What notice does condo board have to give to change meeting date?

I'm in New Jersey. Our election is tomorrow night. The only owners that were notified of course were those eligible to vote, but they are holding the open session right after the election on the same night which was moved up a week due to the election. No one has been notified of the change of meeting date. Any input on that? I read that you must give 48 hours notice of a change of meeting where the annual budget will be discussed or announcement of election results.
