When will you be the same age your parent is today? Enter your date of birth and your parent's date of birth to find the exact calendar date you reach their current age.
The calculator takes your parent's current age (their integer age on today's date) and adds that number of years to your date of birth. The result is the exact calendar date on which you turn the age your parent is now — either a future date you are working toward, today, or a date in the past if you are older than your parent currently is.
It calculates the exact date on which you will reach (or reached) the age your parent is today. For example, if your parent is 55 right now, the calculator tells you the calendar date on which you will turn 55.
That just means the date you matched their current age is in the past. The calculator handles this and shows the historical date.
Leap-day birthdays only fall on a real February 29 in leap years. In other years the anniversary rolls to March 1, which is the convention used here.
