In a word, yes. As I’ve mentioned before, Florida Rule of Judicial Procedure 2.514 took the confusion out of legal holidays for the Florida court system. The Rule now defines Legal Holidays as:
(A) the day set aside by section 110.117, Florida Statutes, for observing New Yearâ€™s Day, Martin Luther King, Jr.â€™s Birthday, Memorial Day, Independence Day, Labor Day, Veteransâ€™ Day, Thanksgiving Day, the Friday after Thanksgiving Day, or Christmas Day, and
(B) any day observed as a holiday by the clerkâ€™s office or as designated by the chief judge.
So if you had a deadline that should have fallen today, enjoy your extra day!
