I commute all year round, even when the temperatures drop into the single digits. Simple low temperatures are, at worst, a mild nuisance requiring suitable clothes.
Commuting is a great motivator to ride on very cold, and/or wet days especially since I know I will be asked, "You didn't ride today, did you?" I have a reputation to maintain.

I have on several occasions in reply to similar threads asked that when one tells their war stories, please add the miles ridden besides the temperature. For my personal best on my 14 mile commute I left the house at 0 degrees F in downtown Boston and arrived at my suburban destination at minus 8.
The best definition I heard of a cold weather ride is one where your water bottle freezes solid--a good index of temperature
and time (distance). For my commute, that usually happens at below 20, and more likely 15 degrees.
