Dry January is a custom of abstaining from alcohol for the month of January, particularly practised in the United Kingdom. The custom, as a formal entity, appears to be relatively recent, being described as having "sprung up in recent years" even in 2014. Although the Finnish government launched a campaign called "Sober January" already in 1942 as part of its war effort. The term "Dry January" was registered as a trademark by the charity Alcohol Concern in mid-2014; the first ever Dry January campaign by Alcohol Concern occurred in January 2013. In the leadup to the January 2015 campaign, for the first time Alcohol Concern partnered with Public Health England.
