No source documents a founder, a proclamation, or a first-observance record for Chocolate Day. It is the third day of India's Valentine's Week, the run from February 7 to February 14, a sequence that spread among urban Indian youth after the country's 1991 economic liberalization opened it to global brands and consumer culture. On the day, people hand each other chocolates as a sweet gesture of affection.
A bitter drink with a reputation
Long before it was wrapped in foil, chocolate carried a reputation for romance. Among the Aztecs, cacao was a luxury drink that picked up an aphrodisiac name, and the emperor Moctezuma was said to drink cups of it before visiting his wives. Centuries later in Europe, Casanova called chocolate the elixir of love. The link between chocolate and desire is old, even if, as scientists now point out, the chemistry never quite backed up the legend.
