Abstract: In Sweden, the celebration of name-days is still important and the, since a century, very much secular name-day calendar generates much public interest when changes are made. In this paper, the history of name-day celebrations is illustrated, with a focus on its heydays in the 19th century. The diachronic development of the different name-day calendars from the saints’ names in Calendarium Romanum to the radical changes made in 1901 and during the late 20th century is depicted. There is also a discussion about the somewhat complicated relationship during the last 150 years between the official Sweden and the different parties having an interest in the name-day calendar. The general public’s keen interest in name-days and their communication with the committee that manages and cares for the today most widely used name-day calendar (Namnlängdskommittén) is also described and analyzed, partly with the help of hitherto unused material.
