Open from Nov 15s or 20s to Dec 23th or 24th, most Viennese Christmas Markets ("Christkindlmarkt", "Adventmarkt" or simply "Weihnachtsmarkt") are not so much for shopping as for eating and drinking. From midday until the late hours of the night, people gather at Christmas markets to drink mulled wine, punch, and chat to one another and the occasional stranger.

Charity auctions are common in Vienna. Some stores give their proceeds to social programmes (often second-hand store back-to-work programs similar to Goodwill, or other charity shops).
