traditionally in western cultures,birthdays are celebrated within the family.a highly decorated cake with a certain number of candles to indicate the age of the person is the main thing in such celebrations,along with singing and a wish at the end of the singing,blowing out all the candles as a gesture of good luck.birthdays of significant digit change such as 1,10,40,50,100 are usually the ones which are more grandly celeberated,along with 18th (legal age) and 21st (legal drinking age in USA).for the most part,celebrations are quite similar in both eastern and western cultures,with the numbers celebrated in china being slightly different as in chinese culture the significance of 60,73,84 and such are much greater than the others.
