A day counts when the low is at or below 0°F - the same count the National Weather Service reports as "days min <= 0" in Fargo's monthly climate summary.[2] Winters run July 1 - June 30, so one that starts mild and turns cold in January is still one winter. Measured at Fargo Hector International Airport; winters with too many missing days are left out. This count is air temperature, not wind chill - for that, see the wind dashboard.
