Hello!

I have a question; why do we count at tennis like it is: 15, 30, 40 etc...?

Why is it like this, why not 1,2,3...?

Thank you very much for your answers!

The earliest "scoreboards" were clock faces. Yeah, it should be 15, 30, 45 (instead of 40), but that's the story.

The following web site contains this explanation:
http://www.historyoftennis.net/history_of_tennis.html
"Tennis scoring history

There are two theories which revolve around the Tennis scoring history. The first one states that the scoring has its origins in ancient numerology*. In medieval times, the number 60 was considered auspicious or “complete” in a similar manner to which the number 100 is considered to be a “complete” figure now. The medieval adaptation of tennis thus considered 60 to be the “game” with steps of four points like 15, 30, 45 (or 40 as it is today) and finally 60.

The second theory is attributed to the presence of a clock at the end of the tennis court. A quarter move of the clock hand was made after each break with the score being referred to as 15, 30, 45 and finally 60."

*actually the use of 60 dates back 4000 years to the Babylonians who extensively used 12, 60 and 360 because these numbers are all easily divisible by 2,3,4, and thus fractions did not have to be used in their systems of weights and measures. Hence, 60 seconds in a minute, 60 minutes in an hour, 12 months in a year and 360 days in a year, and a circle has 360 degrees.

no reason to be concerned, the world will not end with the galactic alignment, that calander is only one of 5 maintained by the mayans. it may be NIRIBU and the ANUNAKI you have to worry about though.

The reason it became 40 not 45 is because it became easier to say. It is easier to say 40-15 than 45- 15. A whole extra syllable!
