Be Late for Something Day is observed on September 05, 2018 and gives you the opportunity to dial your fast paced living down a notch and to take your time. Especially people who are never able to be on time are going to love this day.
The best way to celebrate this special occasion is: make an appointment for this day and be late for it on purpose. That's it, easy but it works guaranteed. But watch out: Don't make it a Be Late for Something Week. At least your boss won't be very amused by your new attitude.
