The Old Farmer's Almanac daily calendar gives you quick reference for the significant events on any day throughout the year.
Lovely, summerlike days that occur around October 18 are called Saint Luke's Little Summer in honor of the saint's feast day. Around this time, Saint Luke's feast day, there is a period brief period of calm, dry weather. Of course, it's difficult to generalize today across the vast continent of North America, but the temperature is usually mild and the leaf colors are turning a gorgeous color. It's a good time for a brief vacation or visit to a park. In Venice, Italy, they say: "San Luca, El ton va te la zuca" (Pumpkins go stale on St Luke's Day), but here in North America, pumpkins are enjoying their finest hour. Saint Luke is the patron saint of physicians and surgeons so it seems only fitting that the good doctor give us these calm days. In olden days, St. Luke's Day did not receive as much attention in the secular world as St. John's Day (June 24) and Michaelmas (September 29), so it was to keep from being forgotten that St. Luke presented us with some golden days to cherish before the coming of winter, or so the story goes. Some folks call this Indian Summer, but that officially occurs between November 11 and November 20.
