Join with people around the world as this day promotes jazz’s roots and intercultural influence every April 30. All. That. Jazz. Many consider it “America’s classical music.” After all, jazz began in New Orleans over 100 years ago. Legendary jazz pianist and composer Herbie Hancock (along with the UN) helped create International Jazz Day in 2011. Read on for a musical look at a distinctly American art form — and don’t miss our list of four cool jazz subgenres.
Orthodox Good Friday

Orthodox Good Friday is celebrated Friday before Easter according to the Julian calendar and falls on April 10 this year. While many Western churches follow the Gregorian calendar while celebrating events, Orthodox Churches retained the Julian calendar. Thus, they observe Good Friday and celebrate Easter at a much later date than the Western churches. This day is also known as Great Friday, Holy Friday, and Holy and Great Friday.
National Sarcoidosis Day

National Sarcoidosis Day is observed all over the world on April 30 and we celebrate by creating awareness among people, volunteering for events, and spreading the word about do’s and don’ts regarding this chronic disease. Did you know, 70% of people affected by sarcoidosis are aged between 20 and 40? Also, women are more likely to develop the disease.
