I got nothing for this coming week in the way of cool number dates.  I’m sure there will be some nice summer days and there will be fun number discoveries, but not related to the dates so much. One potential exploration was suggested by my friend Lee, who suggested the following site about Tau day: http://tauday.com/tau-manifesto

Some say that Pi Day (3/14) gets too much improper glory, that Tau day (6/28, equal to 2*PI) is the more worthy number and date.

Whatever the mathematical foundations, it seems clear that Tau day will not catch on until there is some delicious desert named after it.
