This modern country has strong democratic institutions, and leans toward extreme religious conservatism.
The state religion is omnipresent in culture, and has a major influence on the laws passed by government. One way in which this is visible is in the criminal justice system: the state doesn't believe in long prison sentences. It is expensive to maintain in the long term, and considered a waste of resources. Prison is for people who can be rehabilitated, and the maximum time would usually be about 20 years. Serial offenders, or those who have committed heinous crimes, are sentenced to death.
According to religioua tradition, the gods have decreed that The method of execution is always burning at the stake, in which a person is tied to a stake of wood and then immolated. Executions are treated as a ritual, and can only be done at a particular point in time, which is the last month of the year. Any day can be chosen, so long as it is in that timeframe. Executions make no distinctions between the sexes, and are done publicly. In extemely rare cases, even children are subjected to this. The practice is enforced regardless of when the person was sentenced. While culture demands this, most religious traditions are rooted in logical and sensible reasons, such as not eating pork to prevent sickness. This original purpose is long forgotten, but the ritual has remained over the generations. What practical reason would there be for prevent burning at the stake for the rest of the year, except in the last month?
