Here is a Valentine's day card which is best for giving chocolate with E-card. Valentine's Day, also known as St. Valentine's Day, is a holiday celebrated on February 14th in which couples express their love for one another through greetings and presents. Given their similarities, it's been speculated that the celebration is derived from the Roman Lupercalia festival, which takes place in mid-February. The event, which marked the arrival of spring, comprised fertility rites and the random coupling of women and men. Pope Gelasius I forbade the observance of Lupercalia around the end of the fifth century, and is frequently credited for replacing it with St. Valentine's Day, but the holiday's exact origins are hazy at best.
