Here's a posting to help you in scheduling your officiant:

In general, the MOST popular time for wedding ceremonies is Saturday between 5-7pm (just before sunset) in June and September.  The NEXT most popular times are on Saturdays just before sunset in May, April, July, August, and October.  If you want to have photos of a beautiful sunset in your wedding album, book the officiant as soon as you book your venue.

Many couples get engaged during the Holiday Season.  This means MANY couples are scheduling officiants for their summer and fall weddings in the month of January.  In fact, my June schedule for early evenings is routinely filled by the end of January.

If your wedding ceremony is on a Saturday BETWEEN 5-7PM in June or September (the most popular months for New Mexico weddings):  SCHEDULE at least 6-9 MONTHS AHEAD.

Wedding Ceremonies on a Saturday in the warm months at sunset:  SCHEDULE 4-6 MONTHS AHEAD.

Weddings held on Sundays or Fridays are becoming more and more popular as venues are often LESS expensive on those days.  SCHEDULE 4-6 MONTHS AHEAD.

Scheduling an officiant, especially an experienced, popular one, is something you should consider early in your planning process! 

Scheduling a year ahead is not always necessary...however, it doesn't hurt!  A smooth and beautiful ceremony is the best way to start your wedding day celebration. 

Hope this helps!
