Holi is celebrated in northern India in February or March (a date 2 weeks before the 2nd full moon in the lunar calendar). It's a
spring festival celebrating the vernal Equinox,
& promoting fertility in the half-grown harvest. The festival of Holi takes its name from the term for a half-ripened corn, holika, which is also the name of a legendary winter demon that consumed children; Holi commemorates both the
well being of the crops & the destruction of the demon.
