"By the way, we can probably take it that the three year gap between Seasons 4 and 5 was closer to a three and a half year gap. Morgana would have been defeated around mid-May but Arthur celebrates his birthday three episodes into Season 5, and we know from Season 4 that his birthday took place after Samhain, most likely late November/early December."

If Arthur's birthday is in November or December, I think that the seasons cover even more than just one year, given that only a few epsiodes after Arthurs' birthday the trees are green and flowers are blooming. But, if I'm not mistaken, weren't the trees green in "Excalibur" in season one and also in "The Wicked Day?"
