Answer: As soon as you can. Dates usually fill up fast (especially as we head into the Christmas season when a lot of engagements occur), and a lot of professional wedding DJ’s fill their calenders early on.  A lot of times brides will book their caterer, cake, venue, and other vendors before they book the one vendor their guests will remember the most, their DJ. You will find the planning process for your reception will be so much easier if you book early, so make your DJ a priority vendor when it comes to booking!
