World No Tobacco Day has been observed on May 31 since 1987, when the WHO Member States created it to draw attention to the tobacco epidemic — a habit that kills more than 8 million people annually, with 1.2 million of those deaths from secondhand smoke. National Macaroon Day celebrates the coconut-shredded-and-baked cookie that shares a name but not a recipe with the French macaron — the macaroon arrived in the U.S. through Jewish bakeries as a Passover treat because it contains no leavening. Trinity Sunday is the Christian feast honoring the doctrine of the Holy Trinity — Father, Son, and Holy Spirit as one God — observed on the Sunday after Pentecost and a public holiday in several countries. World Parrot Day was established to raise awareness for parrots in the wild, many of whom are threatened by the illegal pet trade and habitat loss. Eight million deaths, a coconut cookie, a doctrine, and a very long-lived bird.
