This outer space December 2017 calendar (there’s one for every other month of the year too, if I remember to add them) is perfect for anyone who loves space. Also ideal for science fans, astronomers, and people who just like to feel cool (because outer space imagery is trendy). The design is a bright, bold nebula with white text and numbers. The word “December” is written in bold writing above the dates. This monthly calendar is 8 x 11 inches, so will print on both A4 and US Letter papers â€“ just cut around the edges.
