St. Patrick's Day is celebrated on March 17. It is a holiday known for parades, shamrocks,  Leprechauns and all things Irish.

The shamrock was a sacred plant in ancient Ireland,  it symbolized the rebirth of spring. 

Leprechauns: the legend is that the fairies pay the leprechauns for their work with golden coins, which the "little people" collect in large pots--the famous "pots of gold" often associated with leprechauns.

                       Irish blessing

     May you alwayshave work for your hands to do.
May your pockets always hold a coin or two.

   May the sun shine bright on your windowpane.

   May the rainbow be certain to follow each rain.

May the hand of a friend always be near you,

                 And may God fill your heart with gladness to cheer you.

"May the road rise to meet you
              May the wind be always at your back,
                   May the sun shine warm upon your face,
                                                 The rains fall soft upon your fields, and,
                   Until we meet again,
                        May God hold you in the palm of His hand."
