I imagine that you’ve finally recovered from the hangover related to celebrating 1234567890 Day a few weeks ago. Today, the computer/math dorky holiday Square Root Day brings back all of the feelings of joy and wonder only a holiday such as this can.

The reason today is Square Root Day is because the day and the month are both the square root of the last two digits in the current year. So if we break it down:

This year’s two-digit representation = 09, or simply 9.
The square root of 9 is 3.
Both today’s month and day = 3.
Therefore it’s Square Root Day!

So party it up by eating root vegetables like sweet potatoes, radishes and turnips cut into squares. But don’t overdo it – give yourself time to recuperate for the next Square Root Day on April 4, 2016 (4.4.2016).
