Number seven, a very cabalistic and used number thru history, is considered lucky among other reasons for being the number of perfection. God, the Bible says, created the Universe in 7 days. Thus 6 is the imperfect number, this is why 666 is the number of Satan or the Beast. On dices, where seven is a winning number, to get a 7 you need one dice on 6 and a 1 on the opposite side on the other dice. All opposite side numbers adds to 7. This is only an additional contribution to the answer by Flizzera, which nicely answered this question.

it includes the combination of three and four. We can go on and on about three. In all the manifestations of 3 we find the condition of dynamic balance. The configuration of three always suggests movement from one aspect to the other, while remaining fixed. This phenomena can be seen, and often is described as the essense of life itself or soul. The number four is linked in several cultures, in the maps we create and the way we parcel land in the western world, to the 4 directions, or 'Winds'. North, South, East, and West. The directions contain an elemental life beyond their identity on a compass. While the understanding or interpretation of the qualities associated with each direction change slightly from one culture or place to another fundemental pattern exists. The directions contain qualities of : >youth/spring/beginning/daylight/East >maiden/young man/summer/fertility/warmth/South >adult/mature/fall/setting sun/hibernation/introspection/West >elder/wisdom/winter/perseverence/strength/clarity/North animals, gods and godesses, stories, songs...all the things of culture travel on the wheel in which the four directions turn. The combination of 3 and 4 to make seven is so very lucky because it combines all that fills our soul with all we find in life. This is what I finally decided one day. For me, it works.

It's because there were seven days to create the world as according to the bible
