The official countdown can be a little confusing.  It also only counts whole days.

I made a more granular countdown which counts by the second.  I waffled a little on when the clock hit zero, and decided that noon on July 31st -- the time when Will Call badge pickup opens -- is a good time.

Countdown is here

Thank you.  This is really cool.

The countdown is not factoring for the daylight saving time switch in March.  So until then you get this quirky behavior where it would say exactly (some number) days, 0 hours, 0 minutes, and 0 seconds at 11 AM Eastern every day even though the countdown ends at noon on July 31st.  Just mentally add in one hour if you look at the clock before the time switch.
