People crack me up calling Jan 1 an arbitrary date. It’s not. It’s literally the first day of the year.
People also crack me up calling Sept 1 an arbitrary date. It’s not. It’s suggested by US lacrosse. It’s used by other sports. It coincides with most school years nationally. It coincides with the youth lacrosse season.
When a date doesn’t meet whiny parents crying train gets loaded to leave the station. |
