in May or later, you are still 35 — you won’t complete 36 years until your birthday arrives.

Why the Birthday Matters

Age is counted in completed years. You don’t turn 36 until you’ve actually lived 36 full years—meaning the anniversary of your birth this calendar year must have passed.

This is why two people born in the same year can legitimately give different answers to “how old are you?” for most of the year. Born January 1, 1990 vs. December 31, 1990: from January 2 to December 30, 2026, one is 36 and the other is still 35.

If you’re approaching one of these ages this year, knowing your exact birthday countdown can help with planning—especially for Social Security and Medicare, where the month of your birthday affects your enrollment windows.
