Father's Day is observed in Poland and Nicaragua every June 23, honoring fathers and celebrating fatherhood. The holiday was established in the early 1910s in the United States by Sonora Smart Dodd, who sought to create a day to recognize fathers, paralleling Mother's Day. Although many countries celebrate Father's Day on the third Sunday in June, Poland and Nicaragua have chosen June 23 as their date, though the reason for this specific choice remains unclear. Father's Day is not a public holiday in either country, and the celebrations typically involve families honoring their fathers, though specific customs may vary. The holiday has gained recognition in various nations over the years, but its observance and significance can differ widely.
