When choosing a wedding date, think about the time of year you want to get married. Have you always dreamed of a winter wedding? Do you want to get married outside? Have you always loved the fall? Or do you want to get married over the holiday season?
In addition to the season, you also want to consider the people who are most important to you. Talk to these guests -- parents, grandparents, siblings, and best friends -- to make sure they are free on the date before putting down a deposit. You don't want to book a hall and find out that dad has a convention out of town that he must attend.
And keep an open mind when meeting with venues and vendors. If you want to hire a specific vendor, check with him or her first to make sure he or she is available on your date, then book the ceremony and reception space.
