LEGO has produced various seasonal and holiday-themed sets over the years. These sets often coincide with holidays like Christmas, Easter, Halloween, and Valentine's Day, among others. The LEGO Basic theme, which began in the 1970s, was designed to be a more general, non-thematic series of sets. Unlike the themed sets that revolve around concepts, the Basic theme provided a collection of standard LEGO bricks and pieces.
