We're having the typical problem with the number 4, in this case putting "4:30" ("half after four o'clock in the afternoon") on our invitations as the start of the banquet. How would you word it so that guests arrive on time but we avoid a 4?
The ceremony is at 2:00 (2:30, really), and will only take about 30 mins before we head over to the reception, so it's tough to avoid running into 4 o'clock somewhere.
