Hack days work best with a critical mass of people. A half-empty hack day loses the energy. Finding a date that most of the team can commit to is the essential first step.

You pick a date. Several engineers have sprint commitments. Others have been promised to other teams that week. You postpone and reschedule until momentum is lost.
