"Months of no sun" in Utah is a completely silly thing to say. Doesn't happen in Utah. Not literally, and given Utah's comparatively mild winters for "snow" states, it's a tough figurative argument to make as well. There are lots and lots of beautiful, blue-skied winter days in Utah.
I just googled this so I'm not accused of just making stuff up. Average days with sun in Utah (either sunny or partly sunny) are as follows during the winter months:
November: 19
December: 18
January: 17
February: 16
March: 17
That's not "months of no sun".
