It depends on the holiday and the family. My BIL's birthday is December 19th. His family was never allowed to give him combined presents. We did one year and it was begrudgingly okay'd by his parents because the sibling Christmas gift budget for my family was $5 and his gift was way more than that and we technically got him more than one thing anyway (we were justifying the more expensive Christmas gift, not trying to short him).
If it's a holiday like Easter (which moves) or Thanksgiving (which moves) or St. Patrick's Day (which isn't always a big production), then it's not a problem. However, I prefer to keep big ticket holidays to themselves, and that includes anniversaries. (DD2 was due on my anniversary. She politely came 8 days early.)
