Golfer's Day is celebrated on April 10, 2019. It's for golf lovers and is celebrated by playing golf. Golf is a precision club and ball sport in which competing players use many types of clubs to hit balls into a series of holes on a course using the fewest number of strokes. Golf is defined as "playing a ball with a club from the teeing ground into the hole by a stroke or successive strokes in accordance with the Rules."
It is one of the few ball games that does not require a standardized playing area. Instead, the game is played on a golf course, generally consisting of an arranged progression of either 9 or 18 "holes". Each hole on the course must contain a "tee box" to start from and a "putting green" with the actual hole, and there are various other standardized forms of terrain in between such as the fairway, rough, and hazards, but each hole on a course and indeed among virtually all courses is unique in its specific layout and arrangement.
