In tennis, Grand Slam and Calendar-Year Grand Slam are two different achievements.

Grand Slam is winning all four major tournaments, also known as majors or Grand Slam events, in a single year. These events are Australian Open, French Open, Wimbledon, and US Open. Winning all four majors at any point in a player's career is also considered a Grand Slam.

Calendar-Year Grand Slam is winning all four majors in the same calendar year, from January to December. This is a rare feat and has been achieved by only a few players in the history of tennis.

Winning a Grand Slam is a significant achievement in itself, but winning a Calendar-Year Grand Slam is considered the ultimate achievement in tennis.
