A 175-year celebration is commonly referred to as a "quasquicentennial" or a "septaquintaquinquecentennial." The term "quasquicentennial" is derived from the Latin words "quasqui" meaning "one and a half" and "centennial" meaning "a hundred years." Alternatively, "septaquintaquinquecentennial" combines the Latin words "sept" for "seven," "quinta" for "five," and "quinquecentennial" for "500 years," emphasizing the milestone of 175 years.
The numeral is "one thousand, one hundred" and the year is "eleven hundred."
