Every male Finnish citizen aged between 18 until 30 is by law liable for military service. The civic duty defined in chapter 1 of the Conscription Act starts at the beginning of the year in which a young man reaches his 18th birthday and continues until the end of the year in which he turns 30. A conscript can ask for postponement because of e.g. studies.
