A Christmas stamp is a postage stamp with a Christmas theme, intended for use on seasonal mail such as Christmas cards. Many countries of the world issue such stamps, which are regular postage stamps (in contrast to Christmas seals) and are usually valid for postage year-round (in some countries they have a discounted value and are for use exclusively on Christmas cards). They usually go on sale sometime between early October and early December and are printed in considerable quantities.
