Just received an invitation to a family wedding taking place at the end of April next year. I was surprised to get it so early and can't help wondering how many people can actually know for sure so far in advance.............circumstances can change a lot in that time, new job, pregnancy, etc
I sent out my wedding invitations about 10 weeks before and I seem to remember that we had to give final numbers to the venue about a week before.
YABU..............totally normal
YANBU...........too soon
