Cherry blossoms start

The ``Vernal Equinox\'\' of the 24 solar terms begins around March 20th. The first bird of the 72nd season (around March 20-24) is the first sparrow to nest, and the second (around March 25-29) is the first bloom of cherry blossoms. Cherry blossoms are said to be in full bloom when 5-6 flowers have bloomed, and around this time the cherry blossoms, which are a symbol of spring, begin to bloom.
