Your AOW pension age depends on your date of birth. If you were born before 1 January 1959, you can find out your AOW pension age by using the calculation tool on this website. If you were born after 31 December 1958, your AOW pension age will be at least 67. Your definite AOW pension age will be fixed 5 years in advance. We therefore advise you to check your AOW pension age each year in January. Find out your AOW pension age
