History lessons never have to be boring again with the 'On This Day' Calendar. The wall calendar comes covered in 365 colored squares that are each heat-sensitive, so when they are touched, the cover disappears and a fun fact about something in history that happened on that day is revealed. When you remove your finger and the square cools down, the fact is covered up once again.
For example, if you were to touch the 'On This Day' Calendar on the January 27th square, you would find out that on that day in 1880, Thomas Edison patented the light bulb.
What's even better about the calendar is that there is plenty of room underneath the facts to still write down appointments and birthdays as you would on any calendar.
Also, since the 'On This Day' Calendar is not formatted like a regular calendar and goes by day of the month rather than the week, you can use it for years to come.
