  1. Useful, with a few caveats:

    * Doesn’t work with 24-hour analog dials
    * Doesn’t work in the Southern Hemisphere
    * Doesn’t work at night
    * Works best around noon
    * Varies slightly depending on time of sunset/sunrise
    * Need to add an hour with daylight savings time

    On my last trip to Australia I observed that I would frequently go in the wrong direction due to my inner sense of “North” being 180 degrees out of phase.
