Wednesday (i /ˈwɛnzdeɪ/, /ˈwɛnzdi/, or UK /ˈwɛdənzdeɪ/) is a day of the week in the Gregorian calendar. According to international standard ISO 8601, it is the third day of the week. This day is between Tuesday and Thursday. The name is derived from Old English Wōdnesdæg and Middle English Wednesdei, "day of Wodanaz", ultimately a calque of dies Mercurii "day of Mercury"
