Q. We are writing an invitation for a New Year’s Eve party which will take place on December 31, 2015. Would it be referred to as New Year’s Eve 2016 or New Year’s Eve 2015? I’ve seen it both ways but can’t seem to find an authoritative answer. Thanks!
A. Since New Year’s Eve is December 31, there should be no doubt which year it is in. However, your own confusion suggests that it is not a good idea to write “New Year’s Eve [year].” If you’re afraid your guests will show up a year late, clarify by adding month, day, and year to your invitation.
