Hello VC
1. He hasn't been given chocolates on Valentine's Day to date.
2. He hasn't been given chocolates on Valentine's Day until now.
#1 implies that he's never been given chocolates on V's Day.
#2 implies that he's just received chocolates on V's Day for the first time.
If anyone out there is planning ahead, by the way, I prefer not to be given chocolates on Valentine's Day. Some Scotch would be most welcome, though.
(Just thought I'd make that clear.)
MrP
