Summary

A calculator that takes three dates as inputs and finds the number of days between the middle date and both the earliest and latest date.

This calculator is currently broken in Safari iOS, but it does work in desktop Firefox on Windows and perhaps even other browsers too! I will troubleshoot it Eventually™.

Closer Date Calculator

Enter three dates below and click "calculate" to see which date the middle date is closest to. (You can type them in in any order; the calculator will automagically sort them.) Find out if your favorite movie was released closer to your birth or today or if a historical event was closer to the American Revolution or the moon landing.

Dates are input and output using the Gregorian calendar. You're on your own if you're inputting dates prior to October 1582 or at the end of February during leap years, and you're even more on your own if you have dates using a different calendar altogether. For dates B.C.E., input a negative number for the year.

Note: this was only tested in Firefox during development and appears to break in Safari on iOS, returning NaN results for any valid input. I'll fix it eventually but I'm not particularly satisfied with this version anyway and would like to add features later.
