Oh just found this too:
"There are no legal restrictions on when the Rite of Marriage may be celebrated, with the exception of the Triduum, as long as the various guidelines specific to the particular parish are respected. When the Rite of Marriage includes a Mass
there are limitations as to dates and readings. Few parishes celebrate weddings on Sundays, but a few policies encourage couples to consider integrating their wedding into the regularly scheduled Sunday Mass to more fully express the support of the
parish community (See, for example, Gary, Sioux City, Kansas City/St. Joseph, and Louisville). When a wedding coincides with a major feast the readings for that feast must be respected. Weddings during penitential seasons must respect the church tone
and décor appropriate for the season."
In other words ... take it easy on the flowers and decorations, and also keep in mind that your anniversary is likely to occur during Lent most years too.
