Freedom of choice. People need to be able to make a choice where there appears to be no logical reason why they cannot. The US see this type of rule “Quaint” and “typically British”. The law may be due the times the register office is open or a place of worship. It could be that there is some historical reasoning that we have to get married in daylight! With so many wedding taking place in hotels etc, it does seem to be a law that needs to be changed. Not suggesting we go for “24 hour” weddings.
In England there is a limited time period that you can get married. This means that people cannot get married in the evening. Why? There is some historical reasoning behind this, but its out of date. Why cannot people get married in the evening?
