because the most primitive of tennis originated in the palace, and would therefore scoring local materials. You can toggle the clock to get the points, each will get a sub-clock rotation quarter, which is 15 minutes (a quarter, a moment), Similarly, the clock will have two points to 30 points, of course, All are based on the basis of their convenience. This is 15 points, 30 points in the origin.

For 40 minutes, it is more strange, it is not a multiple of 15. This is because in English, 15 min pronounced "fifteen", as the pairs of syllables, while the 30 points pronounced "thirty", is also a two-syllable;, but 45 minutes, English pronounced "forty-five", into three syllables, when the British people feel a little awkward-sounding, does not meet the "convenience" principle, then put it into a double-syllable with 40 points (forty). This is what seems illogical for the origin of 40 points.
