I like winter to start in early December. It sucks when the ski resorts have little to no snow during the Christmas break.
Before university, I wanted winter to end in late March, since my family would often go skiing during March break (which is a week off school in the middle of the month). Now that I'm in university, I would say early March, since universities don't have March break. Instead, we have Reading Week which is in February.
As much as I like skiing, it's also exciting to replace the winter jacket with a hoodie during the start of spring
