I had planned to have my ceremony at 5:15 and have it last about 30 minutes so that my guests could arrive at cocktail hour right as it starts (6 pm in a different venue), but everything I'm reading about constructing invitation wording says that it's not "proper" according to etiquette to have a start time that's not on the hour or the half hour. Everyone is telling me to put 5:00 and just start at 5:15, but I'm not going to be so rude to my guests. What is the appropriate wording for a 5:15 ceremony, or should I just suck it up and move my ceremony time to 5 or 5:30? Also, would 5:15/5:30 be "in the evening" or "in the afternoon"? I thought everything after 4 was evening, but some sources say that I'm wrong. Thanks!
