Dates
Traditionally, Indian Summer or “Second Summer” happens in November when a period of warm weather follows a cold spell or hard frost. Although there are differing dates for its occurence, for more than 230 years, the Almanac has adhered to the old saying, “If All Saints’ (November 1) brings out winter, St. Martin’s (November 11) brings out winter.” So we use November 11 to 20.
