Actually that simplification doesn’t work - someone born on 1/Mar/2000 should be 11 on 1/Mar/2011 and this answers 10 (the previous version did work).
This does make me think its tricky enough to put this in the core - I may submit it along with the unit tests I borrowed from Stack Overflow (the shame)… Its a good problem though. Thanks for discussing it with me.
