Happy Pi day to all non-American applied mathematicians and scientists (like me) who make approximations!
This is in fact TeX related as I have a question, or perhaps a puzzle. How would I make the equation
$\pi \approx \today$
give the output that makes sense, given the appropriate formatting of today's date. Furthermore, suppose the equation were typeset tomorrow, one might like it to output `\pi \neq \today', if you see what I mean. And if it were typeset on March 14, it might give yet a different answer. I'm afraid I don't have any MWEs for these.
