Denmark
As described in the Constitution of Denmark, ยง eighty one, Denmark has mandatory service for all able men. Normal service is four months, and is normally served by men in the age of eighteen to twenty seven. Some special services will take longer. Danish men will typically receive a letter around the time of their 18th birthday, asking when their current education (if any) ends, and some time later, depending on when, they will receive a notice on when to attend to the draft office to be tested physically and psychologically. However some may be deemed unfit for service and not be required to show up.
Even if a person is deemed fit, or partially fit for service, he may avoid having to serve if he draws a high enough number randomly. Persons who are deemed partly fit for service will however be placed lower than those who are deemed fit for service, and therefore have a very low chance of being drafted. Men deemed fit can be called upon for service until their 50th birthday in case of national crisis, regardless of whether normal conscription has been served. This right is very rarely exercised by Danish authorities.
Conscientious objectors can choose to instead serve six months in a non-military position, for example in Redningsberedskabet (dealing with non-military disasters like fires, flood, pollution, etc.) or foreign aid work in a third world country.
