Period of 366 days (4,4)

Ross

I believe the answer is:

leap year

(Other definitions for leap year that I've seen before include "It contains an extra day" , "366-day period" , "when summer Olympics are held?" , "The longest period of 12 months" , "When the lady may traditionally propose" .)

I've seen this clue in the Evening Standard, The Mirror and The Independent.
