Quick answer
Add 40, 50 or 65 to your birth year. Your milestone normally falls on the same month and day as your birthday. For example, someone born on June 15, 1990 turns 40 on June 15, 2030, turns 50 on June 15, 2040 and turns 65 on June 15, 2055.

Why the full birth date matters
The birth year tells you the milestone year, but the month and day determine the exact milestone date and whether that birthday has already occurred.
Planning around milestone ages
- Age 40: often used as a personal or career milestone.
- Age 50: may be relevant to long-term financial, health or family planning.
- Age 65: is commonly associated with retirement planning, but official pension and benefit rules vary by country and programme.
