​Calendar: Week of April 27

Here's a look at the week ahead on our "Sunday Morning" Calendar:

On Monday, actor Robert Redford receives the Chaplin Award from the Film Society of Lincoln Center in New York.

On Tuesday, the Supreme Court hears oral arguments in cases brought by four states that are seeking to uphold their bans on same-sex marriage.

Wednesday is Duke Ellington Day, a celebration of the 116th anniversary of the bandleader and composer's birth.

Thursday is Day One for the 80th annual NFL draft, held in Chicago rather than New York this year for the first time since 1964.

Friday is the kick-off, as it were, for National Physical Fitness and Sports Month ... the annual call to Americans of all ages to make physical activity a part of their lives.

And Saturday sees the 141st running of the Kentucky Derby, the first leg of horseracing's Triple Crown. The last horse to win the Crown was Affirmed all the way back in 1978.
