Generally speaking Weddings tend to book between 12 – 18 months in advance. However this is not always the case! Given that the Notice of Intended Marriage must be executed and received by me at least one calendar month prior to your ceremony, my minimum time in advance is one calendar month and 1 day before your proposed wedding date.
My best advice is to get in touch sooner rather than later. However always ask the question, there may be availability!
