Most of us have a number that we have an affinity with but where did the concept of a lucky number come from?
In many cultures around the world, seven is considered a lucky number. Some believe it is because of our positive associations with the number and once you start looking you see them everywhere. There are seven days in a week, seven colours in a rainbow, seven continents across the globe and even seven wonders of the world. 
In Chinese culture eight is the luckiest of numbers, it is considered auspicious and represents prosperity and success whilst in Germany four is a lucky number, the same number of leaves as on a four leaf clover.
In Italy three is considered the perfect number, the triangle is an indestructible shape and it also holds connotations of the Holy Trinity. Italians also consider thirteen to be a lucky number, it is strongly associated with the 13th Saint, the saint of finding lost people and things.
We carry the same superstitions about ‘unlucky numbers’ and it’s not unusual for hotels to entirely skip a 13th floor or for airlines to omit the 13th row in their aircrafts. In China seven is unlucky, the seventh month of the Chinese calendar is considered ghost month.
For most of us our ‘lucky numbers’ stem from superstition, birth dates, maybe just the number we would feel most drawn to if asked to choose a number at random. Either way, if the law of attraction is to be believed, then having a lucky number can be seen to bring health, wealth and happiness.
