Performed Sunday instead of Friday the 2nd: satisfied? (8)

I believe the answer is:

appeased

I'm a little stuck... Click here to teach me more about this clue!

'satisfied?' is the definition.
(appeasing is a kind of satisfying)

I don't understand how the rest of the clue works.

(Other definitions for appeased that I've seen before include "Conciliated" , "Changed a deep sap and mollified" , "Calmed" , "Placated, pacified" , "Assuaged, mollified" .)

I've seen this clue in The Guardian.
