Every day, PiDay opens to today and shows you exactly where that date appears in the first five billion decimal digits of pi. Search for your birthday, an anniversary, or any date you care about, then see where it lives in infinity.
PiDay searches multiple date formats and highlights the best match, so you can explore your date from different calendar conventions and compare where each one appears.

PiDay keeps things simple:

A decade worth of bundled dates, or search any string using a live lookup service for dates outside the bundled range.
If you’ve ever wondered whether your birthday is hiding in pi, this is the app for you.
