Birthday card number (3)

Ross

I believe the answer is:

age

'birthday card number' is the definition.
(I've seen this in another clue)

This is the entire clue.

(Other definitions for age that I've seen before include "Get older" , "Plenty of time" , "Historical period" , "Period of time" , "Length of life" .)

I've seen this clue in The Washington Post and The Wall Street Journal.
