This template may have no transclusions, because it is substituted by a tool or script, it is used as part of a short-term or less active Wikipedia process, or for some other reason.
{{Holiday|from=date|until=date}} specify when you are "out of office".
{{Holiday|US=yes}} if you would like to change “holiday” to “vacation”.
