Help me find minimum and maximum date of births for certain time period?

This may be dumb but I cannot figure this out for the life of me

What are the minimum and maximum date of births if I'm looking for 14 year olds only during the time period of 1/1/17 - 12/31/17? In other words, a person has to be 14 at some point during that date range, not 13 and not 15.

Thanks!
