Only the military measures temperature with a calendar!
We had an unseasonably cold September once at a certain station. The squadron boss went to OC Admin and threatened to burn all his files to keep warm until the heating was turned on; however, the situation was solved after the Stn Cdr returned from Bentley Priory a couple of days later - where they had been basking in the warmth of the heating being on. "If it's good enough for them, it's good enough for us - get the heating on immediately", he told OC Admin.
