> To the unobservant eye it may appear to be just any other day, but the engineers notice the difference. There will be significantly less interruptions by someone walking over to your desk, you won’t be pulled into meetings that distract you from features, and you know it’s an opportunity to accomplish a bulk of work laid out from your weekly planning meeting.

For these reasons, we have our own "Maker's Day" too, except we have them every day instead of every seven days.
