March 14th, 2015 was 3/14/15 (in USA date format) which was the first five digits of the mathematical constant known as Pi or π.
This once-in-a-century opportunity needed to be celebrated!
To take it even further, you could have started your celebrations at 9:26 AM or PM which formed 3/14/15 9:26, or otherwise known as 3.1415926! If you really wanted to take it to the extreme, you could have tried to countdown to the 53rd second of 9:26!
π Countdown: π
