Eiffel Tower Day is a holiday that is all about celebrating the wonderful monument that stands proudly in the city of lights. The day marks the completion of the Eiffel Tower in 1889, taking 2 years, 2 months and 5 days in total to build. It was constructed for the International Exhibition of Paris, during the 100th anniversary of the French Revolution, and was named after the principal engineer, Gustave Eiffel.

World Backup Day is set aside as a reminder to back up your files, even if its once a year! A backup is a reserve copy of all the files youd be loathe to use. Theres nothing more traumatizing than having losing your phone, or having your hard drive crash, and having hundreds of valuable and irreplaceable documents or photos suddenly gone beyond retrieval.

Crayola Crayon Day Crayola began its life as a company when cousins Edwin Binney and C. Harold Smith took over a pigment business in 1885 that Edwins father owned. Since then, they have produced a core set of 120 crayon colours; but they have also come out with many unique sets; including metallic coloured crayons, gem tones colours, and even scented ones.
