John ye sone of br: John Plympton was baptised ye 23'd 4'm 1650. [23 June 1650]
↑ 4.04.1 Since the birth and baptism are both in June, a year apart, one is tempted to think one or the other is off by a year. But they are not strictly inconsistent, and it is possible that the parents waited until John was a year old to baptize him. Therefore, since it would be arbitrary to assume one was right, one was wrong, without pretty good evidence, it seems best to take them at face value.
