When did the invasion of Omaha Beach occur?

'Bloody Omaha' was one of two US invasion beaches in the D Day invasion of Normandy: June 6th 1944. (The other was Utah on the Cotentin peninsula) There were significant casualties because of the defenders enfilading the beach as the forces landed. Nonetheless it was a success, but the costs on Omaha were higher than the other beaches. (Gold, Juno & SWord)
