Several computer programmes need to know whether a particular date is a public holiday for the purposes of managing procedures under the ZUP (and other matters). To my knowledge, the Republic of Slovenia does not have an official publicly accessible web service that would allow such queries. Information on public holidays is available in a non-standardised format (this year) at http://www.vlada.si/o_sloveniji/politicni_sistem/prazniki/. An example of the web service we would like to have, but which is not official, can be found at https://www.s5tech.net/viewtopic.php?f=47&t=6977.
