How your age is calculated
Age is your date of birth to the reference date, broken into completed years, whole remaining months, and leftover days.

How is age calculated?
We subtract your birth date from the reference date while accounting for varying month lengths and leap years. Year-month-day breakdown matches the standard civil age used on documents.
Tip: your "completed years" plus months/days is what shows on official forms. Total days/weeks are useful for interest calculations and tenancy agreements.
