The Indian festival of Holi typically coincides with the vernal equinox.
Spring does not always signal sunny days and warm nights. On the first day of spring, the North Pole begins to experience 6 months of straight sunlight, while the South Pole will experience 6 months of darkness.
In Mexico, the Mayans enjoy the vernal equinox with "The Return of the Sun Serpent." As the sun is setting, the shadows run along the stairs of the temples and appear to form a diamond-backed snake.
In Greek mythology, spring signals the return of Persephone, the goddess of spring and queen of the underworld.
During spring, it seems as birds are more active than any other time in the year. In the spring, birds are trying to find a mate, so they chirp and call to one another.
