Hide and Seek: A Perpetual Calendar Julie Morstad

One side of this beautiful desktop calendar ("today") functions as a daily agenda, while on the other side ("some day") a clever mechanism allows you to predict which day of the week every date is until 2068.

Seek out your next birthday or summer vacation – the fun is never-ending! For day dreamers of all ages. Это и многое другое вы найдете в книге Hide and Seek: A Perpetual Calendar (Julie Morstad)
