When should you send invitations to a graduation party?

If you’re planning to throw a party, let your guests know at least three to four weeks ahead of time; out-of-town guests should get a heads-up six weeks out. If yours will be a large affair, consider calling a local hotel to reserve a block of rooms at a discount, which will help ease the financial burden on your guests. Be sure your invitation spells out what the celebration will entail so that Grandma doesn’t travel 300 miles for a slice of pizza.
