Is There a Difference between Eucharist & Holy Communion?

I always thought they were 'the same thing,' but--looking the schedule for an Episcopal Church's services--I see "Family Eucharist" on Christmas Eve and "Holy Communion" on Christmas Day.

Thinking about it, I guess 'Eucharist' is the "the preparation (breaking, blessing, transubstantiation-ing)" and 'Holy Communion' is "the distribution." But TWO SEPARATE SERVICES? Isn't the 'communion'-host only 'holy' if the ones who take it witnessed the 'Eucharist'?

Or is this some part of the Episcopal 'Apostasy' (maybe not 'apostasy,' but just 'breaking away from the Roman Catholic Church' ... same-difference) I don't know about?
