 However, medieval calendars were still displayed in the Roman fashion with twelve columns from January to December.Beginning in the 16th century, European countries began officially making January 1 the start of the New Year once again—sometimes called "Circumcision Style" because this was the date of the Feast of the Circumcision, being the seventh day after December 25.Historical names for January include its original Roman designation, Ianuarius, the Saxon term "Wulf-monath" (meaning "wolf month") and Charlemagne's designation Wintarmanoth ("winter / cold month").
