The upper and lower limits of an age class are determined by your year of birth, not day of birth; therefore, a junior lifter can lift as a junior until the end of his/her 23rd calendar year. Similarly, a master 1 lifter would become eligible for the masters class in the year in which you will turn 40, and could therefore lift as a master while not having had their 40th birthday yet.
