The Mail on Sunday reports that Pagan inmates are given a day off from work for Halloween.

Prison Service bosses have instructed staff to grant the convicts, who include Devil worshippers and Satanists, special privileges on Tuesday.
While fellow prisoners sew mail bags and undertake other jail work, the Pagans will be allowed to celebrate their ‘holiday’.
They can use certain artefacts, including rune stones, flexible twigs and hoodless robes, provided they are kept in their cells or worn during communal worship. Robes with hoods are banned for ‘security reasons’, however.

Obviously they will not be able to wear this Tchibo hoodie (Kapuzinerjacke), then.

The Home Office papers reveal that Pagans can choose a day off work on two dates from eight of their festivals each year.
These include the Spring Equinox on March 20, the Midsummer Solstice on June 21 and Hallowe’en – the Samhain, or Summer’s End, as it was known in Celtic times – on October 31. Christian prisoners are allowed three days off – on Good Friday, Easter Day and Christmas Day.
Muslims are entitled to the most time off – 26 days to pray, including the fast of Ramadan. Buddhists get three days, Hindus ten and Jews seven.
