Name day
From A Wiki of Ice and Fire
A name day is the Westerosi equivalent to a birthday. The day a child is born he/she is also given a name that day so a person's age is recorded with his/her name day as the beginning. The only exception is for free folk births, as they do not name their children until their child reaches the age of two.
