Is an employee entitled to an additional day of leave if a holiday falls during the employee's family and medical leave?

No. The fact that a holiday may occur within the week taken as family and medical leave has no effect; the week is counted as a week of family and medical leave. However, if employees generally are not expected to report for work for one or more weeks (e.g., winter holiday closure), the days of the closure do not count against the employee's entitlement to family and medical leave.
