No, the date is not a mistake! I got married in February 2010 and when we left the hall, we were given some items left there that were assumed to belong to the family. They didn't, and we've been trying (rather ineffectively) to find their actual owners since.
If your husband attended a chasunah (could be his own!) in Torah v'Yirah in early February 2010 and may have left a shirt or a sefer, could you let me know?
