First day of winter

In Iceland, the first day of winter, or Vetrardagur fyrsti, was last Saturday, October 26.

This cherished cultural tradition marks the seasonal transition and typically falls on the last Saturday of October, signaling the beginning of Icelandic winter according to the old Norse calendar. This calendar divided the year into just two seasons—winter and summer—so the onset of winter is considered to arrive earlier than by the modern Gregorian calendar, which starts winter in late November or December.
