Not listed: Hintertux Glacier , Zermatt - open year-round on the glacier, so it never has an opening date.
We don't guess. We check every season since 2011: did the resort have a 30 cm+ base at mid-mountain by 15 December?
15 of the last 15 seasons hit a 30 cm+ base by 15 December; the median base on that date is 417 cm. The same record, month by month, lives on every resort page.

The Alpine season starts in October on the glaciers and ramps through November as the first high resorts open.
