It’s March 14th (3/14) and its 1:59 AM. So that makes it 3.1415926 right now. At 26 seconds and some change it will equal PI exactly…
3.141592653987 is all that I know in my head. It’s not accurate enough for space missions or time travel but it’s more than enough for every day use. I think I used to know it for a few more digits but that’s faded away with lots of more important stuff I’m sure.
I like this animated image since it illustrates P relatively well as being 3.14(etc) rolls of the wheel.

I had noticed the “Happy pi Day” on one or two blogs but hadn’t stopped to look at the details… NOW I see… of course, this is the US-version of Pi Day then, because for most of the rest of the world “3/14” would mean the 3rd day of the 14th month :p
Wanted to point to what the rest of the world could use as Pi Day, and hit a brick wall!
– 3/14 wouldn’t exist, as I said above, and
– 31/4 wouldn’t exist either, since April only has 30 days.
Bummer.
