How to find the date you turn an age
The date you turn age N is your birthday in the year you were born plus N. The weekday changes from year to year, so the tool works it out for that exact date.
Worked example. Born 15 March 1990, counting from 8 October 2026: you turn 65 on Monday, March 15, 2055, 10,385 days from today. You turned 18 on Saturday, March 15, 2008, which was 6,781 days earlier.
This is the date you reach the age, not a legal or program rule. Eligibility ages for benefits, driving or retirement are set by each program and some count from a different date, so check the rule for what you need.
Frequently asked questions
How do I find the date I turn 65?
Add 65 years to your birth date. Born 15 March 1990 you turn 65 on 15 March 2055. Change the age field to any other age.
Which day of the week will I turn that age?
The result shows the weekday for the exact date.
What about a February 29 birthday?
Pick February 28 or March 1 for years with no February 29. In a leap year the real date is used.
Does this tell me when I qualify for a benefit?
No. It only gives the date you reach an age. Programs set their own rules, so confirm with the program.
