Many golf tournaments are held in April, but the most famous tournament is the Masters, held in Augusta, Georgia. The four "major" golf tournaments are the Open, the US Open, the Masters, and the PGA Championship.
The reason why golf tournaments last 4 days and not just 1 day is because of the number of holes played. It would be too much to expect the golfer to play that much in only one day.

There are usually 18 holes in a golf course; some have 9 holes or some multiplier of 9 holes. I have played at golf clubs with 9, 18, 27 and 36 holes. However, a standard "round of golf" at most golf clubs / courses involves 18 holes.

A round of Golf is usually 18 holes. But if there is a match which is still a tie after the stipulated round, playoff holes can be played until the match is settled, there is no limit to how many holes are played, unless settled by the competition committee.
One round is 18 .. so 18 + 18= 36. ; 36 holes
