Not all heroes wear capes. This is excellent and can't wait to get aluminium mac next to try it – don't think Space Black is a good way to go.

Author's another post on "The Seasons are Wrong" [0] is excellent too and I fully support both approaches.

The seasons idea is interesting -- to me, both proposals feel wrong. I think it's because the weather changes that I perceive seem to lag behind the changes to daylight length by a few weeks.

I would propose boundaries that align partly with how I perceive the weather, and partly with how we plan our year (by months): Summer starts June 1st, Fall starts September 1st, Winter starts December 1st, and Spring starts March 1st.
