There is no entitlement to parental leave in respect of children born before 3 June 1996.
The Parental Leave Act, 1998, which came into operation on 3 December 1998 transposes the EU Directive on Parental Leave (96/34/EC) into Irish law. The Act applies only to parents of children born on or after 3 June 1996 or adopted on or after that date. The leave must be taken before the child is five years, subject to a certain modification in the case of an adopted child.
The directive sets down parameters for parental leave but it left much to the discretion of member states.
