Some will choose a date for its convenience - school holidays, or a public holiday which ensures that all their relatives and friends will share their wedding day with them.
Some want to associate their wedding day with something symbolic such as St. Valentine's Day, or a significant date in the life of their immediate family.
And then there are those who believe some days are luckier than others, and indeed, will go so far as to read their horoscope to ensure that the wedding date of their choice squares with their stars.
The most interesting one is that wedding date which is so memorable that you just can't forget it. Last year it was the 10 - 10 - 2010.
This year it will be the 11 - 11 - 2011.
